Fuel tank fill sensor Agent #568

Open BrianJKoopman opened 11 months ago

BrianJKoopman commented 11 months ago

There is some serial device that reads the fuel level of the main fuel tanks at site. This needs an Agent written for it. The start of some driver code has been written, get in touch for details if you're interested in working on this agent.

If possible, more information about the device should be posted here.

The monitoring is between Raspberry Pi B2 (pi-wheather-site) and USB to serial port (ttyUSB1). This are monitoring the large tanks that feed the generators; the comunications is bidirectional, where the script (path /home/user/Scripts/fueltanks_monitor.py), ask to serial port connected to tanks monitor device, that include a touchscreen, but this can´t trasfer directly the information of the level sensors to the computer server of monitoring data as Grafana or OCS; for this reason the reply of the tank monitor is in the ttyUSB1 in the pi-weather-site and this data should be included in monitoring data and is necesary create a OCS Agent for the large fuel tanks and obtaing this readings.

Thanks for posting this info. I was more wondering about the device at /dev/ttyUSB1 -- the tank monitor device -- any info about that?

Only we have the information shared by Delwin Johnson, where he say us that the model installed haven't the propiety to share data between ethernet output; I attach now whit this comment the information available. GLT622 Protocol.pdf GLT622 user manual console.pdf
