Disconnecting every 11 sec

[smarthomepch]

Hi, first of all thanks for this. I have it run on my RPi 4 and everything works fine so far :)

Now I try to run it also on RPi Zero W and for some reasons connection to MQTT broker restarts every 11 seconds:

MQTT broker is on another RPi4 (3rd one (!))

As mentioned another connection works fine.

BTW is there any possibity to add IP and MAC addresses per interface (I think both are part of psutil)?

Thanks in advance for help.

You need to change mqtt_clientid parameter in the psmqtt.conf to something else. I guess I need to make it dynamic eventually.

Agree, will implement it when I have free time

Thanks for prompt answer. After mqtt_clientid change everything works fine.

One more thing. Seems that virtual_memory/free/{{x|MB}} is wrongly calculated. Shoudn't Free memory + Used emory be equal to Total memory?

Used and Total memory look OK.

I appreciate :)

You can check docs here https://psutil.readthedocs.io/en/latest/#psutil.virtual_memory

free: memory not being used at all (zeroed) that is readily available; note that this doesn’t reflect the actual memory available (use available instead). total - used does not necessarily match free.

Thanks!
