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 have the ecowitt wh51, directly with rtl_433.
It's the 866 version.
I had to set rtl_433 to also monitor 866, but other than that, it's been very solid for...Blimey, years now.
