My Secure SRT321 (main room thermostat) always took the setpoint sent from BLStat within a few minutes. Since a few days its not taking them any more. I have changed batteries. I have woken it up and rescanned it. Didnt help. It is still working, so when I manually change the setpoint on it, it still controls the boiler (I have an association which turns the boiler on when room temp is below the setpoint). So thats all working fine. It also stopped reporting the setpoint to HS3, so if I change it on the thermostat, its not reporting back to HS3, which it used to
