I’m experiencing a similar problem but may be more related to the weak wifi signal – not sure.
I get frequent packet loss (on average about 30%) to both opengarage devices and, more importantly, timeouts from Home Assistant polling which really messes with automation (e.g. it doesn’t know if the state changed legitimately or was just a result of loss of connectivity).
Is there any way to rig up an antenna to the device to increase wifi reception and/or influence the responsiveness to requests from the network?
