Tom, For more than a year my weewx Modbus Energy Monitor driver/service (mben) runned without any problems. The archive interval was set to 60 seconds and the report interval was set to 5 minutes. Configuration: raspberry PI 3B+, raspbian stretch, weewx 3.9.1, python 2.
After I upgraded to weewx 4.0.0b16 with python 3 mben can't run on time anymore. In an earlier message I already mentioned the numerous debug log messages the modbus section produced with 'logging'.. These messages were suppressed in a way you suggested. The 4.0.0b16 logging below show that mben can't keep up in time even when the archive period is set to 300 seconds. The last log message says: Mar 25 07:08:00 pi31 mben[484] INFO weewx.manager: Added record 2020-03-25 06:45:00 -03 (1585129500) to database 'weewx_mben31' So in one hour the program is already 23 minutes behind. The only difference in the mben code is the logging which was set to module logging instead of syslog for weewx 4.0.0b16. I can't tell why mben is so much slower in 4.0.0b16. Maybe the logging, maybe something else. I went back today to weewx 3.9.2, python 2 and 60 s archive interval and syslog debug messages (instead of logging) and everything is back to normal. I know, you are not familiar with my mben driver/service and the pymodbus package and also I don't expect a solution. This message is for your information only.
