events triggered twice for Wireless switch (2-key) - TS0021 on 2.0.0

[wjansenw]

What happened?

Since I moved to 2.0.0, and started to use the events, I see strange behavuour:

• when zigbee2mqtt container is started, everything works as expected. Single button, double button: it works OK.
• after a while, zigbee2mqtt sends the events to HA twice

logs after a restart of the container (my button is called button_1, and I'm pressing the 2nd button once - this might make it a bit hard to read)

logs after having the container active for a while:

Thank you Dude! It helps also on ikea tardif (I couldn't update since 1.42 z2m because of double click)

I think I am having the same problem but it does not just send the command twice, it sends it 3-4 times each time i click currently

@wjansenw could you provide the debug log of this?

See this on how to enable debug logging.

I would love to - but when I do it now; I don't seem to get this behaviour...
Anyway, I have activated debug and will monitor. I do not use the button that often and the logs have rotated due to some restarts. I will disable rotate to make sure I do not miss the logs if it happens again.

I'm now wondering if it could be because of a router that is unresponsive from time to time. When I was testing, the button was close to that router. Now it is close to another router.
Will see what happens if I can test it close to the malfunctioning router.
