Getting online state

[toorisrael]

Hi.
Is there a way I can locally get zigbee smart plug online/offline state?
I've got internet router, zigbee gateway, home servers etc connected to UPS, what I wanna achieve is getting info if there is power outage. But even if smart plug is disconnected from power source, gateway is returning cached device status.

I don't think so. One of the power saving features of Zigbee is it only transmits when changing states, so the gateway has no way of knowing when a plug drops offline. If it's been offline for a while you might see the CID disappear from the list returned by gw.subdev_query().

But somehow tuya api knows device is offline

I think you will see that for any device that fails to report in to the Tuya Cloud. I don't know what "offline" duration actually activates that. Or are you talking about something else?

In that case gw.subdev_query() should return the online/offline status.

It seems subdev_query doesn't work correctly with my gatewary (lidl/silvercest). If I understand it correctly, it should return list of all devices paired with gateway, but it returns only one or none:

gw = tinytuya.Device(config.gatewayid, address=None, local_key=config.localkey, persist=True, version=3.3)
print(gw.subdev_query())

{'dps': {'101': -10}, 'cid': 'a4c1384c4a22880d', 't': 1737100622}
