Dear IoT Creators,

we are using the following sensor which is also listed in the off-the-shelve listed hardware devices in the docs: https://docs.iotcreators.com/docs/ellenex-pls2-n-liquid-level-transmitter

Until now we used the device with a 1NCE LTE-M Germany modem configuration and want to switch now to Deutsche Telekom M2M SIMs. We have the needed configuration from Ellenex for Deutsche Telekom for their on-board modem:

cgdcont="IP","iot.telekom.net" 
nwscanmode=3,1 
iotopmode=0,1 
band=0,80080,0 
cops=1,2,"26201" 
scramble=0 
qicsgp=1,1,"iot.telekom.net","","",0 
cfgstr1:at+qcfg="roamservice",1,1

We updated the config of the device accordingly. But we run into connection issues:

Do we first need to register the device / EUID & SIM here at iotcreators to get a connection established?
We would prefer to use direct IP connection by just placing in a DT M2m SIM in the device as we are used with 1NCE.
We have a couple of devices and matching a SIM with a device is creating extra friction in our process.

Thanks for you help and best wishes,
Lars
