I’ve had a Vallhorn PIR sensor for a few months. It’s been working reasonably well until this week, when it stopped reporting Occupancy events. The Occupancy state would vary between “Unknown” and “Cleared”, whereas previously it was reporting “Detected” when it was triggered.
I deleted it from my Zigbee2MQTT config, and finally managed to re-pair it (after 20-30 attempts and a few changes of battery). It now reports Availability as “online” in the Z2M console, but all sensors in HA are reporting “unknown”.
My coordinator is an SMSLight SLZB06.
I also randomly got this error from the Z2M console - I don’t know if it’s connected:
Other devices connected to this coordinator are still working fine (including one in close proximity to the Vallhorn), so I don’t think there’s a problem with the coordinator itself.
Any ideas for how I might be able to revive the Vallhorn?
