Mini split adapter (minisplitcontroladapters)

Has anyone used this device for controlling their mini split with a smart thermostat? EDIT: Removed link because it is dead and goes to a sketchy site now.

I am tempted to try this with my daikin system, but was hopefull that someone else here had already tried it out. It seems like a good solution for us mini split users that don’t have a good option (if it works).

Ok, if nobody has tried this, does anyone have an opinion on if this is a good idea? Or better alternatives?

Yes I have them installed in my system and they do work great but just dealing with Jeff the owner is an issue
