My Own Wifi Upgrade Journey from Australia

[ctessel]

Somehow, no idea how, I stumbled across this and you got me excited. I live in Australia and this type of wifi controller is sold in the local pellet heaters we have here. These pellet heaters come from China and use the "Smart Stove" app to control them. Like another thread here, this is my journey from complete wtf is this to hopefully flashing and not frying anything. Bought myself a CH340G and will begin going down the rabbit hole to see what I manage to fry. Ultimately aiming for the D1 mini because well I can? Again, seriously thank you for this. Seems amazing and I love tweaking stuff. Pics below:

Well, based on what you've shown, my mods should work. You really cant "fry" anything if you're careful. and the stove will work just fine w/out the wifi module installed.
As you can tell, there's a lot of time I've put into this. you can take the KiCad files and have circuit boards made now, if you go that far.

Yes, the more I read and slowly understand I can see the immense work over the last few years you've put into this. Question. Do you still have any circuit boards for sale? I see the link to your site but not sure. As I'm in Australia I'd like to combine a few for shipping, so curious if you have any left and how many. I see one post you said you had five etc. Thanks.

[jazzmonger]

I do, I think I have 1 or 2 left. what might be cheaper than me shipping from the USA is to upload the Gerbers and order them from JLCPCB. You'e get 5 for $5 and cheap shipping from china.

I have the same model and app. Jusr confirming, I should be able to flash ESPhome to the original chip as well right?

[jazzmonger]

Yup. Direct replacement for the Tuya crap.
my “advanced mods” requires an ESP32 all with board and cpu board mods, but the basic TYWE1S replacement code remains the same and can be done in the Tuya Chip if you’re careful and patient.

Use this configuration file:
