You used the parameter --remote on the homey app install command which isn’t a valid parameter. --remote is to be used only for homey app run.
So, it’s like this:
homey app install Installs the app on your Homey, no debugging output
homey app run runs the app from a docker* container with debugging output
homey app run --remote runs the app from your homey with debugging output
When you use homey app run --remote the app will keep running on your Homer after quitting your terminal app.
* needs docker setup, not recommended for novice users
