Oh boy. Which version of the stove?
And, You’re in luck. Its all spelled out here in gory, technicolor technospeak:
The story of my journey over the past year and all my trials and tribulations of conquering this frigging stove.
If you’re willing to be a little bit adventurous, I’ve rewritten major parts of the firmware while keeping all the safety protections of the stock unit, and you can do the same. Mine has been burning now all day and night for a week without going out once and regulates the room temp perfectly. Minimal pellet use (maybe 3/4 bag a day) and the glass is completely clear as opposed to covered in soot. It only took me a year to get here, but is working flawlessly.
The factory programming on these stoves is absolute CRAP. Some of the worst embedded control system code Ive ever seen. These stoves are anything BUT smart. It’s what you get with cheap Chinese slave labor and cost cutting manufacturing and products rushed to market. However, these stoves are all in good company. Most brands these days are all built in China and suffer from many of the same limitations and problems. So, you get over it and brute force fix it.
The good news is that all changes with my mods. You get complete control over all functions including fire pot burn control if you go all the way. Or, just replace the wifi chip firmware and use ESPHome. That at least gives you all the correct display controls in home assistant which you can then run automations against.
Step #1 - if you’re uncomfortable jumping in full hog right away, call the support number and tell them you’re wifi module stopped working. it worked for a day, now no response. its been that way for a month, but the stove has been working ok. Now the igniter doest work and that’s why I’m calling. You want them to send you a new Display unit and a new igniter. You igniter will burn out in a year. Trust me on this!
Then you put my basic ESPHome code into the wifi module and you have full home assistant integration. It replicates the display in all user mode functions LOCALLY. No more Chinese controlled Tuya cloud.
Honestly, Ive programmed 5 of these wifi modules at this point and if your ok soldering the small pins on the TYWE1s chip, you can’t really screw it up. the chips are almost bulletproof. meaning there’s not much that can brick or fry them. all the pins are gpio signal level, so shorting them has no effect, AND they don’t do anything. That chip is ONLY there for wifi control, literally NOTHING else. in fact, you can take it out and the stove functions fine, you just have no wifi control.
Step #2 - modify the controller board (it has all the wires running to it at the bottom of the stove) by cutting ONE trace and running 2 new wires to the display unit. And then you have a truly SMART Pellet Stove.
Optional: if you don’t have a WiFi board in your Pellet Stove and it looks like the pics on my GitHub, my mods allow you to use pretty much ANY ESP8266 or ESP32 and it gives you control over all display functions.
Use the discussions section or problems section in GitHub to ask me anything. I know these stoves better now than anyone in tech support at Cleaveland Ironworks, and you can take that to the bank!!
