Shelly 2.5: Rollo broken

[BETEP-ok]

Good Day, gentlemen.

got the following problem since yesterday.

Given: Shelly 2.5 with latest FW and Homekit patch installed according to the manual. Switch mode set to "roller shutter" and calibration made. Shelly succesfully added to Home App.

When: testing various positions of the blinds, and application of Shelly in different scenarios like

• good night - set Blinds to particular percentage of close
• ask Siri to Open or Close the blinds
• manually set the blinds all the way up, down or make minor adjustments

Then: got the blinds broken. dont wanty to go UP or Down anymore. even with a phisical switch like bofore. The motor makes crackling sounds like smth is broken.

Hypothesys:

Homekit doesn't work well with Shelly and this custom FW - not getting feedback about blinds position fast enough. and thus - could be sending simultaneous signals to open AND close the blinds at the same time causing the motor to get corrupted (like pushing up and down buttons at the same time) or maybe I was too persistent while trying to make single percentage adjustments and that cause the same effect. or maybe when i told siri to OPEN the blinds 100% it got them 100% closed, but shelly was sending a different command at that very moment.

Dont know.

Fact is - now there is something broken in the motor and I`ll have to cut the wall to repair ((( (DYI building report pending if you are curious ))

Fix proposal: make sure that the opposite signals are ALWAYS being sent sequentially - never together (this is crucial) and always the new command being executed at least 0.5 seconds after the previous one (otherwise blinds going down with full momentum will break plastic gears as soon as the command UP comes from the Shelly- there should always be a 0.5 sec moment to STOP in between)
