Enable rule with Rule1 1

Description: SetOption73 Decouples the buttons and relay The VAR1 can be thought of as “NextSpeed” and VAR2 as “Next Power”, if it makes it easier to read the code

Notes:

• Relay 1 is the main light relay controlled by button1 (the light button)
• Relay 2 is the main fan relay controlled by the button2 (the fan button)
• Relay 3 is the secondary fan relay controlled by the bottom3 (the array buttons)
• Relay 4 is the tertiary fan relay not physically connected to any buttons

Rule Logic

• Relay 3 and 4 will always turn on with Relay 2
• VAR1 is set to 3 at Initialisation and when the fan is powered off to ensure full power to fan to startup
• VAR2 is set to 1 at Initialisation to control the fan “next power state”
• Button 2 will always toggle the power to the fan (and reset state)
• Button 3 will always decrease speed one at a time 3 -> 2 -> 1 -> 3

*** HOME ASSISTANT - 2021.7 new fan layout needs different config. Old config has been deprecated and no longer works.

1. Do above steps (SetOption73, Rule1)
2. Add Rule: (edit the MQTT publish to suit your setup)

   Rule2 ON var1#State DO Publish stat/master-bedroom/%topic%/fanspeed %value% ENDON
   

3. Activate Rule

   Rule2 1
   

4. Home Assistant configuration.yaml Notes on fields to change:
   • name (change to your device name)
   • unique_id (anything unique)
   • mqtt topics: replace ‘master-bedroom/bedroomfanlightswitch’ with whatever your setup uses
