Read error: 'device_4'

[jakubcermak]

Hello,
I dont have anything connected to device_4 (the output is blocked in the Jablotron app), however the integration tries to read data from this device and therefore my log is spammed with:
Logger: custom_components.jablotron100 Source: custom_components/jablotron100/jablotron.py:1027 Integration: Jablotron 100 ([documentation](https://github.com/kukulich/home-assistant-jablotron100), [issues](https://github.com/kukulich/home-assistant-jablotron100/issues)) First occurred: 17:57:40 (13 occurrences) Last logged: 19:40:05 Read error: 'device_4'

Also it means that all the sensors are often marked as "unavaiable" for a few seconds, potencially triggering automations. Is it possible to fix this please?

Please try to find the complete log.

Hi, I tried the get enable the diagnostics and I got following stacktrack - is this what you mean?

I'm sorry, I dont know anything about programming for HA, however I added a new log so it logs whole exception and I got this:

Traceback (most recent call last):
File "/config/custom_components/jablotron100/jablotron.py", line 1014, in _read_packets

self._devices_data[device_id][DeviceData.BATTERY] = True
KeyError: 'device_4'

I went through the code and is it possible that the Jablotron unit is somehow sending info about device 4 although it's blocked and according to the technician there is nothing connected to it? I marked it as "Empty" in the JA100 integration, however it seems that the integration is not ignoring the device as it should, instead it tries to save the device info into a dictionary which is not present because the device should be Empty?

Just an idea :-)

Please try version master. I think I've just fixed it.
