{"NAME":"Tuya Shutter","GPIO":[157,0,54,10,22,19,0,0,17,21,53,23,52],"FLAG":0,"BASE":18}

Requires configuring shutter support.

Rule1 on Power1#State=1 do backlog Power3 0; Power2 0 endon
      on Power2#State=1 do backlog Power1 0; Power2 0; Power3 0 endon
      on Power3#State=1 do backlog Power1 0; Power2 0 endon
Rule1 1

This combines to:

Rule1 on Power1#State=1 do backlog Power3 0; Power2 0 endon on Power2#State=1 do backlog Power1 0; Power2 0; Power3 0 endon on Power3#State=1 do backlog Power1 0; Power2 0 endon

Or use the Interlock settings like below (or use both for safety).

Added some commands too:

InterLock 1,2,3  # lock the relays, only one relay can be on
InterLock    on  # switch interlocking on
PowerOnState  0  # keep relay(s) OFF after power up
PowerRetain   0  # don't retain states
PulseTime1  145  # set relay 1 activation to 45 seconds (+100 for 1sec interval)
PulseTime2    1  # deactivate button 2 immediately after activation (disables relays)
Pulsetime3  145  # set relay 3 activation 45 seconds (+100 for 1sec interval)
SetOption1    1  # restrict button-multipress to single, double and hold actions
SetOption26   1  # use indexes (Power1 iso Power)
SetOption56   1  # Wi-Fi network scan to select strongest signal on restart
SetOption57   1  # Wi-Fi network re-scan, alternate AP

This combines to:

Backlog Delay 50; InterLock 1,2,3; InterLock on; PowerOnState 0; PowerRetain 0; PulseTime1 145; PulseTime2 1; Pulsetime3 145; SetOption1 1; SetOption26 1; SetOption56 1; SetOption57 1; Restart 1
