Is there a way to tell what the mapping for Tasmota is by looking? I took this picture and am having a lot of difficulty figuring out where the GPIO maps go

check blakadder https://templates.blakadder.com/

check what the other chips are, that will give you an idea whether there is any serial going on, or the tuya chip.

Unfortunately the blakadder site doesn’t have the switch. Here’s the switch in question…can’t find it anywhere.
Weird, how do you turn the fan off? HIGH, MED, LOW. Where is OFF?
Have you identified the chips? Done any tracing?
EDIT the fccid would help. It has an FCC logo, but of course that is just as likely to be a lie
I’ll take the switch off the wall tomorrow to see if I can get the FCCID. But to answer the on/off question, the fan speed buttons are toggles. If you press low, it turns on low, and if you press it again it turns off. Same behavior on any of the three.
I have not done any tracing but since it’s a tuya board I tried the generic tuya template and that allows me to toggle the fan on and off low, but no other buttons work.
Not sure what you mean by “generic tuya template”.
I confirm the chip on your second pic nearest your index finger seems to be a serial chip. It has CR302 written on it and google points to this page https://www.letscontrolit.com/forum/viewtopic.php?f=6&t=3245&sid=aa5026dfa07e27c31de6cf7b1b150434
The other chip, I cannot read the label, so no way of knowing.
As far as the tuya serial chip is concerned, there is docs here https://docs.tuya.com/docDetail?code=K8uhkesnz5mie or you could try the approach here to get some data. https://esphome.io/components/light/tuya.html
So - the first link looks like the ticket, but its focused on ESPHome - is there a way to convert the info from ESPHome to Tasmota? I am trying to move everything to Tasmota if possible, and would rather not have one device that runs ESPHome while the rest run Tasmota if possible…
I posted 4 links, the last one is for tasmota.
Sure enough! Missed the last link. That totally did it for me.
Thanks!
