Sensor 'unknown_devices' only increases but never decreases

[basstp]

After a recent update of ha-edgeos (i sadly don't know which version i was using previously), the sensor 'unknown_devices' does not decrease any more.

Details

When a DHCP lease is given out, the sensor increases as it should (for example from 0 to 1). When the client leaves the network the sensor however stays at 1 and does not go back to 0. This is also true with multiple devices (the sensor goes from 1 to 2, but never back to 1). I can however get the sensor back to the correct value by reloading the integration.

Currently using ha-edgeos 2.1.7, my edgerouter x is at version 2.0.9-hotfix.7

I already tried reinstalling ha-edgeos via HACS but that did not seem to help.

Debug logs

I poked around in the debug logs and found that the info seems to be retrieved correctly from the edgerouter, but the sensor 'unknown_devices' doesnt update correctly.

Here are some snippets from the debug log. I initially had 0 clients connected, then 1 client:

When the client disconnects I now should have 0 clients again, but the sensor still thinks the client is there:

(I have replaced my MAC address and hostname with *** for privacy reasons.) You can see that the information is retrieved correctly:

• leased changes from 1 back to 0
• the client is no longer listed in dhcp-leases
• dhcp-server-leases changes from 1 back to 0

However the sensor.edgerouterx_unknown_devices still shows the client.

I hove I have given enough information to hunt down this bug. Thanks! :)

Same issue I'm having. Glad I'm not the only one.
