For what it’s worth, I recently upgraded from a controller 67 to a controller 69 pro plus. At the same time I added a cloudforge T7 humidifier, hookups for my lights, and an aci outlet to control a couple reptile heaters. I only connected the controller via bluetooth because I don’t see the need to connect it to WiFi. Any changes I think of making or issues that fire an alert/alarm will still be there when I get home. Controller firmware is running most current version with no issues during updating.
The only issue I’ve had to date is when the humidifier spit humidifier condensation onto the UIS port of one of the cloudray fans causing the port to “lose its brain” and forget what type of device it was and stop responding to the controller. I do blame their extremely inconsistent messaging regarding humidifier hose routing for my issue. Rerouting the humidifier hose and drying the fan out for a couple days took care of everything though.
Idk. Maybe I waited long enough to get a controller from a later batch that had a lot of issues corrected.
