Tado API change

Configuration

My Tado component stopped working one day ago.
I get this error:

I found this issue at github but no soulution.
Looks like tado changed their api…

It’s fixed, thanks to @syssi but home assistant showing now “null” if climate state is off.
Ha

It looks like an edge-case. If you start Home Assistant while the heater is off the target temperature of the past is unknown. If you turn on the heater on and off again it should show a target temperature. In my case it’s working fine:

Oh okay, I restarted my Home Assistant for some changes…
Thanks for your advice, again.

I am still getting the error HTTP 422 only when I try to change a TADO thermostat from Smart Schedule to OFF:

When I use other modes it is OK
