433mhz soil moisture sensor

Hardware

Hi there,

I am looking for a 433mhz soil/moisture sensor.
I found this:


but apparently it is limited by maximum 3 sensors you can have (they have a switch to allow up to 3 channels).

I would prefer to avoid miFlora as 433mhz coverage is much better

Did you ever get this working?

I am also looking at the same soil sensor.

Listening on 433MHz with my rtl-sdr, I am picking up one of my neighbours Opus-XT300. Could easily be sent to HA via mqtt.
