Hello

I want to place the sensor, where I do not have a WiFi connection (street lamp pole). Which module with WiFi-Hotspot will be good for connect via 4G? How high will be the monthly traffic?

Thank you and best regards
Paddy

Welcome!
I have never had good experience with such hotspot. We can’t guaranty it will work directly. Maybe you could programm something with a NB-IOT module.
You can calculate the size of the payload:

    },

  },

}
