LC Tech 4CH Relay Board Tasmota?
Here is a video of how I got my 4 CH LC Tech relay board working. This relay board has been running my AC (see other videos in my channel) for 6 months, and has been 100% stable.
*Update: Here is the link to the nightly builds, there does not seem to be an official release yet.

*Update 2: A comment posted on this video shows how to set up Tasmota to work with the LC Tech relay, I have not tested this method, but likely this is a more stable alternative as wespota is only available as a nightly release at this point.
Tasmota doesn’t support it yet, but Wespota does. Wespota so far has been working great and operates just like Tasmota.
