It sounds as if the cloud functionality has not yet been activated.

The supplier has stated that the batteries and power supply unit are not included in the scope of delivery.

Hello dear Community, I have now found the answer on the website. https://www.shelly.com/de/use-shelly-for/smart-assistants/samsung-smartthings-1. So it should be possible to integrate the link.

The device is integrated into Google Home via your Shelly account. The device is of course compatible with many other systems. Ultimately, it simply runs via WLAN and can be addressed via the IP.

No, each device is independently connected via WLAN to the Shelly Cloud. And via the Shelly Cloud, it can be partially integrated into other systems.

Schelly guarantees that it runs between 0 and +40 degrees and complies with all data sheet values. (Measuring accuracy, battery life, ...). Experience shows that it will also run reasonably well between -20 and +60 degrees. Please make sure to place it outside, protected from rain and direct sunlight.

Any plug-in power supply, e.g. from a mobile phone, will fit. Only pay attention to USB-c

Yes, the voltage is correct.
