How to update thermostat setpoint using MQTT ?

[Westcott1]

Yes, I have RTFM, and know that you put a "/set" on the end of the topic, plus the new value as the message.
When I do this, MQTT Explorer shows the new "set" value correctly, but the current value which does not change.
Path to setpoint -
zwave/Study/Study_tx/thermostat_setpoint/endpoint_0/setpoint/1
New setpoint (also published from MQTTexplorer) -
mosquitto_pub -t "zwave/Study/Study_tx/thermostat_setpoint/endpoint_0/setpoint/1/set" -m '{"value":23}'

@Westcott1 Do you see the message is received in ZUI logs? Is there any error?

Hi Daniel,
Thanks for replying!
I can't see anything in the log that looks like a message was received.
Certainly no errors (nor warnings).
However, this works correctly -
zwave/Garage/Garage_socket/switch_binary/endpoint_0/targetValue/set

Based on the topics in the screenshot (status says "Asleep" and it supports Wake Up CC), this looks like a battery device that doesn't support FLIRS. You need to manually wake it up for the command to be sent and received. This is true for all commands to battery devices.

Yeah true, but he should still see at least the command is received in logs 🤔 @Westcott1 if you try to change the setpoint from UI does it works?

Hi all,

The thermostat is a Secure Meters HRT4-ZW / SRT321
When I send to it, nothing shows up in the log, and the Thermostat Setpoint in the UI is unchanged.
HOWEVER - Kpine is right!
Only when the thermostat wakes, or is woken, is the new setpoint sent and logged, and only then the UI value changes.
I've changed the wakeup interval from the default of 86400 seconds to 300.
Thanks all.
