Your thermostat tells you about the hallway. It doesn't tell you about the nursery. Every house has rooms that don't match the rest of it — the corner bedroom, the room over the garage, the nursery you keep checking on with the back of your hand. One reading from a hallway thermostat can't tell you about any of them. The RuuviTag Pro 3in1 measures the room it's actually in. Mount it on the wall with the included bracket and it reads temperature to within a tenth of a degree, with humidity alongside it. Open the app and the numbers are there — no hub to buy first, no wiring to run, no subscription to see your own data. BUILT FOR MORE THAN A BEDROOM The IP67-rated enclosure and a battery rated from −40 °C to +85 °C are why the same sensor turns up in greenhouses, garages, crawlspaces and boats. In a nursery, that engineering just means a small matte-black device that keeps working and stays out of the way. One coin cell runs it for a year or two. It also stores ten days of readings on board, so a few days out of Bluetooth range won't leave a gap in your history.
