Home Assistant Sensor for the Mijia Temperature Sensor

mitemp_bt's Issues

Issue with Temperature value less than 10degC

Hi,
It appears as if the sensor platform code stops returning values if the temperature is below 10degC. This possibly also affects humidity but I can't verify this.

I'm running Hass.io on a RPI 3 with several of these sensors. The ones above 10degC continue to work normally; only one is dropping below 10deg C and when it does temperature, humidity, and battery values for only this sensor freeze and don't update until temp goes back above 10degC.

Suspect there is a single digit temperature (and humidity) bug in the code? I've never debugged python code before but I'm happy to try and look tonight.

I've had a quick look at the code and this might be the issue:

    # Parse the output
    res = re.search("( [0-9a-fA-F][0-9a-fA-F])+", result)

which is in
def write_readnotif_ble(mac, handle, value, retries=3, timeout=20, adapter=‘hci0’):
and
def read_ble(mac, handle, retries=3, timeout=20, adapter=‘hci0’):

Appears as if it needs to have 2 characters for a result to be found… But if the display is returning a 0 in front this should work. Wondering if the parse of the handle from the sensor (in format 0xXX) is only returning 1 (e.g. 8.3) rather than 2 (e.g. 08.3) characters for the non-decimal part…

Some comments are here with 2 other users with the same issue:

Great work on the sensor code - it was a breeze to get the sensors configured and running. Happy to help with this bug if I can!

Cheers,

Not receiving data

Hi,

so i installed hass.io on a pi3 and added mitemp_bt to my sensors in yaml. Unfortunatelly I only get an "Updating mitemp_bt sensor took longer than the scheduled" for both of my xiaomi sensor.

This is my config:
`sensor:

• platform: yr

• platform: mitemp_bt
  mac: '4c-65-a8-d4-c5-xx'
  name: Living Room Temp
  force_update: false
  median: 3
  monitored_conditions:

  • temperature
  • humidity

• platform: mitemp_bt
  mac: '4c-65-a8-d5-41-xx'
  name: Hall Temp
  force_update: true
  median: 1
  monitored_conditions:

  • temperature
  • humidity`

As you can see, neither false nor true force_update is working. What am I doing wrong?
