I am using Tado in combination with Google home and Smartthing / webcore
I prefer HomeKit which I have voted for but I am also planning to implement Athom Homey and probably also Home Assistant. It would be great to see more support for these by Tado as well.
I am actively using Home Assistant and Node-Red for controlling Tado. It works pretty well but I would appreciate official API to be finally published.
I have tried repeatedly to set up Homekit with Tado, but Homekit doesn't recognise the Tado bridge. It works well with Alexa, so I'll have to stick with that.
I have used Alexa and google, but I try and avoid using any manual controls. Better automation should mean I never need to manually control, via app or voice.
Ditto. Another Home Assistant fan here
Home Assistant would be my choice.
The only way to get good programmable control of smart homes is to use SmartThings/webCoRE.
Please, PLEASE integrate with SmartThings.
Also, I'm currently using Google Home for speech control, but could just as easily be Echo or HA.
I love my tado - the house is full of it! Integration of the best heating control system (tado, of course) with the best fully flexible smart home system (SmartThings/webCoRE) would really be a world beating system.
I use Alexa, it works pretty well, no complaints.
