I don’t think this is too gnarly but I ingest 433MHz/MHz RF blasts from the neighborhood using a software-defined radio.

I primarily use this to track my 30+ plants using cheaper, lower power, pairing-free and more reliable RF ping-based soil sensors.

I dooo get pager alerts about my potted plants tho.



Are there any reliable, but low cost soil sensors? Most of the ones I've seen are surrounded by complaints of corrosion and premature death.


I use the ecowitt wh51’s that has gone for $15-$20.

Have had a bunch of them for 1-2 years and they all look brand new and I haven’t swapped any batt.

I don’t use the hub.
