Hi Rxich,
This driver currently does not support this solar-powered alarm, it is rather different than the other Tuya alarm/siren devices.... I will try to add at least the basic alarm on/off function in the next driver update,
This is a bit disappointing, are you sure the device stays connected to your hub Zigbee network? You may need to pair it again, using the Double luck vodoo.
Is there a way to switch the power off and then power the device back on? Or, as it is solar-powered with built-in accumulators there is no way to cut off the power?
