Intergrators and Outputs randomly stopped working

Support

Hi,

Can I please have some help with the integrators and outputs that stopped working?

My outputs “Grid_Export” and “Grid_Import” have started reporting 0W when my house is definitely using energy. They used to work, and I haven’t opened iotawatt.local since before the data stopped so I hadn’t changed a thing.

  • I’ve tried restarting a few times.
  • My IoTaWatt is genuine from the IoTaWatt shop. It was from the batch with the bad SD card, but I’ve already replaced the card.
  • My message log hasn’t had anything new since 2023 for some reason. I’m not sure why.
  • Home Assistant shows that the data stopped around the 19th of August, and on the 19th and 18th there were some unrealistically high peaks. However, when I try to look that far back using my IoTaWatt’s Graph+, I can’t see any data from before

Config
Note that solar is 0W because I don’t have solar yet. The CT is sitting there waiting.

My best guess is that your SDcard is defective. When you replaced it, did you do a clean build or copy files from the old card?

I’m not sure but I think I at least copied the config file.

Could this be related to why the integrator and outputs suddenly stopped working last month? But I replaced the SD card so long ago so I’m not sure why.

Without a message log I can only guess, but given that the message log is maintained on the SDcard and you don’t have any current entries, I would start there.

Thanks overeasy

I added a new SD card with a brand new config and it worked for several days. But then it stopped with the LED flashing red.

Since my PC freezes when I try to read from the SD card, I’m guessing the card is corrupt.

I’m buying another card to try a third time.

What do you think of these ‘high endurance’ cards? Or do you have any other recommendations?

Hi overeasy,

I copied the files from the Github SD Directory onto a fresh SD card that’s never been used, and installed it in the IoTaWatt.
I didn’t copy over anything from the previous card.

However, it reconnected to my wifi without me telling it how.
As expected, none of the inputs, outputs or integrators are set up. But is this still a good fresh start that will help me eliminate the SD card as the problem? The IoTaWatt must have the WIFI details stored on the ESP, but I’m not sure how much else it remembers.

Correct. The ESP EEPROM. There is hardware manufacturing data about some of the components. There is also a copy of the last valid configuration before the current config on the SDcard. If you have made any updates to the config it has probably been overwritten.
