    • ChatGPT - finally I can now retyre in piece and quite, knowing everting is in goof hands.

      A

      ChatGPT samples:

      Me:

      Tell me about an iot program called openLuup.

      It:

      OpenLuup is an open source home automation system that is built on the VeraLuup platform. It is designed to be easy to install and configure, and provides users with a powerful and versatile way to control their home automation devices. OpenLuup offers a wide range of features, including support for many popular home automation devices, scheduling, scripting, and integration with other services. OpenLuup is designed to be customizable, allowing users to create their own home automation systems. It is an excellent choice for those looking to create their own home automation system without spending a lot of money.

      Me:

      Write an iot program using openLuup.

      It:

      --openLuup IoT Program-- -- Initialize Variables -- local device_id = "MyHomeDevice" local temperature_sensor_id = "MyTemperatureSensor" local temperature_threshold = 75 -- Create Devices -- luup.create_device("OpenLuup Temperature Sensor", 0, device_id, "D_GenericSensor1.xml", "I_GenericSensor1.xml", "S_TemperatureSensor1.xml", "") luup.variable_set("urn:upnp-org:serviceId:TemperatureSensor1", "CurrentTemperature", 0, device_id) -- Start Timer -- luup.call_delay("check_temperature", 10, "", false) --Function to Check Temperature-- function check_temperature() local current_temperature = luup.variable_get(temperature_sensor_id, "CurrentTemperature", 0) --Check Temperature Threshold-- if current_temperature >= temperature_threshold then --Send Alert-- luup.call_action("urn:micasaverde-com:serviceId:HomeAutomationGateway1", "SendTextMessage", {PhoneNumber="1234567890", Message="ALERT! Temperature exceeded threshold!"}, 0) end --Reset Timer-- luup.call_delay("check_temperature", 10, "", false) end

      Me:

      Write an iot program using openLuup.

      It:

      Write an iot program using openLuup. -- openLuup IOT Program -- -- Variables local lampState = false local lampTime = 0 -- Functions function lampTimer() if lampTime > 0 then lampTime = lampTime - 1 if lampTime == 0 then luup.variable_set('urn:upnp-org:serviceId:SwitchPower1', 'Status', 0, lampDeviceID) lampState = false end end end -- Setup luup.call_delay('lampTimer', 60, 0) -- Main Loop while true do -- Check for motion if luup.variable_get('urn:micasaverde-com:serviceId:MotionSensor1', 'Tripped', motionSensorDeviceID) == '1' then if not lampState then luup.variable_set('urn:upnp-org:serviceId:SwitchPower1', 'Status', 1, lampDeviceID) lampState = true -- Set lamp timer to 5 minutes lampTime = 300 end end luup.sleep(1) end

      What??

      luup.sleep(1)

      Not good - looks like I still have some semblance of a job to fulfill.

      Me:

      An iot program called openLuup was written by akbooer. Who is akbooer?

      It: (note: answer redacted and as I understand it, also incorrect re: AltUI):

      akbooer is the pseudonym of the software developer and home automation enthusiast. He is the creator of the openLuup home automation software, which is an open-source version of the Vera home automation system. He is also the creator of the AltUI graphical user interface for openLuup.

      Me:

      Who created of the AltUI graphical user interface for openLuup.

      and

      Me:

      Who created of the AltUI graphical user interface for the home automation system Vera.

      Names two different people - mmmm.

      Regardless very impressive - give it a few more years.

    • Need help in finding the right smart switch for my kitchen lights

      M

      Hello,
      I have a kitchen light that can be controlled by two switches, using either to turn it off or on. I have been slowly changing things over to be a smart home but this is the first switch I am attempting to install.
      I am in a double wide modular home (mobile) that was built in 1994.
      At first I thought I would need a 3 way switch but when taking the normal switches apart I realized that was incorrect because the wiring on my switches are different than anything I could find online.
      For one a 3 way smart switch requires 5 wires and there are only 2 wires going into the primary switch with 3 wires going into the secondary switch from the primary switch (at least I think the 3 wires connect the two switches together). Images will be attached of the wiring.
      There are two wires (one black and one white) going into the first switch and 3 wires (black, white, and red) going out of that and into the second switch (I assume). The odd thing is the red wire going to the second switch is connected to the white wire going into the first switch and the white wire going into the second switch seems to be a bridge wire or a traveler wire. Not exactly sure. You will see what I mean in the images.
      I need to know what kind of smart switch I can use in this set up with one remaining a normal switch.
      Note that for some reason the images got switched around when uploading them. The image with 2 wires on one side and 3 on the other is what I think is the primary and the image with just 3 wires is the secondary.

    • OT: Universal Remote

      CatmanV2

      You lot are more likely to have a view than most I know. Our much used Logitech Harmony is (not so) slowly dying.

      And Logitech have discontinued the entire line.

      And no one else appears to be making something similar.

      Was going for a Sofabaton X1, but no numeric keypad. Sofabaton U1, but no favourites.

      Anyone got suggestions?
      Needs to have those features, oh and not be only a phone app.....

    • The Home Automation Controller Pyramid

      rafale77

      Since one member asked at one point about the "front end" and "back end", I drew this showing the controller from the base to the tip along with what I have found to be the best options from my testing. Almost every controller will try to integrate all elements, especially commercial ones but... they all have strengths and weaknesses so if one can have a medley of the best ones...

    • Thread removed - why?

      Black Cat

      I was just going to add my support for a Update Button for the bare bones version of MSR and find the thread has been removed.
      I'm wondering what was so provocative that required it's removal?
      Have we become as paranoid as an owner of another forum?

      Anyway +1 for an Update Button.

    • 3-way smart switches in separate buildings.

      D

      So, I think I'm in a bit of an unusual situation. I work at a camp & retreat center that has wifi throughout. I want to put a few switches in the office that can control outdoor lighting throughout the camp. We currently have switches in each of the buildings, but it is a particularly frustrating job to get all the lights on in the evening when it is brutally cold out or we are short staffed.

      Most of our staff is not very tech savvy (my boss literally has his wife print out his emails for him each day!!!) so, I'd love to avoid having to set up any sort of raspberry pi or new phone app.

      Is there type of 3-way switch that can connect to the wifi, turn on a light in another building AND turn on an indicator light in the office, without having any sort of wire running between the buildings? Hopefully looking for a simple solution without breaking the bank too.

      I greatly appreciate any input that you can give. Thank you!

    • X-10 replacement for a new wall switch (HomeKit)

      G

      I have a X10 wall switch system and I want to get rid of it. What would be the easiest transition to something more modern and easy to use with either wifi/homekit capabilities? My current X10 controls 3 zones in my bedroom. All zones are dimmable.
      Zone 1 is 4 canister ceiling lights. LED bulbs
      Zone 2 is 1 canister ceiling lights. Halogen Bulb
      Zone 3 is 1 canister ceiling lights. Halogen Bulb
      I have an old plug-in remote from Radio Shack and a wall switch with 3 buttons, each controlling one zone. (images attached)
      My wall switch has one two wires from the wall. One black, one white.

      Is there any solution easy to install without the need of an electrician? Thanks for any feedback.

      I just upgraded the firmware for the inverter for my solar panels and that made it possible to enable Modbus TCP.
      At a glance that would be perfect for live production data fed into my home automation environment but my lack of knowledge about the protocol and how to put the data where I want it failed me.

      What I have:

      MSR
      openLuup
      Vera Secure
      Ezlo Plus
      Mosquitto
      Homebridge
      Windows Server
      Ubuntu Server
      Quite decent PowerShell skills
      Enough Lua knowledge to write my own functions and handlers
      The inverters Modbus interface definitions

      What I want to achive:

      Something that can be run by systemd och anything else monitoring the status and keeping the Modbus connection alive.
      Publish readings over MQTT or whatever fits my setup, the goal is to feed the data into openLuup in someway so Historian can log the data for Grafana and display current production to HomeKit (as a mqttthing light sensor, since there is no other accessory suitable at the moment).

      Anyone implemented Modbus TCP in similar projects or have any guidance on how to reach my goal?

      Open for alternative solutions as well, all suggestions are appreciated!

        Hi,
        I was just browsing here and than saw your post. Just for the sake of answering I registered 😄

        At first we need some more infos about your inverter.
        You can ask the manufacturer about modbus details. (already done)

        Than this project might be exactly what you you are looking for:

          If you are looking for modbus integration then you might look at HomeSeer which has a Modbus plug in and supports MQTT
          There is an existing thread about Solar Edge which mentions that they (Solar Edge) do not expose panel information but you might want to follow this up.

              I have a Huawei inverter, so modbus support is hacky and I went the Shelly route. I have a Smelly EM feeding data in real time into MQTT - then to MSR and Home Assistant. I don't need fancy stats about my solar, just the production, in order to maximize self-consumption.

              26d8880e-1e2a-43ed-97c0-9c464d4ed3ca-image.png

              The graphs are a nice bonus that you'd create, using native HASS solar prediction as well.

              All that said, HASS has a native support for many solar inverters, take a look, since long term it's probably easy to use them than maintain your own integration.

                Thank you all for your ideas!

                @benni33 The inverter is a Huawei SUN2000-12KTL-M0 with a SDongleA-05 enabled for Modbus TCP. I'm guessing SunGather is for Sungrow inverters only but I gave it a shot in a docker with edited config.yaml but all I get is "Modbus connection failed".

                @Black-Cat I'm trying to avoid paid services but will investigate this further.

                @sender Modbus Controller looks like it needs physical RS 485 Modbus connection and not compatible with Modbus TCP?

                @therealdb That's an approach I could use as an alternative.
                I got this sort of working. It connects to the inverter and reads data but publishes only twice to the broker, then nothing. Going to fiddle with it more to see whats going on...
                HASS has been on my mind just doing my best to not involve even more systems than I already have.

                  I have the same inverter and it has been a pain. Recently, Huawei has stopped modbus TCP to be enabled by default and changed its port. It's not documented and the chances they'll do it again are high. Anyway, if you're OK with MSR, Shelly EM are easily supported. I don't have a battery, since I could sell my excess to the grid (but I've built a couple of automations to use it - we'll see this summer, where the excess will be way higher, since I have bifacial panels) and I don't have microinverters, since panels are facing south and in plain sight.

                  HASS has a nice UI for the energy part - and my wife loves it. I'm also storing the data into InfluxDB (via MSR) and I've built a couple of notifications aggregating data.

                      OK, after trying a few solutions a finally ended up with Home Assistant as a Hyper-V guest on my Windows server.
                      First I evaluated this by Emilv2 but it did not fit my needs and wasn't very stable.
                      The best option by far was this for Huawei inverters, I even tweaked the polling frequency down to 10s to have "realtime" data matching my ESP8266 hooked up to my electricity meter sending data every 10s.
                      Unfortunately HASS was not able to connect to openLuup broker so I enabled the HASS controller for MSR and echo the newly created sensors to openLuup.
                      I then wrote a MQTT handler for openLuup to set appropriate variables and do some math comparing electricity use and production and edited Historian to keep those for Grafana.

                      Been running it for almost 2 days now without any issues.

                      Some of the HASS sensors:
