I’ve the same issue. No idea what I’m doing wrong. I followed the following steps:

Discovered the MAC address using my Android phone (by pairing with the BLE sensor)
Added the below to my configuration
The error logs show that Hassio is unable to retrieve any values from the sensor.
Placed the BLE sensor within 1m of the Raspberry Pi
Restarted the Raspberry Pi

I’m on Hassio 0.71 btw. Do I need to pair the sensor with the Raspberry Pi? Seems unusual that all one needs is the MAC address and voila, you can read the BLE sensor readouts.

sensor:
  - platform: mitemp_bt
    mac: '4C:65:A8:D8:7F:58'
    name: Xiaomi BLE Sensor

using a ble app on android i can see the temp and humid reading so it must just advertise without really having to pair to it

automationpirate · July 28, 2018, 8:12pm

I have had no issues apart from taking over 10 seconds sometimes.
From having a look it seems you don’t need to “pair” it. Once the MAC address is found it should be fine.

With the code (just thinking out loud) does it work if you include the ‘monitored conditions’ even though it’s optional?

Dominic · July 28, 2018, 10:52pm

good idea - didn’t work sadly. are you running the latest hassio build?

automationpirate · July 28, 2018, 11:19pm

Not brave enough for Hassio yet. Still on hassbian.

sebdoan · July 31, 2018, 9:01pm

Hey all, mine is working now. Turns out the bluetooth range between the raspberry pi and the sensor isn’t great. I’ve to have both in the same room to get the sensor data into Hass

loudmicro · August 1, 2018, 8:19am

did you install the BLE addon? I have it working

Dominic · August 1, 2018, 10:05am

no the new hassio blog said don’t install it it’s on by default.

Dominic · August 1, 2018, 10:10am

do you have a link to the ble addon. i can’t find it in the hassio addon lists

loudmicro · August 1, 2018, 12:54pm

Ohhh sorry I’m still on resinOS. if you’re on HassOS you need to keep it disabled

edit: grammar

Hi,

I’m having the same issue… anyone found a solution yet?

Dominic · August 23, 2018, 10:29am

I moved mine closer to my
Pi and rebooted and it’s working

sebdoan · August 25, 2018, 12:41am

Bluetooth range of the raspberry pi isn’t great

Vincent · August 27, 2018, 11:51am

i have nearly the same issue, but i didn’t see any warning in logs.

i have no value received and no warning in log

I have the same error here.

Could it be due the fact, that those sensors are from Aliexpress (region mainland China)? I mean I cant use them in mainland Europe in Android app Mi Home, but I cant successfully use them in region mainland china.

Could be this limitation directly in the firmware of the sensors?

A spark from my log:

I used the config from here:

CZBios · September 11, 2018, 10:18pm

The topic is already discussed here. For Domoticz there is a python script, which by the comments of other looks like, that reading of the sensor can be done. Does it mean, that there is an error in Home Asistant add-on?

Oh man… one of ours is playing up all of a sudden. I put the sensor RIGHT NEXT to the pi but just get the “Polling error Could not read data from Mi Temp sensor”

EDIT: Turns out the program I use to find the Mac address wasn’t showing me the correct one. I had to take the batteries out of all my other devices and then it found it.
Helps when you have the right Mac address huh!

I try this here: Xiaomi Thermostat (with display) - Page 2 - Domoticz

myUser@raspberrypi:~ $ dpkg --status bluez | grep ‘^Version:’
Version: 5.43-2+rpt2+deb9u2

So, if this is still a bug, my 5.43-2 should be a ‘bug-version’.
Then I disable pnat plugin, by editing /etc/bluetooth/main.conf with sudo and add + reboot:

DisablePlugins=pnat

Another problem could just be the low rPi3 antenna. A solution could be to attach sma connector to it:
