Diesel Heater KingDownload

Which heaters work

Most Bluetooth diesel heaters. Diesel Heater King connects to the heater's own Bluetooth, with no extra box and no cables, and knows a heater by its Bluetooth, not by its brand or model. New heaters usually just work.

How it knows your heater

  • When you add a heater, the app reads how its Bluetooth is laid out, then asks it for its status. Nothing else is sent until the app understands the answer.
  • Some heaters are Beta: the app shows their readings first, and its controls work once you check them against the heater's own panel. See Beta heaters.

How to check yours

  1. Turn the heater on at its panel, and close any other app connected to it: only one phone or app can connect at a time.
  2. In Diesel Heater King, tap Add heater.
  3. The app checks the heater. If it can't read it yet, it says so, and nothing is sent to it.
  4. No heater with you? Try the Demo Heater first.

Yours doesn't connect?

Tap Copy details for support in the app and paste them into the support form: that's all we need to add it.

Not planned

Wi-Fi bridges, wired add-ons and 433 MHz remotes: the app is Bluetooth only, with no extra hardware.

Bluetooth thermometers (Pro, Beta) Beta

King Thermostat can hold the room on a Bluetooth thermometer. The app only listens to the thermometer's broadcasts: it never pairs with it or connects to it. These work today, all in Beta:

  • Govee: H5051, H5052, H5071, H5072, H5074, H5075, H5100 to H5106, H5108, H5110, H5129, H5140, H5174, H5177, H5178 and H5179
  • ThermoPro: the TP35x and TP39x thermometers
  • SwitchBot: Meter, Meter Plus, Indoor/Outdoor Thermo-Hygrometer, Meter Pro and Meter Pro CO2
  • Xiaomi: LYWSD03MMC and other Xiaomi thermometers running the open ATC or pvvx firmware (stock Xiaomi firmware locks its readings, so the app can't read it)
  • BTHome: any sensor that broadcasts BTHome v2 without encryption

Some Govee models send a beacon signal that Android hides from apps that don't use location; if yours never shows up, that's the likely reason. To add one: Room temperature → Add a thermometer, with the thermometer close by. More in Room temperature.
