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.
I got some from Ali Express. They seem ok for the price. Dirt moisture and air temp and humidity. Dual AAA though so kind of large.
Just checking the HA forums is this guy https://community.home-assistant.io/t/soil-humidity-sensor-433mhz-decode/202335
I have the whoffset AQI that has worked well, and I’m always looking to expand lol
@bravesilvernest Dang, was hoping it’d play nice with the RFlink style boxes, the fact I’d need a dedicated RTL for it (that doesn’t overheat either, had that issue) is a bit oof. But I’ll keep it in mind. I’ve also seen that exact form factor in ZigBee.
Tbh, I read both 433 & 908 on the same box and just switch every 10s :)
Have a look on yoochoob for “the guy with the Swiss accent” (I forgot his real account name) - he did an interesting article on soil sensors.
I bought a zigbee sensor off Ali Express and it’s fine, but it’s waaay to.big for a small pot plant, but fine for a large one… so “big” vs “small” is kinda relative to the plant you’re monitoring.

Thst’s the guy!
Thanks.
@KayOhtie @homeassistant I saw a few custom ones on Tindie that looked nice and affordable. Havent made the purchase just yet.
