Let's Control It

Hi all,
These generic wall thermostats seem to be widely available, such as Ebay.
I've just got one to try out.
There's an ESP-12 with just TX, RX, GPIO15, EN, VCC, GND connected.
A PIC16F1947 microprocessor to drive the LCD screen.
5 touch-sensitive areas on the screen.
Holes for a 5 pin header: RESET, VCC, GND, SDA, SCK.
And a temperature sensor.

I'm guessing that the ESP12 doesn't do much more than send/receive Wifi app commands.
It powers up by connecting 3V3 to the header holes.

Has anyone else tried these?

Any pointer to help us?

Hi, Flying Domotic,
Nothing to report yet regards controlling it, but it seems this is a Tuya-compliant device that can the controlled from one of the Tuya apps.
I'm now looking at using one of the Python libraries to control it.

I mean: if you give us a pointer (or at least the brand) to the device you're trying to work with, someone can tell you if he/she already tested it.
As of now, we only know that you've found a Wifi Smart Thermostat on eBay, where there's lot of them

Ah!
It's unbranded, but works correctly with the blue SmartLife app.
Perhaps they are all Tuya standard, but try to get you to use their own app instead?
Mine wants you to use "Smart RM"

Could you post a link to the device?

Without knowing the comms protocol between the ESP and the PIC I don't think it will be possible to replace the ESP's firmware.
Plan B is to use a Python library, now that I've managed to get the device's 'localKey'

Why don't just contact the manufacturer about the wish of having ESP Easy working with their hardware. We only need to know the communication and we'd be able to add it as a plugin. You'd be surprised over how well willingly many companies are.
