Here's the questions I have:
What weather software will support the Honeywell?
How long has Honeywell been selling weather stations?
After reception is established (all of the remote readings will appear on the main unit’s display), position the remote sensors and the main unit within the effective transmission range of up to 328 feet (100 meters). Ideally they should be placed within the line of sight of the main unit.
I worry a lot about this. Ideally placed line of sight with the main unit? You mean, like in a window? What is the effective range of the device in a real-world situation?
Also, the outside units take lots of AA batteries, all of which need replaced periodically... that's 2 for the rain gauge... 2 for the UV sensor... 2 for the wind gauge (oh yes, the one way up there on the pole)... and 2 for the thermo/hydro sensor.
These are things you want to think about before buying.
