IKEA Fyrtur blind going haywire

Anyone had the problem where the blind goes haywire? Mine operates as you’d expect for months then randomly stops responding to controls from HA. I believe reinserting the battery fixes it but I’m not sure.

The other day, it unwound itself and didn’t stop past the limit and so wrapped itself up the wrong way. I was baffled as it’s never done this before.

At the moment the only thing working is manual control.

Are you using the IKEA tradfri integration or have you integrated the blinds manually with ZHA or Deconz?
In any case, did you update the blinds to the latest firmware version?

Just using zigbee2mqtt - I don’t have an ikea hub so I don’t think I can use the tradfri integration?

not using zigbee2mqtt - couldn’t get it to work
