ATC_MiThermometer VS BorgBackup

I want to do a little IOT project where I establish a MQQT-Broker on my Raspberry Pi and send it readings from my measurement devices (xiaomi Mijia-LYWSD03MMC). The plan is for these devices to connect to my ESP32, allowing me to transfer data to the broker on the Pi. I've successfully connected my ESP32 to my Wi-Fi and to my broker, but I'm experiencing significant difficulties in connecting it to my two measurement devices. I have essentially followed the instructions provided in this GitHub repository (https://github.com/atc1441/ATC_MiThermometer) as best as I could. I also checked some other repos but they didn't really help me as they were too big/complex...

If you get off WiFi and on Bluetooth: https://github.com/atc1441/ATC_MiThermometer They last a year with a single CR2032 which is hard to do with WiFi.

I then copied this Python script to the Raspberry Pi 4 and was able to read the temperature and humidity! (https://github.com/atc1441/ATC_MiThermometer/tree/master/contrib/python)

I’m using 16pcs Xiaomi Thermometer LYWSD03MMC BLE thermometer around the house with custom ROM from here https://github.com/atc1441/ATC_MiThermometer

I use the Xiaomi (pronounced Show Me) Mi Temperature and Humidity monitors (version 2) and flash the firmware with a 'open source' version (here or the older one here). I've found battery life good (8 months + with the newer software on one sensor) and bar from one corrupt display (right next to an outdoor electricity feed - well the box is handy and dry) then they have just run and run and run.

The thermometers in screenshot are Xiaomi Thermometer LYWSD03MMC with ATC custom firmware. Their bluetooth broadcast data collected by some cheap chinese ESP32 board and ESPHome addon in Home Assistant.

You can replace their firmware with one which is more open and broadcasts the values without needing to connect to the device: https://github.com/atc1441/ATC_MiThermometer

i use - and recommend - "borgbackup": for example with the "vorta" graphical frontend

just my 0.02€

I used this many, many years ago but switched to Borg[0] about five years ago. Duplicity required full backups with incremental deltas, which meant my backups ended up using too much disk space. Borg lets you prune older backups at will, because of chunk tracking and deduplication there is no such thing as an incremental backup.

Currently, I'm auto-backing it up with borg (push mode) through wireguard tunnel to NAS behind ISP's CGNAT. The borg takes care of deduplication in SQL file, so incremental update (even in append-only mode) is very small for PostgreSQL dump.

Borg 2 has been in development for nearly a year and a half [1] and may probably be released early next year, i.e., early 2024 (just a guess, seeing that even RC1 is not yet released and seems to have a lot of work to be done).

Does anyone know how Borg 1.x and 2 would compare to Kopia?

You could use borgbackup.
