Can I calibrate my shutter positions?

Configuration
1

I have window shutters, operated by a Z-Wave.Me ZME_06436. And I hade made automations to open them, close them, or open them to a specific position.

Recently the shutters had a problem and after this was fixed the reported position is no longer accurate.

For example: I had an automation where I put it slighty open at 20%. But it wouldn’t open anymore. Turned out the ‘closed’ position was now about 33% instead of 0%.

Is there a way to fix this? Either in the device configuration or on Home Assistant?

You could wrap your current cover entity in a template cover where you can control what’s considered open or closed.

It seems that your module doesn’t have current measurement, correct? In this case module just assumes end positions, based on time. So, maybe it would help to fully close cover, remove power from module for a minute and re-apply. That way you will reset positions. If it doesn’t help try the same, but with cover fully open.

That’s why i have chosen current-controlled cover module (in my case it’s shelly 2.5, loaded with esphome FW). Such module knows when cover has reached end position, since current stops flowing (end switch is triggered). Thus each fully open or close operation “resets” position.
