We came home yesterday after three weeks away to find that any Insteon/eisy based automation in the house was not working while any z-wave/eisy items were doing fine.
Diagnosing today the 2413U usb plm had no led activity. Unplugging it and plugging in had no impact on the status LED. Always dead. Looking at it from within the admin consol the PLM showed as not connected. All physical connections appeared fine. I restarted the eisy to be sure. Ditto checked connections. No joy.
As I had a spare 2413U for just such an occasion I have started the process to replace the one PLM with the other. This is solving the problem as now, once updated appropriately, the Insteon devices can be controlled and thus the automation actually working. Tentative conclusion, the original 2413U plm failed.
My two questions:
1) My ISY 994 + serial PLM worked without issue for years. Decades perhaps. So long and successfully that I often forgot the details of accessing the admin console as I rarely needed it despite having a ton of automations in play. I only migrated to the eisy reluctantly, albeit understanding the logic behind why, a few months ago. Talking the opportunity to change to the USB PLM. Everything has worked fine for several months. Now I've apparently had my first PLM failure, ever. This seems suspicious since I'm relatively new at eisy. So, question : Did my diagnosis seem correct or have I been extreme in replacing the PLM ? i.e bad luck or bad diagnosis ?
2) Since I've only lasted a few months without a PLM failure, I am thinking I need a keep alive notification to warn me when the eisy and plm are not communicating and/or the plm has failed. I use the UDI mobile app. How would one recommend I do this ?
Thank you for any thoughts, Peter
