I have 30+ wall switches 2476D and others, They have been installed for a year or so. I seem to be having switch failures on the switches that are used the most. Tap the switch on or off and nothing happens. My wife and kids are getting very frustrated as I am as well.
If you hold the switch it will turn on or off but it seems a quick tap dosent register. Occasionally they will work fine but mostly not.
I have tried to tap them slower and be more deliberate but some times it takes 7 or 8 tries, I here the switches clicking but no operation. I have reset them and re-programmed them as well But to no avail. I have one now that is just dead (no lights) and another plug in module that is dead too.
I have the Houselink software that I check to make sure there are no dead links and have up loaded the whole database a couple of times too.
It just seem to me the switches are wearing out. I just wanted to post this before I start replacing them. Any help would be appreciated I have about 5 right now that are constant problems.
This is a known problem that can exist on switches manufactuered up until sometime last year (not sure when exactly). The 2 microswitches beneath the paddle can fail independently over time due to oxidation. This can and does occur even if the switches are never used. The good news is supposedly this was fixed in recently manufacturered switches by changing to a different microswitch in the manufacturing process (or maybe the manufactuer of the original microswitch fixed the problem). If your switches are still under warranty, try calling Smarthome and get them to do an RMA to get replacements. There's also a document out there somewhere that shows you how to replace the microswitches yourself, but my understanding is it requires some soldering skills. I wouldn't attempt that on a switch that is still under warranty.
