Mopeka Pro Check BLE Sensor

The mopeka_pro_check sensor platform lets you track the output of Mopeka Pro Check LP, Mopeka Pro Plus, Mopeka Pro Universal or Lippert Propane Tank Sensors, Bluetooth Low Energy devices using the ESP32 Bluetooth Low Energy Tracker Hub. This component will track the tank level, distance, temperature, and battery percentage of a device every time the sensor sends out a BLE broadcast.


This sensor component only supports the following sensors:
  • Mopeka Pro Check devices

  • Mopeka Pro Plus devices

  • Mopeka Pro Check Universal Sensor

  • Lippert Propane Tank Sensor, part number 2021130655

Sensors are calibrated for propane only.

See Mopeka Standard Check BLE Sensor for original Mopeka Check sensors support.


Mopeka Pro Check LP over BLE.


Lippert™ Propane Tank Sensor

The original Mopeka Check sensors are not supported.

Mopeka Pro Check LP over BLE:


  # Example using 20lb vertical propane tank.
  - platform: mopeka_pro_check
    mac_address: XX:XX:XX:XX:XX:XX
    tank_type: 20LB_V
        name: "Propane test temp"
        name: "Propane test level"
        name: "Propane test distance"
        name: "Propane test battery level"

  # Custom example - user defined empty / full points
  - platform: mopeka_pro_check
    mac_address: XX:XX:XX:XX:XX:XX
    tank_type: CUSTOM
    custom_distance_full: 40cm
    custom_distance_empty: 10mm
        name: "Propane c test temp"
        name: "Propane c test level"
        name: "Propane c test distance"
        name: "Propane c test battery level"

Configuration variables:

  • mac_address (Required, MAC Address): The MAC address of the Mopeka/Lippert device.

  • tank_type (Required): The tank type the sensor is measuring. See below.

  • custom_distance_full (Optional): distance sensor will read when it should be considered full (100%). This is only used when tank_type = CUSTOM

  • custom_distance_empty (Optional): distance sensor will read when it should be considered empty (0%). This is only used when tank_type = CUSTOM

  • level (Optional): The percentage of full for the tank sensor

  • distance (Optional): The raw distance/depth of the liquid for the sensor in mm.

  • temperature (Optional): The information for the temperature sensor. This temperature is on the sensor and is not calibrated to ambient temperature.

  • battery_level (Optional): The information for the battery percentage sensor. Sensor uses a standard CR2032 battery.

Tank Types

Currently supported Tank types are:

  • 20LB_V - 20 LB vertical tank

  • 30LB_V - 30 LB vertical tank

  • 40LB_V - 40 LB vertical tank

  • EUROPE_6KG - 6kg vertical tank

  • EUROPE_11KG - 11kg vertical tank

  • EUROPE_14KG - 14kg vertical tank

  • CUSTOM - Allows you to define your own full and empty points

Setting Up Devices

To set up the sensor devices you first need to find the MAC Address so that ESPHome can identify it. First, create a simple configuration with the esp32_ble_tracker and the mopeka_ble component like so:



After uploading, the ESP32 will immediately try to scan for BLE devices. Press and hold the sync button for it to be identified. Or alternativly set the configuration flag show_sensors_without_sync: true to see all devices. For all sensors found the mopeka_ble component will print a message like this one:

[20:43:26][I][mopeka_ble:074]: MOPEKA PRO (NRF52) SENSOR FOUND: XX:XX:XX:XX:XX:XX

Then just copy the address (XX:XX:XX:XX:XX:XX) into a new sensor.mopeka_pro_check platform entry like in the configuration example at the top.


The ESPHome Mopeka Pro Check BLE component listens passively to packets the Mopeka/Lippert device sends by itself. ESPHome therefore has no impact on the battery life of the device.
