I'm using the industrial I/O board along with a node red interface in a remote application where there is no internet access (maple syrup collection and processing). In my node-red application I use influx db and graphana locally to track and trend temperatures and flows. I just realized this morning that the time on my PI4 was off and screwing up my data collection. I know that the Industrial I/O board has a real time clock and battery. Can this be used to keep time on my PI for data collection when I'm not connected to the internet? I'm not finding much for information on how to use it.
Using the Real Time Clock on the Industrial I/O board

Thanks for the info Alex. I'm back looking at this. My application (running node red on a PI4) will be running with no outside internet connections. I think I can figure out how to update the PI time with the node red dashboard (haven't tried it yet) but how then do I utilize the real time clock and battery on the board to hold that time after manually setting?
If you put the script in cron or run it at few minutes interval from exec node, it will maintain the system time.
The card is connected ? What is the stack level settings? It respond to the megaind command ?
