Hi, If you are using a Davis Vantage station and the crt extension is bound to loop then you should be seeing realtime.txt being generated every 2.5 odd seconds. If you have changed the binding to archive then based on the weewx.conf extract you provided it should be generated every 5minutes. I am not sure where the one minute update you mention comes from, it should not be happening. How are you checking how often realtime.txt is generated? Are you checking the file on the WeeWX machine or are you checking on a web server or some other server? If you are checking on a machine other than the WeeWX machine remember that there must be some mechanism to transfer realtime.txt from the WeeWX machine to the remote server and it may be that transfer mechanism that is only occurring every minute.
Unfortunately the crt extension does not give us too much extra debug info but it may help to get a clearer picture of what is going on if you post a debug log extract. To do this edit weewx.conf, set debug=1, save weewx.conf and then restart WeeWX. Let WeeWX run for at least 10 minutes and then take a log extract showing the entire WeeWX startup and the following 10 minutes of log activity. The log should be in /var/log/syslog unless you have changed it. Post the log extract without any changes. At the end of the day though you will have two choices in terms of realtime.txt update period, either on every loop packet (2.5 odd seconds) or every archive interval (currently 5 minutes).
