Hey. I bought Diesel heater from Vevor brand and with disappointment realized the protocol used differs from common protocol used in Chinese heaters.
Because no solution was that time available, I started investigating and created my project.
Right now, with great certainty I can read Chamber temperature, Input voltage, input current, state and fan speed. There are many other things related with glow plug, but right now I cant assign them to proper values (and actually I dont really care).
Once there will need to run the heater on and off remotely, I will finish this part of state machine and then it could be used as complex working component.
@zatakon This is amazing work!! I was just exploring adding a diesel heater to my garage and I was hoping for a way to interface with it in HA! Thank you so much for sharing. I’ll be implementing this soon.
Is there certain models of Vevor heaters that I should look at to make sure this works with it?
With me the same problem, but since I am not good at electrical engineering and do not know anything about resistance, I have practised BLE reverse engineering and have made a lot of things work. Maybe someone else has other ideas and we can complete it together. @zatakon where exactly did you connect the ESP? Directly on the motherboard?
To @ Knutnoh. I see you’ve changed something in the yaml code in the last few hours. Could you please include what you changed in the readme? I’ve already compiled the previous yaml. I can’t test it because I’m waiting for the Bluetooth driver for Vevor. I’d like to know what changed in the configuration. Regards.
I can’t add or compile any devices on ESPHome 2025.9.3. I keep getting these errors:

It’s a framework bug, and it’s best to use chatgpt to troubleshoot the issue. It could also be related to your esp32 board. The YAML needs to be adapted to your hardware and possibly your esphome version. I’m sure chatgpt can help you.
My 2Kw Vevor dieselheater didn’t work with the yaml files posted above. I found the Bruciatore_BLE project that did work.
I translated some italian names and changed my esp32 to the esp32-c6 I’m using. Build with the latest ESP home builder.
Please write or provide a link to a Vevor model that has a BLE driver.
I have a Vevor device, but my device has a standard BT driver, and your projects don’t work.
My driver only has three wires.
I’d like to buy a model that has a BLE module.
Hello. Sorry for not answering, this topic was “on hold” for a while - it worked for me and I was overloaded by other stuff.
I transfered the project into something what should be much easier to use, if you are interested please visit that https://github.com/zatakon/esphome-vevor-heater
Please related issues place in the github, I will try to process them
This way ESP32 can be connected instead original control unit. So far it does not have physical buttons and display, but I would like to implement that in couple of weeks (I would say days but I know my optimistic time estimates.
I need help with my Vevor Heater.
I currently have the yaml uploaded from GitHub:
This is actually the only partially working example:
I can turn the heater on, but not off.
I can change between Level and Automatic.
I can set the heater level.
I can set the heater temperature.
And that’s it. The other parameters don’t match at all. It shows complete nonsense, as you can see in the screenshot.
I’m also attaching a few screenshots I took with the nrfConnect app.
How do I find and match the correct data to my Vevor?
I’d appreciate your help again.
Best regards.
