CumulusMX.Servce Issue

[DeerWeather]

Hello all, I am running MX on a Raspberry PI Zero W attached to a Davis Vue Console / datalogger. Been working for years on a PI-3, I am just trying to move my system to the smaller platform.

When I start MX things with : sudo mono /opt/CumulusMX/CumulusMX.exe Everything works fine.

However, I am having issue running MX as a service.

I run this command to configure the service: sudo nano /etc/systemd/system/cumulusmx.service

[Unit]
Description=CumulusMX weather station software
After=network.target

[Service]
WorkingDirectory=/opt/CumulusMX/
ExecStart=/usr/bin/mono CumulusMX.exe
Restart=on-failure
User=frank

[Install]
WantedBy=multi-user.target


Here is the service status immediately after starting the service:

Then when I check the status again, I see this:

Tinkering around with it yesterday I somehow managed to get the service up and running and it ran for 24 hours perfectly until I needed to re-boot the zero.
I am close for sure but need some help with some tweaks my cumululsMX.service config.

There is a sample service file in the zip.

When running as a service under Linux, MX must be started with the -service parameter

That worked and everything seems to be fine now!! THANK YOU and have a great day!
