Tuya-Convert might not be possible for this device if the manufacturer started using newest Tuya firmware since this template was published. Instead you can likely serial flash Tasmota without soldering with a flashing jig, if the device is easily opened.

After configuring your WiFi details and configuring the template, use the console to issue the following commands:

‘Backlog TuyaMCU 12,9; TuyaMCU 11,1’

  • TuyaMCU 12,9 configures the light switch
  • TuyaMCU 11,1 configures the fan switch

As the fan switch takes enums, we need rules to handle the fan switch when it’s used from the switch (Rule 1), and a rule to set the fan speed and on/off when changed via MQTT (Rule 2)

Next add the following rules:

Rule: Publish speed to MQTT when using the physical switch.

	on TuyaReceived#Data=55AA03070005030400010016 DO Publish stat/%topic%/SPEED 3 endon 
	on TuyaReceived#Data=55AA03070005030400010117 DO Publish stat/%topic%/SPEED 2 endon 
	on TuyaReceived#Data=55AA03070005030400010218 DO Publish stat/%topic%/SPEED 1 endon

Rule1 ON

Set speed when commands arrive from OpenHAB via MQTT.

0 = Off, 1 = Slow, 2 = Medium, 3 = Fast, 4 = On (last speed)

	on Event#0 DO Power1 0 endon  
	on Event#1 DO Backlog Power1 1; TuyaSend4 3,2 endon 
	on Event#2 DO Backlog Power1 1; TuyaSend4 3,1 endon 
	on Event#3 DO Backlog Power1 1; TuyaSend4 3,0 endon
	on Event#4 DO Power1 1 endon

Rule2 ON
