Hi there, i don't know if writing an issue is the right way, but I just try to get help on this way. After the start command I received the following error messages:

root@maserver:/maserver# node mobilealerts.js

Local IP address for proxy: undefined

Hi, I get the same error. Can someone provide the format for the lastSensorMessages.json file?

sarnau commented 3 years ago

An empty JSON file should do.

That's fixed the problem. Thanks.
