I ordered 4 without the temp probes and they all arrived in good condition within a couple of days. The set up instructions were clear and I had readings from my 4 houseplants within an hour of unpacking the box. I do worry a bit about the open hole in the sensor, so I will water carefully. It will be a learning curve to understand how much water to add when they are dry, as there is of course a lag of about 1-2 minutes before the moisture level updates in Home Assistant. I suggest making the illuminance sensor at the end of a lead like the temp probes, because houseplants can often be in deep pots where the soil is well below the rim, so reporting the illuminance deep in a pot isn’t useful. Being able to clip the sensor within the foliage would provide a more meaningful measure of a plant’s light exposure during the day and allow me to better position if needed. But overall, I have high hope that this little device will help my plants and I’m glad to have them.

Capable and accurate sensor, i just wish it was watetproof

PLT-1 Ultimate Plant Sensor For Home Assistant

Couldn't wait to try the PLT1.
Easy to set up and has more sensors than I thought.
Great addition for my Plants.
Apollo Knocked another one out of the park.
Check it out !

I've found that the moisture tracking is very accurate, and the sensor also measures other vital stats for plant health - amount of sunlight, humidity, soil temp, etc. What's more, it's very customizable and you can have it on 24/7 with wired power, or battery operated and set to wake at user-defined intervals.
