Hello,
It is possible to connect our devices to Siemens Logo Controller. You need to connect router LAN port to controller Ethernet port. Controller should detect router LAN network. How to configure controller further you should look up to Siemens forums.
If you are talking about Teltonika Bluetooth Pucks, then if controller has bluetooth functionality it may be possible, but it is recommended to connect pucks to router and send data from there.
Regards.
