Yeah, the range is definitely not anywhere near what is claimed. I’ve got a 14 foot long hall, which one Hive sensor, placed above a door at one end, used to comfortably cover. With the P1 I had to get one for each end of the hallway because each sensor only seems to cover about 6 feet.
I’m actually wondering whether it’s an issue with the placement of the sensor in the device - I’ve got both sensors mounted above doors and I’m wondering if maybe they would have a better range if they were lower down (or fixed where they are, but upside down so the sensor was at the bottom). The actual sensor seems quite small, and with the extended chin on the device to fit the double battery maybe it’s more restricted on what it can see, so to speak.
