Hi
I’m looking to rework some code I found online so I can use it on Vera, and while I’ve managed to translate / convert a number of things, I’ve got stuck on a few things it does, around encryption/decryption etc.
All the original Lua code is here - > (https://forum.logicmachine.net/showthread.php?tid=232&pid=16580#pid16580 )
Plus there looks to be a python version too here - > (https://github.com/florianholzapfel/panasonic-viera/issues/9#issuecomment-476919658)
Here’s an extract of the code where AES 128 CBC is required?
function encrypt_soap_payload(data, key, hmac_key, iv) payload = '000000000000' n = #data payload = payload .. string.char(bit.band(bit.rshift(n, 24), 0xFF)) payload = payload .. string.char(bit.band(bit.rshift(n, 16), 0xFF)) payload = payload .. string.char(bit.band(bit.rshift(n, 8), 0xFF)) payload = payload .. string.char(bit.band(n, 0xFF)) payload = payload .. data aes_cbc, err = aes:new(key, nil, aes.cipher(128, 'cbc'), { iv = iv }, nil, 1) ciphertext = aes_cbc:encrypt(payload) sig = encdec.hmacsha256(ciphertext, hmac_key, true) encrypted_payload = encdec.base64enc(ciphertext .. sig) return encrypted_payload end function decrypt_soap_payload(data, key, hmac_key, iv) aes_cbc, err = aes:new(key, nil, aes.cipher(128, 'cbc'), { iv = iv }, nil, 0) decrypted = aes_cbc:decrypt(encdec.base64dec(data)) decrypted = string.gsub(string.sub(lmcore.strtohex(decrypted), 33), '%x%x', function(value) return string.char(tonumber(value, 16)) end) return decrypted endI can get to the point where I can create the parameters for the payload encrypt request (example below), it’s just the encryption/decryption I cant do..
data="1234" key="\\S„ßÍ}/Ìa5!" hmac_key="¹jz¹2¸F\r}òcžÎ„ 臧.ª˜¹=¤µæŸ" iv=" {¬£áæ‚2žâ3ÐÞË€ú "I’ve found this aes.lua (https://github.com/openresty/lua-resty-string/blob/master/lib/resty/aes.lua ) module online, but that requires loads of others modules too, most notably ffi.lua. Which I’d ideally like to avoid.
I also came across this aes128.lua (https://github.com/somesocks/lua-lockbox/blob/master/lockbox/cipher/aes128.lua ) but i’m not sure how that handles all the other parameters e.g specify the cbc aspect etc.
Finally there’s this aes256ecb.lua script (https://github.com/idiomic/Lua_AES/blob/master/AES.lua) , could that be converted to aes 128 cbc and then used in the above?
Any help/advice on this would be appreciated..

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 definitionsWhat 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 to all, I have a bricked vera secure that is replaced with new one. Old vera secure serial numbers are deleted from vera servers so I cannot use it. Vera secure's are orginally Sercomm's NA502 model devices. Recently I install openwrt to the old vera secure unit without problem. Is there any way to use it any automation system with internal z-wave. I install domoticz but I cannot setup internal z-wave unit, it only accept usb zwave radios. Is there any ideas?

Hello,
Looking to all the dev's and tinkerers on this community for ideas on how to implement a solution to my problem. Kind of a long intro, sorry.Problem statement:
I have a geothermal heat pump that has a loop that is slightly undersized. During the cold weather months in the Pacific Northwest (one or two months of the year), the loop can get below 32 degrees. If it goes on for a few days, it can generate significant frost heaving in my yard and under the flagstone deck, Actually fixing the issue is cost prohibitive.Current mitigation:
I have DS18B20 tied into Home Assistant and monitoring the temp of the fluid coming out of the loop and if it drops below 35 degrees, MSR triggers a Fibaro Implant to add a resister into the external temp circuit and fool the Venstar to think the outside temp is below 32 degrees and issue a Heat Pump lockout and switch to AUX heat. While this is working fine and the AUX heat is only coming on once or twice a day, I would like to simplify the setup so it runs on something other than HA and MSR. I think they are overkill for my issue. Also want this to be independent of anything else in the house so it can stay behind if I am not around to maintain.I only have two inputs and one output:
Inputs: Loop temp, Furnace running
Outputs: Switch relay to drop resistance to external thermostat connection on thermostat.
Logic is super simple:
If temp is below 36 degrees and furnace is running, turn on relay
If furnace stops, turn off relay.
I am sure even I can figure that out on Python.Trying to determine the best platform for a set it and forget it black box that works with as close to zero maintenance as possible.
Options I have thought of are:
Pi zero with a GPIO controlled relay ESPHome (Not very knowledgeable about that platform, but willing to explore) Arduino Anything anyone else suggestsAny ideas are appreciated.

Greetings,
I’m researching a migration from Vera+ to Hubitat C7 and want to know if anyone has successfully connected the Hubitat to the “HA Bridge” for local Alexia calls.
The HA Bridge does not callout Hubitat natively from what I see.Thanks for your assistance.

Hi all
Having some time off i’ve been able to invest a chunk in creating some plug-ins for Vera/OpenLuup, and will do what I can to post them in GitHub and add links on the Vera Community and here, for anyone who is interested.
But, being knew to any of this, I wanted to ask for any guidance on how and when I should share stuff ? How best do I share it ? Am I liable for anything I share? Is GitHub the best place ? What licenses should I associate with them ?
The latter is a strange one, as I don’t see how I can have any claim over the content/code itself, as I’ve learnt and leveraged so much from others..
To get the ball rolling I posted this on the ezlo/Vera site..

Hey guys,
I just registered here in the forum and honestly… I’m new to the whole topic. I‘m a web developer, so I‘ve quite a bit experience with java, js, sql and so on. But that may not help a lot in this new field.
I‘m looking forward to develop my own smart home device and I‘m looking for starting point. In General the specs are like:
The device should work with WiFi, I want to integrate it into my network I want to write an own app to control it, it may find the device in my network I want the device to be offline usable, if possible (without internet connection) I want the device to broadcast information in my network like „water is empty“, so I can use push messaging in the App it should be ready to as well work with Alexa or Apple Home Kit or Google Assistant as I Plan to develop a skill for them.Can someone provide me with some information I could start with? Like - are there microcontrollers I could go with or is it to complex and I need a raspy? Which frameworks / languages / libs could I use? I know how to do the things on the app side but not on the device side.

Vainly trying to get to the bottom of the 10 - 15 second delay for TTS with the Alexa plugin (still) anyone have a list of the possible Alexa hosts? Just wonder if the one I have (layla.amazon.co.uk) could just be slow.
Any thoughts?

Hello. First, excuse my english, please. I bought a Vera Edge looking for some way to make a digital ambient thermostat that I could manage remotely without a phone home from the device side. I am very disappointed with that device because all the "official" help of the brand goes in the way of to sign in an account and work with their cloud. I have some computer, network and linux knowledge but all my tests with the hub and a Qubino Flush 1D Relay has been unsuccessful. I connected both and I got to make some basic functions but I see myself very far to get my target. This is my last try to get something before I log in an account in getvera.com and look if I can make some progress in my project following that way.
Can somebody tell me some place where I can learn the basic concepts of this system? Guides, books, videos... Whatever it can help me in my project.
Thank you.

Node-Red on my Linux Debian box seems to be having issues now. It keeps saying repeatedly "Lost connection to server, reconnecting..." in the web browser.
I recently updated nodejs for MSR, I wonder if that might be related:
"Bump recommended nodejs version to 16.13.0; versions 14 and 15 will continue to be supported through March 31, 2022"
Nodejs version = v16.13.1
I have tried updating Node-Red that is now version v2.1.4
I also updated npm to version v8.2.0
I am not sure how or where to look at the log file for node red?
This is the contents of the nodered.service file in this directory:

Hi @ll, last days I migrated my last zwave device from Vera to zwave js in homeassistant. Out of 150 devices 1 did not go well initially but reinterviewing did it directly. Most work was to find the ex and inclusion procedure, 3 times, click, clack, whatever. I must admit that Vera is Lighting fast!!!!! With only 3 devices left, those were my under the floor switches I had to do last.
Now I am totally gone from Vera, altui, luup, etc. There's nothing more left for me on this forum. And since it was one of my "routine sites" reading I will save a few minutes a day skipping it.
I thank you all for all the kind help, warm words and laughter about the ezlo flop :-).
I hooe you all will be safe and healthy and whish you all the best!
I will stay on the homeassistant forum.
Goodbye!

Morning all. Hope all are well. Been a bit of a trying time here, but nothing we can't deal with....
.....apart from this!My coffee grinder went punk yesterday (wasn't even being used) and took out the main breakers. Once it was isolated I got everything back on line, except on TKB smart plug which was in the same double socket as the grinder.
OpenLuup claims it's failed. Z-wave server can't see it but it responds to the button pushes physically as I'd expect. (i.e. the socket turns on and off, and the LED flashes to indicate it's in inclusion / exclusion mode)
My plan is to see if I can exclude it then re-include it in z-wave server. If that doesn't work then I'll bin it, but if it does work can I then re-number it to match the original device ID and not have to trawl through my reactors? Any chance?

Some of you may know that I took at shot at building an alternate geofencing solution for Vera. The core of it was system agnostic, using the OwnTracks application and AWS lambdas to track devices and keep a central data, then disseminate that to the Vera via a websocket-based plugin. It worked with other apps as well, including Tasker and GPSLogger, but of the dozen people that were testing it, most used OwnTracks.
A lot was learned in the process, not the least of which is that the success of any such solution is highly dependent on the phone and its settings. Phone manufacturers love to set things up for the longest battery life, of course, but that's usually very anti-geofencing behavior. In the case of at least one brand, it was unusable and the settings could not be modified. It was also cost-prohibitive to maintain on Amazon, as AWS grabs a dime here and a dollar there and before you know it, it added $100/month to my AWS bill, which my wife deducted from my Scotch budget. Unacceptable.
But it's quite reasonable to use OwnTracks to a local endpoint, and I could pretty easily replicate the functionality as a local application, or maybe even as an additional endpoint built into MSR's API (still separate port and process, but in the package).
So the question really is... would you do it, or would you be too concerned about the security risks associated (e.g., dynamic DNS and NAT mapping in the firewall necessary for the phone to contact the service when not on LAN)?

Hello!
I want to trigger an event (like switching on a smart Zigbee power plug) when a regular light switch (that switches regular non-smart LED light bulbs) is flipped. Is there something I can put behind a light switch to achieve this? Or something to splice in between the switch and the light bulbs? A good option would also be Hue compatible.
Thank you!
Starting with smart home development
-
Hi,
I hope this is the correct place to ask. I wanted to start with developing smart home systems where I use a raspberry pie as a server and communicate through a phone or tablet.
But I do not know where to and how to start, I have knowledge in developing Web Application, Java and a bit react native.But which Development Language is good for smart home development? Would it be possible to achieve smart home projects with Webapplication and smarthphone app if they communicate with the same server?
Which additional knowledge do I need except development language? I looked on the internet a bit, but kinda got lost with all the information in it right now about smart home.
-
Are you looking to implement a smart home as a user, or learn about developing a smart from (either from scratch or as developer)?
Welcome BTW!
C
-
Hi what do you mean with "developing a smart"? I wanted to learn how to develop smart home systems but with my own application and not predefined ones.
For that I wanted to learn which language would be prefereable for smart home systems, and which additional skills do I need? For example is networking needed or anything else like that.
-
It's a big question you are asking here and you seem to want to start from scratch.
My question to you is why? Some of your ideas have been explored and executed for years and there are also already commercial offering in that direction with various levels of success.
I will give you just my opinion:
Development cycles for me go in this chronological order:- Make it work (design)
- Make it reliable (debug)
- Make it fast and efficient (optimize, often skept these days)
Now with more freed resource, you can have new ideas and repeat the cycle.
What language you want to use is up to you. There is no right or wrong answer. It ranges from Java/JS on NodeJS to Python to lua to C. There are examples of all of them and it is all a matter of taste and support.
JS example: iobroker
Python: Home Assistant
lua: openLuup
C/C++: many others mostly commercial solutions.The raspberry pi with a web server is one of the most common platforms and a good, but not great place to start: As you grow your system beyond the phase 1 of "Make it work", You may start finding limitations of capability, reliability and efficiency.
Also, the mobile app ideas are pretty common but... I am partial to eliminate them as much as possible because there are too many of them already and ideally, for the sake of efficiency, you would not need them if the home was ultimately "smart". Any configuration would have to be done on the server but mobile apps would be too limiting/small to handle the complexity. I see the mobile apps as a patch/addition maybe temporary convenience and not anything I would base/develop my system around. I am trying to eliminate the need for them and have been pretty succesful. If you need a dashboard, it can be done through a mobile page on the webserver.
-
@rafale77
I wanted to make this commercial so start doing business with it, thats why I wanted to implement my own systems. What would you recommend insteat of a raspberry pi? And what would I need alongside development? In order to achieve what I want ? How could I make my raspberry pi, smartphone app and for example a door lock communicate with each other? Would that be
Networking?What would be alternatives to control the smart home systems? if not by phone
-
-
So you mean like use a webapplication which communicates with the server and is just displayed on the phone/tablet right?
My biggest question is which skill I need to learn for comunication between the devices is it Networking or anything else?
-
My smarthome system has very little interaction with my phone/tablet except for the localization and voice control. I use no apps for these. In case of other failures only do I need a display but this can be done through a web browser on the mobile device though I use Homewave for convenience. Under normal conditions, I would not need any display on my phone or tablet.
For device, you can look at nVidia's Jetson or celeron based mini PCs. Skills you need are both around networking and also the various wireless stacks and APIs for smarthomes: Zigbee, Zwave, Thread. You could also just stick with wifi devices which seems to be the trend lately but I see this as less secure, more cloud prone, less efficient but more convenient.
-
@rafale77
Hey thanks you helped me a lot I at least am a bit smarter now
I have just a few more questions haha if I may.- What are wifi stacks?
- And do you know which skill is needed to assembly your own smart device? I would think a small pc like raspberry pi or an alternative with modules like wifi, bluetooth etc right?
-
wifi stack is a standard (802.11a/ac/ax) and you probably don't need to learn much about it. The wireless stacks I was speaking of were the others: zwave and zigbee in particular. For wifi, devices usually have a local API you can work with.
I don't know how to answer your second question... You can buy these all made and use USB modules for them.
-
Thanks for the answer you really helped me out
Is it ok to contact you if I have further questions? -
You are welcome. Not sure if I can answer all of your questions but it doesn't cost anything to ask. This forum has a lot of folks who started with a commercial solution which ended up being a dead end and decided to go off on mostly open source platforms, many developed, discussed and shared here.
-
@rafale77
Thanks I will keep that in mind Of course it is never guaranteed to succeed but trying is something important I think -
Do not underestimate the amount of effort and time this is likely to take... especially when you get a few users on board.
