Does SLWF-01pro module work?

[bokkoman]

Do you think this module works?
It seems like it is made for this kind of stuff already. Though, might have to change something on the pins? Can pins be changed in the code?
I'm very very new to this!

It should only be treated as compatible if you can access the same appliance UART pins.

This project bypasses the original cloud/Wi-Fi dongle and talks directly to the dehumidifier over UART. The example YAML has configurable tx_pin and rx_pin, so the ESP-side GPIOs are not fixed. What matters is the appliance side: TX, RX, GND, power, baud rate, and voltage level.

So if the SLWF-01pro exposes the appliance's UART and you wire it in place of the original dongle, the YAML pins can be adjusted. I would verify the module pinout and logic voltage first; this repo does not speak a separate SLWF cloud protocol.

I ordered one. On the HA forums for this project, someone mentioned it and said it worked.
If it works, it's a great entry level for this project.
