I run a setup with 3 weewx instances reading from two different GW2000, update Intervall 10 seconds. There can be different readings, because the devices aren't queried at the same time. The shorter the interval, the less likely you will recognize those differences. Graham Eddy schrieb am Samstag, 16. November 2024 um 07:54:01 UTC+1:
