MiScale 2 time out error about bt-mqtt-gateway HOT 5 CLOSED

I don't have V2 so not sure. Never heard of anyone reported that V2 works with this code. So probably not ?

from bt-mqtt-gateway.

I would like to try and get it to work, maybe that would help others as well.

Just not sure how exactly I would start with that???
I did have a look into the worker file of the xiaomi scale and saw that you are looking for a specific value and then do some math with that.

EDIT: this here is what I was looking at:
https://github.com/zewelor/bt-mqtt-gateway/blob/master/workers/miscale.py#L43-L44

Would you be able to help me with this? Maybe I can find out the bluetooth messages from the scale and maybe you could do the code for it, since I am not good at programing?

Is there a good program or app to capture all the bluetooth content that the scale is sending so I could give that content to you?

Thanks a lot

Hi

I think there is good chance that someone already reversed v2 and protocol is described somewhere. Here is good explaination of reverse process for V1, you can try to recreate that. https://github.com/oliexdev/openScale/wiki/Xiaomi-Bluetooth-Mi-Scale

Code in miscale worker is just copied from some exmplaes, available on the internet. You can take this worker and play with it to get correct weight retrieving procedure for V2.

This repository has been updated with support for the v2 scale. Please update and let us know how it works for you. Closing for now.

Hi,

@bbbenji , thanks for letting me know about the update.
I just tested it (complete new install) and I seem to have a few issues...

EDIT: My old problem with the mqtt not working correctly, it was because the service was still present and active on the raspberry it started the gateway in the background. And me starting it with the normal command made it run twice and that fucked everything up big time.... my bad.

Now I did find a real problem (I think). When you use the scale and either wear socks/shoes (basically anything else apart from bare feet) or you step off the scale after you see the weight before the body measurements, you get the following error from the gateway and it stops!

("Impedance is too high (limit >3000ohm)")

Could this be caught somehow and maybe if someone just steps on the scale for the weight but does not wait for the body measurements, just send out the mqtt messages containing the weight and nothing else.
