Turn off VPN and Private Relay
Works great! As other reviews noted; turn off VPN and Private Relay if the app is not communicating with your Sigma. If it can log into the Sigma's Wi-Fi but not get the green light on the app, that is most likely your problem.
Turn off your vpn
It works well. Unfortunately it took me a while to realize I had to turn off my vpn for it to work.
Too many times to get app to work
For some reason it is hit and miss with the app, my phone and the device, waste 1 hour to get them to connect. Why can’t they just make their device work with its own screen.
Database needs to have more entries
Got it today and app is very basic. It would help to have more coins in the database. It would also help to let user enter their own entries with human friendly names for coins and bars. Sigma mini has lots of potential and please don’t limit it due to app limitations
Does not work
Does not reliably connect to your phone/tablet. Frustrating experience.
