I have to agree. Aqara make some excellent hardware, but their Zigbee firmware is typically awful. Their battery-powered switches also drop off the network at random.

I have several E1 wired switches and had to resort to replacing the firmware on them[0]. They don't drop off the network as their sleepy end devices tend to, but they also can't be bound to other devices.
