Nice board

Board itself looks well made and works as expected.
Converting to Tasmota took more time than expected, so leaving some tips for others
Somehow Wemos didn't get into flashing mode automatically, so I used serial flasher and had to ground D3 while connecting power, to get into flash mode.
Tasmota does not PCF8574A out of the box, so need to compile your own binary - https://tasmota.github.io/docs/PCF8574/ Issue is that default driver does not support I2C address of 0x27, so need to change xdrv_28_pcf8574.ino for yourself. There are multiple ways this can be achieved, I changed '7' to '8' in line 114 to include 0x27 into scan - https://github.com/arendst/Tasmota/blob/development/tasmota/tasmota_xdrv_driver/xdrv_28_pcf8574.ino#L114
Once you get custom firmware onto the device, use Generic module type, set D1- SCL, D2 - SDA and after a restart, you should get the "Configure PCF8574" page mentioned in the documentation. Had to check the "Invert Ports" checkbox for 'normal' operation.

High-quality relay module

A very high-quality product. Everything is very well soldered. Relays from a well-known reputable company (this is not a Chinese factory). The parcel arrived very quickly. Documentation and bundled program work great. I am delighted because I have been looking for such a well-made module for a long time.
