Hi IoTa Watt community!
Been enjoying my new IoTaWatt since getting it new a few months ago, amazing device and features! But upon checking my Emoncms stats today I noticed the last update was 26 hrs ago. Upon inspection of the device, it had a solid red light - not a signal mentioned in the support documentation. Tried a few power cycles, but to no avail. Any tips on how to recover the device?
Cheers,
Stew
Solid red isthe same as solid green, except that there is no WiFi connection. So the unit is monitoring and recording data, and will upload when a WiFi connection is restored.
Check your router to see if it is working properly.
If you power cycle the IoTaWatt, the LED should blink red-green-green for three minutes before turning solid red. During that three minutes, it is in AP mode and you can connect to it as in the documentation for a new unit. When you connect you can see the WiFi networks that are available, select one and provide the password.
Thank you for your reply.
I can confirm the SSID I use for my IoT network was available and everything else on the same SSID was connected OK.
The light was solid red immediately after power-on. I just opened the box up and re-seated the SD card, and everything has come good. Bit weird, but glad it is working again.
Weird isn’t a technical term I subscribe to. SD issues should manifest with specific LED codes. If your Emoncms recovered with data from the solid red period, it wasn’t the SD card. Could you post the message log so I can see what might have happened?
Emoncms is missing the data.
Here is the message log - note it was 5/06/20 17:54:56 when I re-seated the SD card and tried again.

Thanks. I can see that your PVoutput stopped on the 5th at 2:35pm and resumed on the 6th at 5:55 for about 35 minutes, then nothing until today (your time) at 10:40am. So something happened around 6:30pm yesterday to stop again.
You say you power cycled several times during the downtime, and that there is no record of that in the log does indicate that the SDcard was probably not working. That said, checking the SDcard is one of the first things iot does at startup, and there are specific LED sequences to indicate problems. So I’m not so much puzzled by an SDcard issue as I am a possible failure to detect it and produce a diagnostic LED sequence. The Serial output would have provided more information, but that’s not a field diagnostic.
If you continue to have problems, please check back in as I would like to get to the bottom of this if it happens again. Thanks again and sorry you lost a day’s worth of monitoring.
