    Hi all,
    I'm looking for a GSM gadget that would send a text message or a call to another phone when an input is triggered by an external signal.
    So far I have found a tiny GSM gadget that should send a call and text message to a specific phone number when its PIR sensor reveals a moving body within the range, but I don't think I'll be able to modify it to work with an external input, nor is it easy to configure, and the Chinese instructions do not help.

    Thanks!

    is it a Sonoff?

    also an RTU 5035 might work?

    So very sorry for my late and slow reply, but I wasn't notified of your answer back in March and only found it out because I was browsing my followed threads.
    So sorry, again!

    Well, no, as far as I have understood, the items you wrote about are systems that send a signal or close a contact when they receive a call from an authorized caller.
    My need was the opposite, to receive a text message or a phone call from a gadget when an input of its is triggered by an external signal/switch.
    I would like to be called/texted when a certain condition occurs and I'm not attending the site.

    Thanks for your reply and, again, I do apologise.
