Where will you read the measurements?
An included console, a phone app and a local network interface are different ways to read a station. Check what works without internet and what needs additional software or an account.
Can the sensors go where you need them?
A separate rain collector can be placed independently from the wind sensor. An integrated array shares one location. Check the mounting instructions, signal path and power rather than inferring suitability from a radio-range claim.
What remains included after a trial ends?
Separate local readings, standard cloud access, paid history or alerts, and optional hardware. A trial does not establish permanent premium access, and a consumer API does not establish commercial data rights.
