h1. Esphome
{{>toc}}
h2. TTGO T-Journal
The T-journal is able to communicate the battery state over i2c. After bridging the pads as shown in the picter the IP5306 that is used is connected to pins 13 (scl) and 14 (sda).

If you are unable to program:
python -m esptool --chip esp32 --port COM5 --baud 115200 --after hard_reset erase_flash
and if even that doesn't solve it:
python -m esptool --port COM5 write_flash_status --non-volatile 0
h2. p1 dsmr power meter with TTGO T7 v1.3 mini
I'm using a TTGO T7 v1.3 mini with and end of a phone cable with an RJ11 connector. I soldered the cable connections direct to the board.

On RJ11, pin 1 and pin 6 are not connected / available
