About one month ago I got a new electrical meter in the house. The new meter is a "smart" meter equipped with a data port. It is more or less the same type of meter that is used in a number of European countries, e.g. The Netherlands, Belgium, Sweden etc.
Norway has selected a different version with a RJ45 port with another protocol.The dataport is a serial "P1" port in the form of a RJ12 contact that sends quite a lot of data every 10 seconds:
c716b64e-dcac-4ea4-9b1b-8ee29eb55edc-image.pngThe data will show both consumption and production if you e.g. have solar panels at home.
My initial though was to use the Tasmota P1 Smart Meter with Mqtt. I tried this and it works, but unfortunately I got some serial data errors every 5-10th message for some reason so I decided to try another solution.
I found a few other alternatives and tested one of them. The upside with this version is that it is adapted to the Swedish data fomat that differs from the Dutch a bit and that it delivers the data in Mqtt form:
2aab179b-a9ea-4041-8c38-f73570206e11-image.pngThe hardware is pretty simple. For the Tasmota variant and most of the other solutions you need a ESP8266, e.g. a Wemos mini and then a transistor and two resistors (image below). The version I use is even simpler since it does not need the transistor.
For a lot of the meters delivered (DSMR 5 versions if I am right) you can power the ESP from the 5V provided in the RJ12 port, very handy.42092756-f6b3-4375-9000-04bcd1e22240-image.png
It is also possible to buy a readymade P1 meter, this one looks quite nice, although I have not tested it.
In order to get a good overview of the data from the meter I have started creating a dashboard in Grafana that gets data from Historian in OpenLuup. It is quite useful to be able to see the load over time per phase etc.
a8276d7b-6b39-4f3a-a663-353173c1da5b-image.pngI also managed to grab the hourly prices in json format and display that in the dashboard via some lua code in a scene.
At the moment I have built no logic around this, but it opens up posibilities for sure. In Sweden the electrical tarrifs will change from daily rates to being higher when demand is higher, perhaps then this can be used.
All in all a fun DIY project that provides some useful data out of the electrical meter. 🙂

I want to replace my NEST Thermostat with something only z-wave!
Right now the NEST thermostat handle everything, even the humidifier that need the "central" fan to fonction!
Any idea on how to migrate...

Besides having integrated the xiaomi vacuum cleaner robot to my system, I have actually also integrated a large number of air filters to my automation system (homeassistant -> bridged into openLuup) for quite sometime. I have been using them mostly to monitor the air quality in different rooms. All of these devices are wifi but are communicating through a local API. I was looking today at replacing also my foobot which is my very last cloud dependent devices (and a non critical one) and found/ordered this:
60.99US $ 38% OFF|Xiaomi Mijia Air Quality Tester 3.97 60.99US $ 38% OFF|Xiaomi Mijia Air Quality Tester 3.97Smarter Shopping, Better Living! Aliexpress.com
It can very likely be integrated into home-assistant and then openLuup the same way I have with my filters but what I found particularly interesting is its low cost and the fact that it can also serve as a BT gateway! Why is this getting me excited? Because I have long regretted the loss of Plantlink which was a zigbee platform for soil/plant monitoring which unfortunately was cloud dependent and went belly up. I have since been automating my garden watering based on predictive algorithm only, without sensors. (yes still with openLuup). I am now looking forward to see how this will workout as my better half is very invested in gardening these days...

So my house only has 2 wire lighting and due to the way it's been installed, plus our flooring options, conversion to 3 wire is not practicable in any case that I want (hope I got those the right way around!)
So it's only dimmer units for me (boo hiss!) even though I'm only ever using them as on and off.So what's going to happen if I put a non-dimmable LED bulb on a dimmer? is the dimmer going to get upset or will the bulb just come on at 100%? I'm never going to ask the bulb to actually dim, I only want on or off.
Thoughts?
Cheers

Quite a number of years ago I set up a few Arduino sensors that reported temperature to my VeraLite running UI5. I did this with MySensors, a quite nice community based platform.
I discontinued this mostly because that the combination of a rather flaky Vera and that the Vera when rebooting lost the USB connected gateway.Some time ago I started to look at this again, but this time using ESP8266’s and Tasmota. I think the credit for this partially is the plugin for Shelly and Tasmota that @therealdb has written, even though I have still to use the plugin. The other reason for reentering into this area is that my electrical supplier is replacing the electrical meters for a new smart meter. Today I use a blink meter from Effergy, but the new meter will have a port for reading out data. This also led me to Tasmota, there seems to be a functioning solution for this.
I must say that Tasmota is brilliant! Support for all kind of devices and sensors and super easy to use, also for multi-sensors, OTA update, good documentation etc. You can get parts on ebay etc quite cheap. It has also so far been very stable. You can also very easily adjust the sensors readout, e.g. TempOffset -1.5 gives an offset of -1.5 degrees.
I have put together sensors for temperature and humidity for use in the garage, the outhouse, on the attic etc. I have tested DHT22, DS1820B, BME280 and BH1750 so far and they all work without issues. The latter two I installed in an outdoor enclosure to use as a simple weather station reporting temperature, humidity, air pressure and light level.
I also got a MH-Z19B CO2 meter for testing to monitor the indoor CO2 levels. The initial feeling is that it does what it should.
In general I have pretty good wifi coverage with a few Unifi access points. One of the sensors is in a building some 25 meters from the house where the wifi is not that strong, but the NodeMCU has no problem with this. Quite impressive and a good addition to Z-wave for that kind of location.
Not owning a 3D printer I have had to resort to purchased enclosures and the old Dremel. 😊
For the CO2 sensor I put it in an old smoke detector enclosure for now.
I am sure that there are a lot of talent here that can do much better with a 3D printer!
CO2meter1.jpgYou can get the data from the Tasmota devices into OpenLuup in a number of ways. The obvious way is via MQTT. I have still to set this up at some point in time. The second way is to use the excellent SiteSensor plugin. I tested this but had some problems with reporting stopping after a few days for some reason. I probably got something wrong in the setup. The third option, that I currently use is via adding rules to each sensor. You can quite easily add rules for reporting data to a virtual sensor in OpenLuup, e.g:
Rule1 ON tele-AM2301#Temperature DO Var1 %value% ENDON ON tele-AM2301#Temperature DO WebSend [IP_adress:3480]/data_request?id=lu_action&DeviceNum=65&id=variableset&serviceId=urn:upnp-org:serviceId:TemperatureSensor1&Variable=CurrentTemperature&Value=%Var1% ENDON
With TelePeriod you can change the polling interval as required.
This method I think could be super useful for reporting back e.g. switch status from a Tasmota node much like I understand Shelly can do.
Some resources and notes I made on the way:
Using Tazmotizer to flash the ESP’s is very easy
List of supported sensors including how to connect, commands etc
A good pinout reference for ESP8266 variants
Tasmota rules documentation
Most sensors are either “Generic (0)” or “Generic (18)”, check for each sensor type what to use
For I2C sensors e.g. BME280 one must use tasmota-sensors.bin
For the MH-Z19B I had to flash the ESP before attaching the sensor, this could be a good practice always
Use the following url for the query in SiteSensor:

So, I'm at the 4th Z-wave devices and I still have trouble in getting my Vera operate my door gate, and getting the input from the doorbell. It's already all 220v, because I have an external modulo meant for integration.
So, last night I had an idea: why not use a Shelly 1 as both sensor and opener?
If you need instructions on wiring, here's an image:
Shelly 1 can operate the output independently from the input. So, I prototyped this:
I attached to the doorbell sensor O attached to the gate openerIt seems to work on my bench, because I can call the endpoints when the button is pressed or the input is triggered, so I can update virtual devices and execute all the logic I want. I usually integrate these devices with MQTT, but it's not necessary in this case, since I can live with a doorbell buzz being missed.
Bonus point: you can run it at 12v if you want.83c3d861-0169-454d-bd2b-1105042bdfa8-image.png
Next in my TODO list, the Shelly Universal, a 9 EUR universal binary inputs, with separated inputs and outputs (so, you can get 2 inputs and operate 2 outputs independently), that I'll probably use in my weather sensors project, where I'm using two Shelly 1 at the moment, just the get the inputs.

Seems to be working fine except I get an error notification via email 'Error during perform command execution: Error: Invalid argument' every time setpoint is changed from controller. Also does anyone know if the 'Button' child is useful?

I didn't see an existing Topic for heating-ventilation-air conditioning, so here goes...
Is anyone successfully controlling a "mini split" (i.e. ductless) A/C or heat pump system at home? I will be adding such a system soon to new construction, and wondered if certain brands/models interface better via Z-Wave or WiFi than others in a HA setting.
I know a bunch of these "splits" come with handheld remotes, but having robust Home Automation control (preferably without a dedicated plug-in needed on the Vera side) would be idea.
Happy to hear suggestions. Thanks!

Hate it when I blow stuff up LOL.
TKB Home RGBW Z-Wave module. Was briefly using 2.5m of RGBW LED strip and I thought I'd chance using a spare 12v power supply I had. Not enough watts it seems.
Red channels has a fault now and when the device is powered off in Vera the red channel remains lit up.

The part that's blown is a A2sHB transistor.
The device still pairs to Vera and all the other colour channels work fine.
If my eye sight was good enough I'd have a go at soldering in a replacement A2sHB chip.
Not the best RGBW module anyway it had some issues with its functionality in Vera. So kind of glad it blew up 😁 I've got a new Fibaro RGBW V1 module to replace it.

Shelly i3 is an unbelievably cheap (9,99 EUR/USD) WiFi device that’s part of the fantastic Shelly family. It supports REST API, MQTT and much more.
mundzhos Shelly i3 | Shelly Cloud Shelly i3 | Shelly Cloud 10It’s just L,N and 3 inputs. No relays, so it’s a scene controller with bonus point to the fact that you can use your own buttons and keep the aesthetics of your house. Bonus points for WAF. It’s very small, so it will fit in your standard wall box easily.
While I built my own Scene Controller Virtual Device and I’m using MQTT for other devices of the family, Shelly can call your HTTP endpoints on button presses and in this case is more than enough.
The buttons support different actions (press, long press, double/triple press) and you can just call a service endpoint, or update a variable:
f3e509c0-f2a7-4f40-a099-af765e87c9fe-image.pngGo get it if you need a very cheap, very reliable scene controller for your home.

I've just completed my setup (after exactly 3 years from moving in, priorities!) and even if I wrote all the code in C#, I could port it easily to LUA (I guess 😄 )
I've used Fully Kiosk Browser + 3D Printed Mount (check https://makesbymike.com/) and a custom HTML dashboard, all running on an Amazon Fire Tablet:

WAF is very high 😉
Sorry for the Italian interface. First row is temperature/humidity sensors (esterno = outside, piscina = pool, salotto = open space, zona giorno = 1st floor, zona notte = 2nd floor, lavanderia = laundry room).
Then I have a bunch of commands/scenes sent to Vera to change blinds/roller shutters (they are automatically managed, but wife pretends to be smarter than code, from time to time 🙂 ). Last row has notifications for washer/dryer, with the cycle end date. When doing its cycle, the background becomes orange, then green when completed. It's probably the best feature, since the laundry room is in the basement. There's also a link to cams (videosorveglianza) and I automatically open TinyCamPro in case of movement outside/doors/gates are opened.Is there any interest in a generic wall mount tablet plug-in, offering simple dashboard (maybe json-driven) and integration with Fully Kiosk API?
I'm currently dimming screen on/off, get the battery status and schedule a 20-80 cycle for the battery, via a smart plug and a bunch of lua code. I planned for this when I did the electrical setup, so the tablet has a standard european 503 (recessed) box with ethernet, that I attached to the 5V into the network closet to feed the tablet. I'm updating the screen via AJAX every 30 secs.
Here's a behind the scenes photo as well 🙂

Last month I upgrade some doorlock with batteries with this...
f07daa0a-a8e0-4cf2-bf47-1970f151058c-image.png
It's very useful for a place like the shed that you don't go there often during winter 😉
So for a total of 6 doorlocks, 3 are now with that!
-
I'm still on a legacy door lock, mainly because we have a fenced house, and we're leaving the lock unlatched for the day, to close it at night. But I've got some spare time (lockdown coming on monday for two weeks in my region here in Italy) and I need to fill it with something to do. Plus, it'd be fun 🙂
I'm seeing there's a local API, so I'll probably go with the MQTT to luup route (https://developer.nuki.io/page/nuki-bridge-http-api-1-12/4), or write a native plug-in in LUA - I'm undecided.
I'm looking for feedback from people here in Europe, since it seems to be available only here.

Caveat: I'm still bored, so I'm building a lot of things lately (I used to travel a lot, so the last year has been really different - but I digress).
Last week I built two car sensors using a Shelly Button1 in each. It's a new device, with a battery and USB charging (see https://shelly.cloud/products/shelly-button-1-smart-home-automation-device/)
I've placed one in each car under the leg rest. I'm parking outside (my house is modern architecture, I have a covered terrace that's my open space, so cars are outside the garage, but covered), but WiFi is still reachable.
When plugged via USB, the device is sending a new MQTT message upon boot, and that's great for leaving home. It usually takes less than 10 seconds from when I open the car. This action will open my car gate unless party mode is on or the gate is already opened. It will automatically close it after 40 secs.
When coming back, it will reconnect in seconds (less than 10) and send a new online MQTT message. The trick here is to get the uptime via an HTTP call to /status (I've asked them to add to the MQTT message) and if more than 10 seconds are passed from the last boot, I'm assuming the car is coming back and the gate needs to be opened, and then closed automatically after 40 secs (again, if no party mode is enabled and if the gate is closed upon arrival).
It's a very simple thing to do, but I'm loving it. Obiously, my wife was like "you're really lazy", but I know she will love this eventually. Saving me from 10 clicks to a remote is what home automation really is 🙂

Hi folks
Hope you're all keeping well.
Working as we are in lockdown has shown some issues in the heating of our house. Basically we have a Horstmann SRT321 in the Hallway with its partner connected to the boiler. That bit all works wonderfully.
Problem is when I'm up in the office, it gets a bit chill unless I turn the the Secure in the hallway up. But then the rest of the house get OTT.
So I thought perhaps I could fit TRVs to all the rads (probably a good idea anyway) but unless I'm wrong, unless the SRT321 has a call for heat, there's going to be no hot water for the rads when the TRV opens.
So I'm still cold.
Can I associate each of the TRVs to the boiler control (in the same way the SRT321 is) and get a call for heat directly, or am I going to have to do this programatically.
Or am I completely wrong in how to approach this?TIA

I'm searching a second-hand Vera Edge/Plus in Europe because I want a fallback solution and a spare unit to better develop plug-ins, but I'm struggling to find it. Any suggestion?

I finally ordered 5 inovelli dimmers last week! Installed the first one already and it's not "easy" for the S2 authentication but after a couple of times it works!
I'm now trying to upgrade the firmware as Inovelli are providing .otz and .bin file

Hey guys...
Is it just me or the GE/Jasco switch or very sensible to power outage ?
Almost each time we have a power outage, I need to replace at least 1 switch to replace.
Each time, same behaviour, the blue led is flashing rapidely and nothing works.
Last power outage, I got 3 switches. 95% of our switch and dimmer are GE/Jasco.
-
So, I bought a new Christmas Tree led set from Twinkly (https://www.twinkly.com/).
The security of this thing is questionable, so first thing first I placed it in the blocked IoT Vlan.
The lights will just work (the 3d mapping of your tree is very cool, so effects are really mapped to the way you've set the lights), but, you know, I wanted to control them locally 😄 and I built a plug-in for it. Not sure I'll release it unless someone else is interested.
Twinkly pre lit Christmas Tree 600 count light purchased at Home DepotThey're not cheap and I know I could have accomplished the same with WS2812 leds, but it's worth mentioning if you want a quick and easy way to have effects on your Christmas tree.
Next year I'll definitely start my permanent led installation outside.

It's a bit of an issue. You can of course do this programatically if you have temperature sensors in all the rooms. But you'd have to drive the Horstmann relay programatically, which isn't ideal. The thermostat has some clever logic to drive your boiler in an optimal way (I think you can even set the boiler type in the Horstmann).
What I did: I put thermostats in the rooms that I want to have good temperature control in (3 rooms). The relay units near the boiler are simply wired in parallel: this defeats the cleverness of the boiler control... but only when more than one thermostat demands heat while being near its setpoint. The TRVs in those rooms are programmatically slaved to the thermostat: every so often the home controller reads the setpoint and updates the TRVs.
The TRVs in the other rooms are usually set to 14 degrees. At the moment I have them set so they go to 20 degrees when I turn the lights on in that room, and I close one of the boiler relays for 5 minutes to draw heat into the radiator. These are small rooms and this works well enough.
By the way, I'm getting some serious savings by not heating the rooms that are not in use during the day.
-
Thanks, interesting solution. I wonder if I could add another Horstman stat to the same association group....
On OpenLuup (so far) I've not been able to control the relay anyway. Sure I could do it on Vera, but I could be mistaken.
Cheers
C
-
I didn't actually wire 3 Horstmann relays in parallel, it's one relay, plus 2 Fibaro dry contact relays (can't use a double unit, you can't associate the Horstman thermostat with the 2nd relay in the double unit). You can buy Horstman thermostats separately and save some cash that way. They associate just fine with regular switches (I have one associated with an additional switch for a floor heating pump)
-
Hmm, thanks.
Which makes me wonder if I can control the underfloor directly.
No! Rabbit hole!
C
-
I have 3 thermostats attached to a relay, calling for heat. If at least one of the thermostat's relays ask for heating, the relay is opened. My setup is a little bit complex, since I went for all electric (not very common here in Italy), so I have a pellet stove as well. This is turned on by the same thermostat and I can choose to heat via electricity or pellet.
But the design is very similar to yours. I think it's pretty normal to have multiple thermostats and a common relay.
-
OK I shall look into that. Thanks, all!
