Cannot re-connect to meter

[rdeserm]

When I first set this up it worked great the first time, despite a few disconnections that I think were the fault of PG&E.

Eventually, it got disconnected and since then the utility company has not been able to re-pair my device to the meter.

They recently replaced my meter with a new one, no improvement.

Here is the error log that I'm getting:

I'm curious if anyone has some insight on what could be going on? It would take considerable effort to get the device closer to the meter and it appears that it is getting a "join response" from the meter. I've reinstalled esphome on the device, done hard resets, etc.

Thanks

You need to reflash the old stock emporia firmware onto the device to enable the repairing process. This firmware only asks the zigbee chip to request a reading from an already paired meter.

Reflash the old firmware, repair and amke sure it all works and then reflash this firmware so it can continue reading.

Anybody have a copy of the original firmware? I am having the same issue and not quite sure how to flash back to the stock firmware?

[baudneo]

What version does your MGM chip say it is? I have firmware for mgm v2 and V8. Can also give you the command to flash stock FW.

The command would be great... I will check on the chip when i get home this evening.

Thank you!

In the above log output you can see how it reports MGM version: 2

[13:46:33][I][Vue:503]: MGM Firmware Version: 2

That's what you'll be looking for in the esphome log output.

[dblinick]

It is version 2

One sec for the command. You'll need to install esptool using pip.

[baudneo]

esptool.py --port /dev/ttyUSB0 --chip esp32 -b 115200 write_flash --flash_freq 80m 0x0 {path to file}

you might need to change the --port and obviously change the {path to file}

awesome - thank you!
