Please understand, as has been pointed out by others in this forum, my tests only answered (for me) one basic question:
Are the water sensors Zwave LR made by Zooz better or worse (in terms of distance) than the corresponding water sensors made by YoLink ?
As other have stated (correctly), this doesn't mean that all Zwave LR is inferior in terms of distance to LoRa.
For the application use case I have in mind, I'm planning to use YoLink devices. I'm also planning to use a Hubitat Hub for other reasons that will interface with YoLink.
It's not ideal, but "it is what it is".
