Is there any magnetic parking sensor with battery and TTN 868Mhz for europe available?
There is one available from Turbo which is 868Mhz - user manual
Besides this, there is also one from Libelium but haven’t heard from anyone successfully connecting to TTN yet.
TBS-220 is compatible to TTN? How can the addresses/keys be configured?
I am not sure if it is compatible with TTN. Best would be to reach out to Turbo directly so they can assist you with this.
Regarding to other topic here and guide it doesn’t look so…
We use these parking sensors (Turbo TBS-220) on TTN with the AS923 band plan. Yes, they are compatible.
There is one here also http://www.iemgroup.com/solutions-products/sensors/presto-sense/
