I’ve replaces a few capacitors and repaired a few electronics over the years, so I should be able to handle adding pins.
Was going to ask which unit you were working on. I have two of the standard AC units running in a couple locations.
Really looking forward to adding this capability to the open sprinkler units running greenhouses. This capability is going to make me even stronger proponent of OpenSprinkler on some of the vegetable and grower forums and groups that I’m involved in. This really fills a capability gap for small greenhouse vegetable growers.
