- Home Assistant (very basic user, only use it to control some MQTT tasmota flashed relays with my phone)
- Matrix server
- InfluxDB+Grafana for collecting various metrics (server usage, temperature sensor, hooked up to serial port of smart electricity meter for power and gas usage graphs)
- WireGuard for remote access, obviously
- Many other random stuff and my own projects
