IOT with Cellular Modem to listen to SMSCB (Cell broadcasts, e.g. amber alert, not texting)

Thanks for reviewing my post.

I need to use an IoT device, i.e. SBC, to connect and interface with a Cellular Modem, like SIM7600G-H and listen to Cellular Broadcast messages, e.g. Wireless Emergency Alerts or like Amber Alerts. These messages use a control channel to send alerts out by message Id to all cell phones in a geographic area. Not all modems support SMSCB features. Anyone work with SMSCB or cellular modem with global band support (i.e. band 3 and other US bands)? I've had problems receiving alerts, of course they don't get emitted often. Any experience using this set of features would be appreciated. Thanks

Wifi switch to reboot my Cable modem?!

Hi,

Is anyone aware of a switch that will turn back on regardless of it's connected status?

I'd like to reboot my small IT closet in a remote facility. I've yet to find a switch that will turn back on if the WIFI drops.

Thank you!

Suggestion for non wifi based wireless switches

So I'm trying to remotely control the lights in my house but do not want to connect them to my home WiFi network. A 433Mhz RF receiver connected to a relay seems like a good option. I can control the receivers with a hub built using a raspberry pi perhaps. This way the only internet connected device is my pi. Is there a better solution than this?

Connecting a bunch of WiFi switches to my home network makes me nervous, especially when all the device needs to do is turn on and off. Also with this solution, I can always have a separate remote that can work with the lights even when my wifi network is down.
