Hi, can anyone help me where to find a gateway, that can

- connect to one or more device(s) measuring temperature? -> device is sending these measurements via bluetooth 5.0

- and how to pair device with gateway?

- app as a middleware?

- gateway sending data to cloud using fx NB-IoT 

- and be battery drivin?

An ESP32 can connect to up to 7 Bluetooth devices at the same time. (Actually, all BT receivers/transmitters can do up to 7) IDF should be v3.0 or higher but it looks like support for BT 5.0 was added in 4.3 release. It can run off of battery and they can come with a battery holder pre-installed. Plus, it has WIFI.
