@StainBase, big thank you! your change perfectly works with new ZMAI-90 based on WB3S (after changing WB3S to esp 12).
For others, who got new ZMAI-90 with WB3S,
you need to:
1) Change WB3S to esp 12.
2) Compile latest tasmota from, (Tasmota 9.3.1 Kenneth, still doesn't support it), future version will be support.
3) Apply, choose module TuyaMCU(54)
And run in console:
Backlog SetOption66 1; TuyaMCU 11,16; TuyaMCU 36,6; TuyaMCU 37,1; SetOption59 1; SetOption72 1
Rule1 on System#Boot do RuleTimer1 10 endon on Rules#Timer=1 do backlog TuyaSend8; RuleTimer1 10 endon
Rule1 1
