DateTime Adapter not starting

I have moved my IoT setup to a new location (with an TP-Link LTE modem as base station), did a new setup and since then have trouble loading/enabling the datetime adapter. When try to I start, this the readout of the Log is as follos below.

Thanks for help or ideas how to solve this!

The adapter is trying to install its dependencies from but is failing to connect to that site. Does your gateway have internet connectivity?

I thought, that this might be the problem. Nevertheless on my Laptop I have a quite stable (although sometimes slow) connection while trying to start the adapter on the iot-pi. Therefore I was wondering, if there might be other issues as well. I’ll see if I can boost my signal or use another wifi source and try again!

So, I solved the tunnel/https problem here: "Tunnel not set" or https problem (general problem with connectivity) and now the log shows that the DateTime Adapter installs correct and also seems to start/stop in a correct way.

Nevertheless, it doesn’t show up in the rules. Any Idea, where I could change something so that works.

You have to add the DateTime “device” before it will show up in the rules interface. Have you done that yet?

Sorry, didn’t find the time to reply. Indeed it started working after I let the DateTime interface finish it’s install and added the adapter. Thanks.
