ELKO Wi-Fi Thermostat 16 A

Hi, I have just started playing with Home Assistant and I am trying to connect an ELKO Wi-Fi thermostat 16A (user guide here) to my HA.

The HA is running on an x64 bare metal NUC. I have a Sonoff Dogle Max and have been able to connect several Zigbee and Matter devices.

I have been able to connect the thermostat to the Elko Smart app. However, I have not found a way to connect it to HA. I found a post that indicated that this should work using the Matter integration, but as there is no qr code to scan (that I can see after the thermostat is installed) I do not understand how to do that.

Does anyone know how to connect this to HA?

Are you sure it supports Matter over wifi? There’s not a single word mentioning Matter in the user guide.

On a side-note I use different Namron thermostats in my house, they connect with Zigbee and are cheaper than the Elko ones.

No, I didn’t think the thermostat supported Matter, but as the post I linked said it did (assuming it is the same thermostat), I was wondering how I could connect it if it did support Matter.

I think you are out of luck I’m afraid, as far as I know there’s no way to connect this thermostat to HA. If you ordered it online you could use the “angrerett” to return it if you are inside the return window. Elektroimportøren sells thermostats that use Zigbee or Matter.

Thanks! No big deal, I just hoped that as it was “smart” I could connect it to HA.

Guess I’ll use the rainy weather to try to get my IKEA Trådfri lights to play nice…

Isn’t Elko ecosystem just white-labeled Tuya?
I personally don’t use any Tuya devices but that could be viable path to integrate the thermostat..

Thanks a lot for that tip! I got a bit further by installing LocalTuya. I used the client ID and Secret from here. When trying to add a device, it seems to detect the thermostat, shows its IP address and Device ID, but requests a “Local key”. The page I linked above also explains how to get the local key - but how would I run those python scripts from the Home Assistant server? I have installed the Pyscript Python scripting integration but don’t undertand how to create a script on the server. Apologies if this should be obvious…

I have successfully connected several elko smart wifi thermostats to HA now. I used the local tuya integration. It was some fiddling and adjustments needed with the help of AI. I have it showing the floor temp, this needed som experimentation to find out which inputs to choose in local tuya setup. I also set up a switch for the childlock feature. My thermostats now have full local control, instant 3-way response (elko app/HA/device)

Sounds good! How did you get the local key that seems to be required for connecting?
