The integration is working perfectly.
There are some steps someone that needs to follow, so maybe a clearer step by step instruction would be great since the most important step was at the bottom of the doc. (however maybe it was just me).
The integration has everything it should, at least for my Smarther 2. There are a few cards around with each one having pros/cons but i think we will see more more in the future.
One point though that needs improvement, is the speed of communication.
When you set temperature in HA, it is reflected instantly to the Smarther 2.
When you set temperature in Smarther 2, it is reflected after a long time, unless i refresh the web page myself.
Overall, you made my winter guys…!!!
