Thanks for sharing. Do you have experience with them and the Ha integration?
Not OP, but I use these to monitor my plants. I use a HackRF and the following software to collect the data.

It works okay: it drops around 10% of the data due to reception issues, but I think it might be related the parameters I have set for the gain on the software defined radio.
