2.10.0

When zigbee2mqtt reports a device offline, the plugin turns it red in Indigo so you and any plugin watching for failed devices can see it. That red could vanish within ten minutes while the device was still dead, because other updates the plugin writes to the device, such as its network counters, were clearing it. The red now stays until zigbee2mqtt hears from the device again, and nothing else about what the plugin shows has changed.
