I loaded the suggested engine.py and now there is only a record saved every 5 minutes:

Which value is used for the 5-minute-storage? An average or the latest? Or is the WMR200 pulled once every 5 minutes? There is still quite a busy log here: Nov 5 22:37:14 RPi3_L5E weewx[25497]: wmr200: MainThread: D Queuing live packet rx:53 live_queue_len:1 Nov 5 22:37:14 RPi3_L5E weewx[25497]: wmr200: MainThread: D genLoop() Yielding live queued packet id:56 Nov 5 22:37:14 RPi3_L5E weewx[25497]: wmr200: MainThread: D Queuing live packet rx:54 live_queue_len:1 Nov 5 22:37:15 RPi3_L5E weewx[25497]: wmr200: MainThread: D genLoop() Yielding live queued packet id:57 Nov 5 22:37:15 RPi3_L5E weewx[25497]: wmr200: MainThread: D Queuing live packet rx:55 live_queue_len:1 Nov 5 22:37:16 RPi3_L5E weewx[25497]: wmr200: MainThread: D genLoop() Yielding live queued packet id:58 Nov 5 22:37:16 RPi3_L5E weewx[25497]: wmr200: MainThread: D adjust_rain rain_total:31.90 Rain.rain_total_last:31.90 rain_interval:0.00 Nov 5 22:37:16 RPi3_L5E weewx[25497]: wmr200: MainThread: D Queuing live packet rx:56 live_queue_len:1 -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
