Hi! I believe I’m having the same issues you were or similar situation. I believe I have the same tort table and I’m thinking of getting plexiglass cut for the lid too (for heat and humidity). How did you attach it to your lid?It's controlled by a custom built thermostat and relay, that can't be remotely controlled and alarms to the phone. I posted some pics of it here.
Also I haven’t been using the hide side yet with my baby thinking I’d give him a little one and later on give him a bigger house. Haha. But I can’t get my humidity right and am trying to find out if I can use that side for the humid hide even though it’s wood. Then I need it warm too. Did the RHP work for you and was it hard to setup?
