## Questions & Answers

**Q: Can these be connected to an automated sprinkler system for a lawn? It would seem a fantastic idea!**
A: I think there's the possibility but it's not direct. Ecowitt products will send data feeds to Weather Underground. Weather underground can then connect to ITTT. If your sprinklers are ITTT compatible for on/off then with a bit of research and the right script. It should be possible.

**Q: Can these stay in the soil year round to monitor my garden? Or are they popped in to take a reading then removed**
A: they are popped in to take a reading then removed, it needs the betteries

**Q: Can I connect multiple sensors to one gateway?**
A: Yes, I have two soil moisture sensors on one gateway. Works well.

**Q: Can these be left in the ground all year round?**
A: In winter, the soil hardens and damages the sensors

### ⭐⭐⭐⭐ Works but poor range
*by J***Y on 18 July 2025*

I bought this to complement my Ecowitt weather station and several other sensors. I noticed that this sensor has a much shorter range than my other sensors and I had to move my gateway for it to pick up the signal. After that, it works fine and gives readings that seem plausible. Time will tell how good the battery life is.
