Which scale do you have exactly?
Mi Smart Scale 1 / Mi Smart Scale 2 do not send impedance. (Xiaomi XMTZC01HM, XMTZC04HM)
Mi Body Composition Scale 2 / Mi Body Fat Scale do send impedance.(Xiaomi XMTZC02HM, XMTZC05HM, NUN4049CN)
It’s the body composition scale 2, XMTZC05HM. The app works and calculates the impedance based metrics. Any idea what might be going on?
No, no idea. Does it work in BLE monitor?
I don’t use BLE monitor. I use Esphome. I was able to change the defaults there to limit the risk of missing the value:
esp32_ble_tracker:
scan_parameters:
# default is 320ms:
interval: 80ms
# default is 30ms:
window: 60ms
Hi @e-raser . Did you manage to find a solution? I have a similar setup to you, and cannot figure it out. Any help will be appreciated.
In this topic - which started looking to integrate another Bluetooth device - I also try to get the Mi Scale weight as sensor:
As long as it is not available for the native Bluetooth integration, this would be fine for me.
In case anyone benefits from this (BLE (data coming in unsorted) > split by user > BodyMiScale (one device for each users)), if You want to have 2 or more users You can create two sensor templates like this and just fill in the correct one based on the weight:
- platform: template
sensors:
filtered_weight_andris:
friendly_name: "Filtered weight Andris"
unit_of_measurement: "kg"
value_template: >
{{ states.sensor.ble_weight_mi_scale2.state if ((states.sensor.ble_weight_mi_scale2.state) | int) > 68 }}
- platform: template
sensors:
filtered_impedance_andris:
friendly_name: "Filtered inpedance Andris"
unit_of_measurement: "Ω"
value_template: >
{{ states.sensor.ble_impedance_mi_scale2.state if ((states.sensor.ble_weight_mi_scale2.state) | int) > 68 }}
- platform: template
sensors:
filtered_weight_niki:
friendly_name: "Filtered weight Niki"
unit_of_measurement: "kg"
value_template: >
{{ states.sensor.ble_weight_mi_scale2.state if ((states.sensor.ble_weight_mi_scale2.state) | int) < 68 }}
- platform: template
sensors:
filtered_impedance_niki:
friendly_name: "Filtered inpedance Niki"
unit_of_measurement: "Ω"
value_template: >
{{ states.sensor.ble_impedance_mi_scale2.state if ((states.sensor.ble_weight_mi_scale2.state) | int) < 68 }}
So I just have the Passive BLE monitor providing me the above weight and impedance values which I turn into two template sensors each (based on above or below 68), which in return are used as the weight and imp. source for the BodyMyScale integration (so the resulting 2x2 entries become the data feed of the BodyMiScale).

Some extra info on where to put that code would be welcomed.
do we put that into sensors.yaml?
in configuration.yaml?
do we have to alter something in bodymiscale?
I put it in configuration.yaml.
No altering is needed.
BodyMiScale requires a weight and an impedance sensor value to work. Normally You would add the sensor data (weight/impedance) coming from the BLE sensor. But if You create (with the above code) 2 template sensors (just like the original), then You basically mimic the BLE output, You create two pairs of very similar sensors. These template sensors can then provide the input to two MiBodyScale instances. See here:
As You can see I added 2 services and I am NOT using the BLE sensor output for weight and impedance (at least not directly), but the template sensors I created with the above code.
I hope this helps.
Thanks for answering man. I have it working a couple of days now but it gets errors in the logs sometimes and also it is like this is not a real sensor somehow. Like its a float that get erased after restart.

I am trying to get the new sensor way of home assistant and not the legacy one.

But i get this error.
Configuration warnings
Invalid config for 'sensor' at configuration.yaml, line 12: required key 'platform' not provided
Hey GnF, I will not be able to help You with so deep tech, I did not check myself if I have errors as long as it works reliable (my system is running now for 4 years, so I have a lot of misconfigs). However as far as I am understanding what we are doing the sensor being reseted at restart is normal (as its just a template being filled out by its input when it arrives), but I think there should be a way to make it non volatile. Sorry that I can not help You further.

I did try to use else return to 0 if it does not have a measure or if it looses data but it does not work ok. I will keep trying.
So the above again does not work very well.
Lets say user one and two.
User one uses the scale and all filtered sensors update normaly. Also the card for that user is working.
User two uses the scale and all is well.
If after a day or two user one has not use the scale but user two is keep using it then the card for user two is working normally but the card for user one says unavailable.
Damn
Since the data are stored in a time based db maybe the data from user one are now old? And this integration does not see them?
I have to find a way to keep updating the filtered value on the new sensors on the time even if there are no new data. Damn
Hopefully someone can help me here…
I´ve successfully configured the integration through BLE, and the first weigh-in shows up correctly. But I just cant get it to update with new values when i´m weighing myself again. The Zepp Life app registers new weight but nothing is updated in HA…
Why is this? There´s no error logs either
The signal strength is: -73 dBm. Maybe thats the issue? But the scale is 3 meters away from my raspberry pi
Make sure to keep standing on the scale until the weight-display has switched itself off again.
did that, twice, also restarted HA. No change 
Zepp Life registers the changes
Be careful, you cannot be on the Zepp application at the same time.

Dont know what fixed it. I “reinstalled” the Bluetooth integration, then opened the integration and clicked on configure and checked “passive scanning”. Cant say if I had this enabled before.
Having the Zepp app open does, in fact, hinder the information to be sent to HA.
I dont have to wait for the display to switch off. Its enough if I wait until the measurment-bar is fully complete.
Is this still the case?
Meanwhile I integrated it using OMG.
But having it natively with plain „Bluetooth on HA“ would be an improvement.
