Revamped the water distance measurement setup. A cheap HC-SR04 turned out to be more reliable once mounted in a dedicated spot with no interference. Not waterproof but that will do. had to stay conservative in power: low voltage causes bad readings. Learned a lot along the way.
Finished soldering of garden sensors (water tank temperature and height) => LoRa => home assistant integration where I can see how much water remains and trigger well pump. Electronics ready. Got to finish prototyping all 3D print objects and solar panel power to figure out now.

biggest challenge of the circuit was to properly manage the current surge that the servo needs, it would easily reboot otherwise, it needs a good alim and proper accumulator and mosfet. nice to learn it the hard way
Revamping my home made esp32 tibetan clock driver. 6 months later, re-code-vibed a new firmware from zero with pio, it's 10 times faster with Claude Code. smooth Home Assistant integration. (the thing is a bit far from wifi tho)
