Hey -> just wanted to ask you whether you got any traction on ORP sensing? I just recently completed a battery powered ESP32 + Atlas Scientific ORP kit for my bromine hot tub. On wake-from-sleep (power - on), my ORP readings take longer to stabilize in hot-tub water (about 1 minute to 95%), compared to the reference solution ( a few seconds) or the datasheet. Otherwise, measurements from the kit from atlas scientific are pretty awesome!
@mzakharo How did you set up this? And what do U use? Esphome?
No not esphome. esphome is not so great on battery. micropython all the way.

@mzakharo Thanks for your quick reply๐ I'm thinking of building monitoring for my pool. The plan is to mount sensors in a bypass. and monitor orp, ph, temp, environment temp and pump pressure. So i guess some of your hardware will work in ny case ๐ I'm running Home Assistant. And already have a few esphome devices. But i also have mqtt. Guess i'll try with esphome. But have more options at least
@mzakharo Do you measure constantly?
Constant measurement was not an option for me because I dont have power near the tub, and wiring power from the tub's electronics is ....... unwise due to insurance/warranty concerns.
I had to go for a battery powered solution, so the system is in deep sleep for 60 minutes between measurements.
Ok. I have power where I plan to have this. So i guess constant is an option for me ๐
Folks, thanks for your comments and contributions. Life has been a little hectic and I've had my focus elsewhere, forgive me. Over the coming weeks I will respond to each and every one of your comments as well as bring this repo back to life. I have lots to share. ๐ซถ๐ผ
I found some really helpful articles on pool chemistry which pointed me towards the need for an ORP sensor. This will allow me to measure my chlorine levels.
