@AuthenticCamel I added support for IFTTT, so if the temperature goes low, recovers or goes high the IFTTT URL will be sent the following data, here is a test from temp recovering. I'm guessing from there you would have your app trigger your relays? Let me know how this works for you.

First setup the URL and connect to it in settings
IFTTT Settings

Then toggle on the IFTTT option on the kettle
IFTTT Kettle
