Tried to control my Ngenic thermostat from Homey. I think this works:
-
Install https://homey.app/en-us/app/com.internet/HTTP-request-flow-cards/
-
Setup a flow with the PUT JSON (A40) card with the following parameters
Text 1 (url): { “method”: “put”, “protocol”: “https:”, “hostname”: “app.ngenic.se”, “port”: 443, “path”: “/api/v3/tunes/{tune-id}/rooms/{room-id}”, “headers”: {“authorization”: “Bearer your-id”, “content-type”: “application/json”}}
Text 2 (json data): {“targetTemperature”: 20.0}
Replace tune-id, room-id and your-id with the identification info relevant for your installation. A tutorial on how to access these can be found at https://developer.ngenic.se/

Hi Markus.
I have an Ngenic and would like to control it from Homey.
I could not find a tutorial to find the tune-id, room-id and your-id.
Or maybe the problem is that i am not a software developer 
Do you have time to explain how you found it?
Kind regards! / Mikael
Hi Mikael,
Look at https://developer.ngenic.se/ under “authentication” for your-id, it is referred to as “personal access token”
Then use the curl commands (available via a Linux/Mac terminal shell) under “a few usage examples” to retrieve the tune-id and room-id, referred to as tuneUuid and nodeUuid in the example.
Hope this will work out!
All the best,
Markus
Hi again
Thanks alot now i understand. I managed to get hold of my Uuids so i think i got it right now.
I had to reset my password for Ngenic since i couldnt log into the developer altough my password worked for normal Ngenic use.
But it didnt work i just get a error message…
Hi Great tip Markus
I have done the same and have the same error message as Mikael 
Note sure what the error can be. I remember having troubles setting this up. Perhaps there were multiple ways of doing a JSON PUT? Think it had to be an A40 request, see HTTP request flow cards App for Homey | Homey. You see the A40 info when editing the card on the phone but I cannot see this in the web interface.
I see that the title of your card is “PUT JSON (url)”, while my card just reads “PUT JSON” in the beginning. Perhaps that’s related?
Hi, old thread but:
just used the standard logic board for http request, HTTP PUT
URL:
https://app.ngenic.se/api/v3/tunes/TUNE_ID/rooms/ROOM_ID
HEADER:
Content-type: application/json
Authorization: Bearer YOUR _TOKEN
BODY:
{“targetTemperature”: 15}
Får inte rätt på detta lägger du in det precis som ovan?
Skärmdump från homey.app. Funkar det bättre så?
I get stuck trying to read the temperature sensors connected to ngenic.
I’ve found the token and room and sensor uuid and get a CURL GET to work on my MAC in terminal.
But I don’t get it how to translate that to a HTTP GET in Homey…
Any suggestions??
curl command
curl -X GET
-H “Authorization: Bearer abcd1234PRIVATETOKENabcd1234”
“https://app.ngenic.se/api/v3/tunes/{f3e2e629-8eb9-ec11-997e-e42aac6e0f30}/measurements/{0687242c-75cc-ec11-997e-e42aac6e0f30}/latest?type=temperature_C”
response:
{“hasValue”:true,“time”:“2022-09-20T16:25:28 Europe/Stockholm”,“value”:21.5625}%
were “value” is the current temperature
I work with this now, i cant really get it to work as you all write here. I get it to work in curl . How to translate from curl to work in homey pro flow? I try with card put http.But I cant change temp there. But in real curl it works.
has anyone got this working with homey pro 23?
@Markus_Nilsson - Kan du tänka dig att ta fram en uppdatering för Homey 2023?
