OK gents, after spending two hours clearing trees that had fallen across our roads during last night’s ice storm, I was able to make it to the well and discovered the problem with the NCD/Electron board assembly: the Electron had no power, i.e. no LEDs of any kind. The red LED on the relay board showed that it had power from the external transformer, but apparently the Electron was not getting power from that board and, therefore, it exhausted the Li-Po battery.
I brought the Electron home and connected it to my Mac via USB and proved that the Electron appears OK and the red charging LED shows that the battery is now being recharged.
I ran diagnostics against the Electron and got the same results as before (Electron unresponsive but SIM OK), proving that the results of the SIM test are not a valid indication of the status of the cellular link as there clearly was no connection at all.
Current thinking is that there is an issue with the relay board’s ability to communicate with or, at least, to power the Electron.
Note that there is no GSM service at my home so I can’t get the Electron to handshake with the cloud from here, but once the Li-Po is fully charged I’ll take it back to the well, plug it back into the relay board and see if the Electron’s new function can check the relay’s status.
If the Electron cannot communicate with the relay board, would you not conclude that that board went south for some reason? If so, how quickly can I get a replacement?
