Fischb22,
I think you have just solved your on problem. you either have a worn out receptacle in that location or a poor connection attached to that receptacle in that room. If you aren't electrically challenged turn off the circuit breaker to that receptacle and check and/or replace that receptacle. If when you plug something into that receptacle and the plug feels loose in the receptacle the receptacle is badly worn and should be replaced. If on the other hand the plug feels firm in the receptacle it could be a loose connection on one of the wires supplying power to that receptacle. Remove the receptacle cover plate, remove the receptacle from the wall box, and check how the wires are connected to the receptacle. If the wires are just plugged into the back of the receptacle use a very small screw driver and release them. Form the wire into a semicircle loop and secure them under the screws on the side of the receptacle. Replace the receptacle in the wall box, replace the receptacle cover, and turn the circuit breaker back on. Now firmly place the module into the receptacle and I think you will notice a noticeable improvement in the operation of the module.
From your description of your problem I almost guarantee it is a loose connection in electric feeding this receptacle. I too have a CM19A and it does a wonderful job of controlling everything in my system. It controls flawlessly, I wish I could say the same for the CM15A.
Let me know if this helps.
Till Later,
Bob
