@NotMyBub I make use of the #Ecowitt ones which are RF433 compatible (and also compatible with Ecowitt base stations). I've also heard of Xiaomi Mi Flora Bluetooth soil sensors being very good when paired with an #ESPHome#BTProxy but I personally haven't tried them.
@fmartingr I recently did this with an #ESPHome#BTProxy and I was honestly surprised at how smooth it was. And the best part was that I only needed to do it once, because after that I could flash it OTA.
