Created a Bluetooth script for the FNB58

Took some time this morning to sniff out the Android application with btsnoop/wireshark.

Figured out enough the notification packet to get the main three values of voltage, amperage, and wattage

Hope this helps.

That is pretty cool. Good job.

I do not have any Bluetooth host / dongle to use with Linux, and I always have issues with Bluetooth anyway. I think my meters do have BT support, but i never tested it, even with Android.

From the look at your code, the data format is different, and there are other things that are different of course. But it looks simple and straightforward.

I will test it one day. Maybe it is not that a bad idea, to reduce number of cables.

Do you know what is the frequency of sample updates when using Bluetooth?

Looks to be the same 4 lines per second

07:06:19 - 4 lines per second

Hi,
I try to use your script with my FNB58, unfortunately it receives nothing

python3 ./fnirsi-fnb58.py 
Connected to Bluetooth device.
Wrote value: aa8100f4
Wrote value: aa8200a7
Notifications enabled.

parse_data() is not called.
Any hint ?

It seems related to the USB port in use.
Without USB connection your script works 👍
Thanks for sharing.

Yeah it can't USB and Bluetooth at the same time. Glad you figured it out.
