Nortek HUSBZB-1 shows sometimes as offline #392

Open JMan7777 opened 3 years ago

JMan7777 commented 3 years ago

Hello,

my ZigBee stick Nortek HUSBZB-1 shows sometimes as offline even it is my Coordinator. How can it be that the Coordinator is shown as offline even the communication with all my other devices works fine?

Device info

EZSP = Silicon Labs EmberZNet protocol: Elelabs, HUSBZB-1, Telegesis by ZHA

FYI: I upgraded the Nortek HUSBZB-1 firmware some time ago, so it should have a recent firmware (I think I put v6.3 on it).

This is my setup:

Version | 2021.1.5 Installation Type | Home Assistant OS Development | false Supervisor | true Docker | true Virtual Environment | false Python Version | 3.8.7 Operating System Family | Linux Operating System Version | 5.4.79-v8 CPU Architecture | aarch64

Host Operating System | Home Assistant OS 5.10 Update Channel | stable Supervisor Version | 2021.01.7 Docker Version | 19.03.13 Disk Total | 219.4 GB Disk Used | 19.3 GB Healthy | true Supported | true Board | rpi4-64 Supervisor API | ok Version API | ok Installed Add-ons | Samba share (9.3.0), SSH & Web Terminal (7.8.0), Let's Encrypt (4.11.0), File editor (5.2.0), Glances (0.10.0), InfluxDB (4.0.1), Grafana (6.0.0), APC UPS Daemon (1.9), Home Assistant Google Drive Backup (0.103.1)

I seeing the same phenomene with my "Billy EZSP" have RSSI N/A and LQI 255 all the time and being lazy to updating last seen in device card and ZHA-Network-Card. Its always being flagged online after the last seen is being updated. It was 05:13 and being updated 09:15 so its around 4 hours. Then the coordinator is one "normal" router with trustcenter i think the last seen is coming from then ZHA is doing the magic network scan (reading the neighbor table in all routers) tha shall happening in intervall 3-4 hours. Was doing one "ZHA_MAP.scan_now" from ZHA services at 09:26 and the last seen and the network card was updated to last seen to 09:26.

I seeing its some "personality" of the EZSP coordinators but its looking little not so nice on the device card. network-map, ZigZag and ZHA-Network Visualization.

you can disregard it being shown as offline. The actual device for coordinator is a fake device and sometimes ZHA is missinterpreting it's status, because it behaves very differently from every other device.

@Adminiuga Ok, I can understand that the coordinator is just a fake device. But even so, shouldn't the coordinator only show as offline when the related hardware device (in my case Nortek HUSBZB-1) is not available or not responding. In case the coordinator is functional it should be always show as online.

The main reason I created this issue is, that I want to react when one of my ZigBee devices goes offline. So the offline state will be a trigger for me. I have some smoke sensors which from time to time drop off the ZigBee network and I need to pair them manually again. Because of that I created an automation which informs me when a specific sensor drops out the network.

So even the coordinator is just a fake device it still should have the right status all the time.

When device is marked offline, zha sends an event. Listen to that event

Understand but nevertheless the coordinator should never go offline unless some problem with it.

Yeah, it's a bug.
