I have a personal weather station; it's an Ecowitt GW-1104 installed at my place in the Shinn neighborhood of Fremont, CA. The data gets exported to my website; it can also be accessed via Amazon Alexa, Apple HomeKit, and I've also posted the acculumated data to my website in a couple different ways.

The Alexa skill is Caphector's Weather Station. Asking Alexa about the temperature provides current temperature, a basic forecast, and the daily high/low. Asking about the weather will read out the temperature response and also provide humidity, dew point, barometric pressure, rain, and wind speed. The skill can be be invoked with:

Alexa, ask weather station about the temperature

Alexa, ask weather station about the weather

Alexa, ask weather station about the humidity

HomeKit uses a Siri Shortcut; it can be installed from from Apple's iCloud. This shortcut will provide current temperature, a basic forecast, and the daily high/low (forecast data from Aeris Weather). It can be invoked with:

Hey siri, weather

Weather Data Center has forecast data from Open Weathermap, tide forecasts for where Alameda Creek empties into San Francisco Bay, and a variety of graphs showing current and historical conditions.
The Belchertown skin has forecast data from AerisWeather, a more compact information display, and a different variety of graphs showing current and historical conditionss.



I built an Sky camera to have a record of sky conditions. It uploads a sky photo once every 90 seconds or so. It genrates time lapses showing the sky each day and night, tries to generate composite star trail images, and keograms which are kind of a sky state summary.
