just recently I am having some serious issues. First I have an open house with mostly ungrounded wiring. I have found it I use more than the one transceiver in the house the remotes work better, my house code is A but I also use B and C to control other parts of the house including the outside and garage. So about a week ago my transceiver on C decided it didn't want to re commands from any remote controls. Then about a day later my main transceiver which is on the house code A decided to start turning on and off about every 30 min. and also around this time and appliance module decided it wanted to do the same (A-3). I am also using a USB transceiver on the computer so I tried disconnecting the Main A transceiver thinking there was a conflict but that did not help anything at all. I also have another transceiver on A in another part of the house which was also doing the same thing, on and off, so I removed it temporarily and again it did not know anything. This is not the first time I have had issues like remotes not working or sporadic operations but it is the first time it has lasted this long.
