Looking for ZigBee or 433MHz soil sensors!

Hello to #HomeAssistant gardeners! I'm unsure what's good right now as far as those go. Smaller sensors are better, not as small as coin cell, and especially if I can get illuminance as a sensor.

Just unsure what to pick. Reviews are mixed on so many options it feels like. Some complain ThirdReality's are too huge, some complain of disconnects.

Right now I've a generic larger ZigBee one and a tiny BLE MiFlora, and open to others.

I use the ecowitt wh51, and they work pretty well. I have the 433mhz ones, but I’m using the ecowitt gateway, and not a rtl usb adapter.

They’re not that small though, but they run off a single AA battery, and the battery life is pretty good. Integrates well with home assistant.
