What's New in Zasder Weather

2.5.1

September 29, 2026

Nearby stations, a forecast corrected by your own yard, leak alerts and a watering call. • Nearby stations: compare your readings with up to three Weather Underground stations within 25 km, drawn as dashed lines on Charts. Needs your WU key. Nothing is fetched until you open the nearby row. • Sensor drift check: when your station runs consistently away from its neighbours, Charts says which sensor and the likely cause, such as a radiation shield in the sun. • Your yard's forecast: where the forecast has been missing your station by a degree or more, each day shows a YARD high and low beside the forecast's own numbers. • Next few hours here: one line under the current conditions combines incoming rain, your station's own trend and today's forecast high. • Watering call: water, go light, or skip, from a week of your own rain against evaporation. Also sent to your webhooks every morning for irrigation automations. • Leak alerts: Ecowitt leak detectors alert when wet and again when dry, and show on the dashboard and the watch face. • A 24 hour record for every station, now at the bottom of the Today card, including stations that send from your own network. Hours the service was down are marked as the service's. • Storms, compared: the storm report shows the same storm at each of your stations, and storm cards show how far the temperature fell and how the dew point changed. • Sensor channels: extra temperature and humidity sensors on channels 1 to 4 get their own card. • Sensor checks: the Stations page shows which readings were rejected as impossible over 30 days, per sensor. • Rules that repeat a built-in watch offer to turn themselves off, with how often they fired together. • Import coverage: the import page shows which years and months you already have. • Map location: City now places your station at your real town's centre, or choose a spot yourself within 100 miles. • Apple Watch: tap a reading on the face to open its chart, and Ultra shows a 24 hour temperature card. The station name moves to the top bar and charts open faster. • Smart Stack: the watch and widget stacks bring Zasder forward during a warning, nearby lightning or rain. • iPad: a wide window shows your stations beside the forecast, sun and map. • The forecast strip opens on today; tap another day for its written forecast. • Self-hosted servers: Settings shows the right way to update your server, including a one-tap request for Docker and home installs that opt in. • Fixes: the pressure word agrees with its arrow, soil temperatures round correctly, large CSV imports no longer run out of memory, and the widget station picker loads faster. Some new features require the free 2.5 server update in Settings. The app remains compatible with 2.4 servers.
