Secure Together SRT321/SSR303 or Horstmann ASR-ZW/HRT4-ZW (Updated DTH in post 61)

Anyone having issues with these?

They’ve been rock solid using @meavydev DTH but today I’ve had to setpoint changes not happen.

Symptoms as follows:

CoRE changes the setpoint to a pre-defined value at a specific time
The device acknowledges the setpoint change
The stat wakes up as expected

All appears fine, ST app thinks the stat is at the new set point but the stat does not. For example ST thinks the Stat is at 18 but it’s still at the previous setpoint of 16.

If I then moved the stat the ST app updates immediately.

Any ideas?
