[SOLVED] Items receive commands but stopped to update their states

The ZigBee binding tries hard to avoid polling - polling is generally not a good thing as it needlessly consumes bandwidth. Both ZigBee and ZWave support systems for reporting change, and that’s what we try and use. Of course some devices don’t support that, and then the binding will fall back to polling, but polling is relatively slow. In general, most devices really should support reporting. If reporting configuration fails, then the binding will poll, but this is a much slower update than …

Zigbee binding disables autoupdate.
This is fine if devices respond promptly to commands with an update.
If that doesn’t work for whatever reason, no state change takes place.
