The hardware is based on Tuya's ESP8285 based TYW-E2S WI-FI module, documented in
https://docs.tuya.com/en/hardware/WiFi-module/wifi-e2s-module.html
(in the same website you find documentation for TYW-E1S and TYW-E3S as well)
Unfortunately the TYM-E2S does not expose GPIO0 on the edge connector. This pin is required to be strapped to ground to put the ESP8266/85 in bootstrap mode.
There is a test pad on the back of the device, that needs to be temporary shorted to ground during programming. The other required pins are all available on the edge connector on the side with VCC and GND.
Note that once the espurna firmware is onboard, updates and changes can be done with the OTA feature of the firmware without phisically accessing the device again.
The switches are mapped as follows:
- Switch 1 - socket closest to the power cord
- Switch 2 -
- Switch 3 -
- Switch 4 - socket closest to the USB connectors
- Switch 5 - powers/unpowers the USB power supply
The button does not command any of the relays, but it is active on extended/double click keypresses (reboot/reset to factory settings etc).
