The complete guide
Ambient Weather WS-2902: your own weather station, online
The WS-2902 rewards a careful install; get the array sited and online and it becomes your own published weather station.
Mount the array in the open
Fix the sensor array level on a pole, clear of walls, fences and trees. Sheltered wind and funnelled rain are the two things that spoil the data, so height and openness matter more than convenience.
Get it on WiFi and the network
Join the console to your 2.4 GHz WiFi and register a free Ambient Weather Network account. That's what unlocks phone access from anywhere, community maps and the Alexa, Google and IFTTT links.
Keep the sensor fed and clear
The array is solar-powered, but fit the AAA backup cells for winter, and each season clear leaves from the rain funnel and wipe the solar panel so wind, rain and UV keep reading true.
