I've been idly browsing for a home weather station for a while, hoping to contribute to the local sensor network for a region that's got lots of microclimate variation. I saw this one from Seeed Studio today, and was hoping for some reviews and advice. Seeed Studio devices are known for open source software, and I wouldn't mind playing with writing a tie-in for sprinkler system automation so we're not irrigating when it's about to rain. It wouldn't be situated so far from the house that we'd need to use the LoRaWAN feature, though.
Concurrently, we just had an inch of rain dropped on our house in the space of 15 minutes, with winds that were taking down tree branches. The weather report says "light rain", weather stations a mile away continue to indicate that everything is bone dry with quiet air. This rainstorm breaks a nearly month-long drought. I'm finding it nerve-wracking that climate change makes it impossible to use past local weather as a predictor of what to expect for gardening, home maintenance, and outdoor activities, and local weather reports are so inaccurate. So that's (hopefully) where the weather station might come into play.
That being said, any chat about your local conditions and reporting from your station is welcome.
