I received my Controller 4 today and have run in to a few issues. Everything that has plugged directly in to the controller (ie - water level sensor, temp, ph probe, ato pump) worked flawlessly. I had issues connecting to the single plug and the power strip (following online instructions and prompts in the app) but now the unit is doing the following. The app is unable to connect and the unit just continues to do this. There is very little information out there and as far as I can tell the information available at CoralVue does not cover this.
