Add device availability functionality for HASS based on router devices ping and attribute reporting also available on battery-powered devices

[ugrug]

• Router devices ping available by set in configuration.yaml: advanced/availability_interval
• Additionally availablitiy of battery-powered devices with attribute reporting possible by listening for incoming messages. For these devices report interval can be set in configuration.yaml: devices/device_ID/attribute_report_interval
• For working ping functionality fixing the callback of the zigbee-stephard/Controller.prototype.checkOnline function needed. Related to this, created a pull request for it. For testing, available at: Fix checkOnline callback zigbee-shepherd#8

Great, could you open the zigbee-shepherd PR here? https://github.com/koenkk/zigbee-shepherd

Thanks 🐝!

@Koenkk It is great you merged this feature! 👍
One question related this: As I see you dropped the availability for battery-powered non-pingable devices based on attribute reporting and required to monitor last_seen attribute to detect availability, possibly configurable per each device with the interval of attribute reporting (configuration.yaml: devices/device_ID/attribute_report_interval). Are you open for this feature?

[Koenkk]

@ugrug we dont need the last seen attribute, I prefer to just keep track of this by handling zigbee messages in the handleZigbeeMessage function. Lets keep extensions as standalone as possible.

I`m still struggeling with the availabillity of battery based devices as we dont really know how often a sensor could report. A good guess would be 1 day, however this is probably not alwys right, perhaps there should be some devive specific option to disable it for that device.

Hi, I'm new to zigbee2mqtt and i find that the availabillity of battery based devices is pretty important especially for some sensors like smoke alarm, water leakage sensor, etc.

I know that different devices will have different report/heartbeat interval. Like @Koenkk just commented, perhaps just make it configurable for each device? Any plan to include this feature? If not, what is the best way to monitor this in home assistant?

Sorry for commenting on the Closed thread. I'm not sure whether this is the correct way to do it.

@waiweng83 the correct place is #775
