David D Posted February 15, 2016 Share Posted February 15, 2016 As stated in a previous thread, I've been tracing some intermittent comm issues and came across a device that was providing good signal strength, but was still giving me an error when I did a "restore device" on the ISY994. I connected my Elk ESM1 at my PLM and had my wife turn the offending device (SwitchLinc Dimmer v.35) on and off while observing the ESM1. I had PLENTY of signal strength (over 2.5 volts) coming from the SwitchLinc as measured at the PLM, however, when I tried to do a "restore device", I got a communication fail error on the ISY admin console. I pulled the air gap switch on the SwitchLinc for about 30 seconds and pushed it back in to reset it. I then tried another "restore device" and it worked that time. My question is, what would cause this to happen to a device that had been working fine for awhile? I have had this happen a few times over the years (I migrated to Insteon starting in 2005), but am perplexed as to why. No known electrical issues that I know of coincided with the problem. Any ideas? David Link to comment Share on other sites More sharing options...
Brian H Posted February 15, 2016 Share Posted February 15, 2016 The electronics in the module could have been scrambled by maybe some line noise or fast power dip and it was not running correctly. Pulling the Air Gap did a power cycle reset and it then was running correctly. Link to comment Share on other sites More sharing options...
