Cover Roller Blinds - Sevolino/Sonoff-Tasmota GitHub Wiki

I’ve only tested on Dual, but should work for 4CH as well.
setoption22 1 turns on Cover mode
pulsetimeN sets open/close time required for relays N and N+1
pulsetimeX sets the gap and/or start time for movement (mine is 2 seconds), where X is the number of pairs + cover number
NOTE: pulsetime for covers is ALWAYS seconds (and not the scale used by arendst – ie 13 is 13 seconds)
IE for a 4CH, pulsetime1 is open/close time for first pair
pulsetime3 is the gap/start time for first pair.

so for my Dual and windw windows I have
setoption22 1
pulsetime1 23
pulsetime2 2

use the command
cover X
where X is ON, OFF or percentage open (5-100%)
cover 0 thru 4 are reserved as follows
0 – OFF
1 – ON (100%)
2 – Toggle between open/stop/close/stop (ie single switch)
3 – immediate stop
4 – immediate stop and set position to 0 (closed)
NOTE: You can also use a negative offset.
If you do it means turn off all relays and set position as absolute value
ie cover -50 will turn off relays and state position is 50%
NOTE: If you set STATETEXT1 to CLOSE and STATETEXT2 to OPEN, you can also use OPEN/Close as commands

Hope this all makes sense
