I see that milliseconds are selectable for the hour meter, but the default execution schedule is 1 second(s). Does this mean I can set the group for executing timer 1 hour(s) and still get accurate hours every hour? I am sorry if it is a dumb question. I don't know how that counter works. I didn't see it in the video or on the page for the hour meter. If it is there, I didn't catch it. * * * Tried with timer set for 5 minute(s), and after 5 minutes the value did show 3 minutes of uptime when I tested 3 minutes of uptime. ---

I have retentive checked, but all my hour meters reset to 0 when I reset the Boolean to 0. I have a boolean for running. It sets the hour meter tags for the the machine. However, it was 7 earlier and now it is only 1, so it reset. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/2/b21c701783afd5e607d34c898308b0d33a67e9a4.png) I have a script that sets the booelean to 0 at the end of shifts. However, my meter is never supposed to reset. * * * Well the reset happened 30 minutes ago for running booleans. They toggle on and off all the time. I did just add a machine to the transaction group today though. So maybe when I added that, the meters reset? Do hour meters reset if the gateway goes down? Testing, setting one to 10. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/5/95b8d509ff76074d5c1a6f42140eac70dcf3630a.png) Moments later it broke. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/e/ee0ac5d82437419b9e4fccb8c63b5922cbf75af4.png) * * * Oh no, this hour meter is useless? [Retentive Hour Meter Resets on Group Disable](https://forum.inductiveautomation.com/t/retentive-hour-meter-resets-on-group-disable/7691)] I need an accurate hour meter from the gateway, not the plc. I am going to use event scripting till I learn a better way. ---

Thanks, that answers my questions about the transaction group hour meter. I am going to see if anyone knows a good non-resetting reliable hour meter. [Hour meter recommendation](https://forum.inductiveautomation.com/t/hour-meter-recommendation/77143)] ---

I normally just write PLC code to do this, and record it often enough to catch impossible discontinuities (like losing the value due to a program download). ---

I don't know how to mitigate the loss of the hour data on a download. So I thought that a separate device would be best. I like the mechanical rollover because then if it fails, I still have the last value. Seems like there is a hole in the market though as I don't see a device that combines the mechanical rollover with having an output to read the value to the plc. I thought it would be good to make that separate thread to ask about such a device that others might have found.
