smarthome_newbie Posted January 14, 2021 Posted January 14, 2021 PLM power light is not on. Everything is working, but I thought I recall it being on. I unplugged it and it turned on, but once it connected, it turned off again. Is it supposed to be off?

Brian H Posted January 15, 2021 Posted January 15, 2021 Mine is also on solid green. If a dual band module is doing a Communications/Beacon/4Tap test. It may flash green or red. To indicate it is receiving the test signal and on the same or opposite phase of the power lines. What hardware revision is the PLM and its firmware reported in the PLM Info/Status test in the Administrative Console tools?

It doesn't flash red or green. It's just not on at all. It's not a matter of the bulb being burnt out because if I unplug it, it will come on but go off again. Very curious.
Brian H Posted January 15, 2021 Posted January 15, 2021 The hardware revision number is on a white sticker on the back of the PLM. You have to start a communications test from another dual band module. For the LED to flash red or green. Some modules out of RF range may not cause the LED to flash at all. Goes On and then Off is something I am not familiar with. So I looked at the Modem Developers. There is a data bit that can be set in the Set IM Configuration command to turn off Automatic LED operation. Then an LED On or Off command is then needed to turn the LED On and Off. I can't imagine how that could have been set or even if it is the problem.

Seems like other members have had same issue with power light on ISY. Is it worth doing a warranty repair? Just thinking something else could be going on with it.
Geddy Posted January 17, 2021 Posted January 17, 2021 @smarthome_newbie if it's the ISY power light that isn't on then you probably have a faulty power supply or SD card has gone bad. Power supply options: You can try any power supply that outputs anywhere between 5 volt and 30 volts,center positive, 2mm barrel connector Help with replacing SD card: https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Replacing/Formatting_an_SD_Card What happens when you plug it in? Boot up sequence: Power, RX&TX, momentary blink of Memory/RX and TX, and then Power only For power supplies check if you have any old router plugs or cordless phone plugs laying around. Just see if you happen to have anything in the house currently to test with first. If that solves your problem and you need the plug elsewhere then look at ordering one or buying one locally. Good luck! 1
MrBill Posted January 17, 2021 Posted January 17, 2021 @smarthome_newbie My bet is on the power supply. There have been quite a few lately it seems. Note that the voltage requirements are very wide, meaning a wide variety power supplies will work. UDI also sells a 12v 1amp replacement in the store.
Brian H Posted January 17, 2021 Posted January 17, 2021 I too have had a few wall warts fail. On ISY99i and newer ISY994i. I would try a supply and see if things are better. If the ISY994i works correctly but the power LED on it is off. There are a few reports here where the power LED does not light but everything else works 100%.
