My PWS is KALBIRMI288. I see 274 but not 288 in the app.
Seems you have a Gen 3 Rachio, or Gen 2 from Costco, Your weather underground station was setup recently (June 4th?) and may not yet be available on the Rachio map. Often times it takes about a week for the new station to show up. Meanwhile you can leave the setting on the WI+ profile to automatically choose the best station in your area. Check back next week and see if you can see your new station on the map.
