This post has some good information on raw messages:
I took on a different tactic and looked for drivers that relate to Tuya specific drivers:
Specifically pilfering from:
This has lead to me using:
def setHeatingSetpoint(preciseDegrees, delay = 0) {
if (preciseDegrees != null) {
def degrees = new BigDecimal(preciseDegrees).setScale(1, BigDecimal.ROUND_HALF_UP)
log.debug "setHeatingSetpoint({$degrees} ${temperatureScale})"
sendEvent(name: "heatingSetpoint", value: degrees, unit: temperatureScale)
sendEvent(name: "thermostatSetpoint", value: degrees, unit: temperatureScale)
sendTuyaCommand("0202", "00", "00000000"+zigbee.convertToHexString(preciseDegrees.intValue() * 10, 2))
}
}
private rand(n) {
return (new Random().nextInt(n))
}
private getCLUSTER_TUYA() { 0xEF00 }
private getSETDATA() { 0x00 }
private sendTuyaCommand(dp, fn, data) {
log.info "${zigbee.convertToHexString(rand(256), 2)}=${dp},${fn},${data}"
zigbee.command(CLUSTER_TUYA, SETDATA, "00" + zigbee.convertToHexString(rand(256), 2) + dp + fn + data)
}
I can now set the setpoint of the TRV from Hubitat. Will play some more when I have time.
The python code you show generates a payload and issues a zigbee command using that data which I suspect can be translated across to hubitat to some extent:
