hardware compatibility

[jerome6994]

good evening
a question are the NUT mini, Nut Find 3, Tile, somfy badge compatible with bt2mqtt?
Thank you

Hi

There is generic ble scanner worker. Probably you can use it: https://github.com/zewelor/bt-mqtt-gateway/blob/master/workers/blescanmulti.py

It seems to give a few things but in my test I have 2 nut find 3 and I only see one on MQTT Explorer

When I do
sudo ./gateway.py

I have an error on the opening of the serial port ttyUSB0 that I cannot correct

Afterwards, during the deployment I change the path for the user

Then when I run the service I get this error again

So when restarting my VM there will no longer be the active service

thanks a lot for your help

[zewelor]

In workers section of the config, leave only blescanmulti worker, delete everything else, if you don't want to use it ( you probably don't need anything else for now ).

[jerome6994]

sorry for the formatting of the code block there must be symbols in it badly recognized

yes I deleted or commented everything for future use like Miscale

on the other hand I do not understand the errors related to the serial port and the service which does not want to remain active.
if my VM is stopped and restart I lose bt2mqtt and I have to restart by hand

[zewelor]

serial port is used AFAIK only by mysensors worker, from pasted config, looks like you got it still on. Delete it and it should run

[jerome6994]

Hello
Indeed I left my sensor
Removing more error is better :)
However, I can't get the service to activate.

[zewelor]

Run it without service to get full logs.

[jerome6994]

I launched this
sudo ./gateway.py -d

[zewelor]

Looks good. Not sure why service version doesn't start. I think you could try to add "-d" on the end of this line, maybe it will show some error: https://github.com/zewelor/bt-mqtt-gateway/blob/master/bt-mqtt-gateway.service#L9.

EDIT: Or maybe this: https://unix.stackexchange.com/questions/225401/how-to-see-full-log-from-systemctl-status-service

[jerome6994]

I started all over again I have this command which gives me

[zewelor]

You probably missed this step:

sudo pip3 install -r requirements.txt

Also I would suggest try docker router, as it should be easier to work with and maintain.

[jerome6994]

good evening
I ordered it, it's weird!

I can't make it despite the advice
docker I don't have at all I only have VMs
behind this test I want to implement the solution on several pi zero to mesh the house better

[zewelor]

I've looked at venv instructions and fixed them a bit. I'm not using this method so don't have much experience. If you want to mesh home with some bluetooth tags to see where is someone etc. I would recommend use some esp32 board with software like https://esphome.io/ or https://tasmota.github.io/docs/ or maybe something like this: https://home-assistant-guide.com/2021/09/09/is-espresense-the-successor-to-esp32-mqtt-room-weve-been-waiting-for/. Having few rpi zero is a headache to support them in long run. You got whole linux system running + possible problems with sdcard wearing after a lot of writes ( unless you configure os as read only ).

I would go with esphome route, you can probably use it with mqtt only without Home Assistant even.
