Your pain tolerance is clearly way higher than mine! I really do have a drawer full of the 433 gear, and achieved some very rudimentary comms going years ago using a pair of arduinos sitting next to each other on the desk, but quickly abandoned it. I'm impressed that you've achieved what you have using this gear - and equal parts impressed / distressed that you use a CRO to get there. I also have a tipping rain gauge, but I expect to wire it up to an ESP32 too - as the Hall effect doesn't care about 3v3 or 5v : ) And yes, rainfall models in my (rural) part of the world are poorly documented - but public transport systems are even further distant than official weather stations. For some of my (few hundred metres from a power point) needs, very low power is a pre-req, but pricing now for LoRa, PVC panels, batteries, etc, means even that becomes orders of magnitude simpler to solve by NOT trying to scrimp on a few hundred mA.
