I would like to see a graph from the other mods that are doing as you say. That is the only true way to see if they are getting a nice even temp. Unfortunately I don't think they have the software . Just because it seems to be working right doesn't mean it's working properly.
Also Evolv is in the middle of moving locations while still running a business. That itself is a very stressful task. They have been on here, they have said the have some updates/fixes, they have said they are working on items and not abandoned anything.
People need to be patient.
