Z-Wave sent "Radiator 01 Thermostat" increase heat setpoint to 22.0°
Z-Wave sent "Radiator 01 Thermostat" mode status request
Z-Wave sent "Radiator 01 Thermostat" temperature status request
Z-Wave sent "Radiator 01 Thermostat" heat setpoint status request
Z-Wave received "Radiator 01 Thermostat" mode is heat
Z-Wave received "Radiator 01 Thermostat" temperature update to 18.5 °C
Z-Wave received "Radiator 01 Thermostat" heat setpoint is 22.0 °C

autolog wrote:Typically this situation can caused by clicking the up/down arrow (to alter the Heat Setpoint of the device) just after the commands have been sent to the Stella-Z. It seems to recover normal operation when the device's next wake-up happens.

Are you referring to the Indigo UI (up/down arrows) to change the setpoints or the physical buttons on the Stella-Z?
And can you turn on debug logging (via Interfaces->Z-Wave->Configure...) and get a log snippet showing the problem?

I am *VERY* interested. Can you keep us up to date with your project? My intention is to zone my own home in a similar manner but have been frustrated by the one hour delay and lack of reporting by the Danfoss. They dropped the ball with that design ... so close, yet so far.
But the Stella seems to address everything. They really got it right. The Stella reports temperature *and* reacts quickly to a new setpoint. To my delight, it is also quite good looking, not as pretty as the Danfoss but not bad at all.
It looks like the combination of Indigo and the Stella TRV provide way to control the heating system on a room by room basis. Since indigo can detect which people are in the house, rooms can be cool when they are absent. This alone will pay for indigo because heating oil is so expensive. Sweet.
My intention is to wire the boiler room switches in parallel with the existing three zone programmer so we have a plan-b in case the z-wave equipment lets us down. If I make the wife cold she will make me rip it all out

wysinawyg wrote:I can presumably get close to the same effect with just comparing set point to actual temperature, but it'd be cleaner and more elegant (and would used any TPI logic that the Stella-Z may have) if I could look at the actual call for heat.
