Hi,

I am looking for such a remote control solution to initiate a phone call. The concept is similar to some existing alarm system: a user press a button at the controller, and an emergency call is initilized to call out to a pre-set phone number.

What I am thing is an device +app solution. Assuming the phone and the remote controller is within the same house
1. When a user press the button at this controller, it triggers an app in the phone
2. The app itself can initiate a phone call to a specific contact person. The user does not have to talk in the phone via the controller. Instead, the call itself can be treated as an alaram notification.

Would anyone suggest any products in the market that can do this job using a smartphone? Or if I have to build such a system, what key information I need to look for?

Thank you!

Hi,

You need to handle the button part and the application part separately. Assuming you need help with the button part, you can try this tutorial https://www.instructables.com/id/Tiny-ESP8266-Dash-Button-Re-Configurable/
The end result is a GET request somewhere you decide. If you have wifi but no internet than make the call to your phone's IP address (keep in mind that the phone's ip changes as you connect and reconnect to wifi). Alternatively a better solution is to use cloud such as AWS Lambda or AWS IOT which will be there always listening to your button press and whenever you make the call it will do something you want.
