    I am looking for a wifi device that would work on Tuya or Evellink and preferably be powered by 12V DC. It would have at least one input and at least one relay or OC type output.
    When an input is activated, it would send information to the application.

    Look for the garage door module. You will set up notifications by programming events.

    I haven't tested it but there are screen shots on the relevant vendor's website:

    Control your Arduino projects from anywhere in the world with a free app thanks to the Tuya IoT interface!

    Plug the Tuya IoT interface module into your Arduino by using the included 4 male wires. Then connect your Arduino with the IoT Tuya cloud by simply installing the Tuyav library, which is compatible with ATmega chipsets (or AVR platforming). This will enable you to connect with the Tuya app over WiFi and lets you control up to 5 outputs.

    How much of a hurry are you in with this module @xury ? If you are not in a hurry, I might order the first one and test it.

    Added after 3 [minutes]: .

    The above device is an overlay on the Arduino and communicates with it over the UART, the software on the Arduino side is available on Github. Basically it chats with the Arduino via the TuyaMCU.... which you already know.

    I am in no hurry. A colleague wants something to hook up to his alarm and turn on nothing with it and get notifications. He doesn't have a public IP and doesn't want ZeroTier. So something has to be on the cloud.

    How about something DIY with Supla? With Gui Generic?
    Pairing and configuring Supla devices without using a mobile phone .

    Well, what kind of alarm is it?
    Personally, I try to avoid solutions based on connecting to the router when the router doesn't have any backup power - then the GSM module powered from the control panel which at least makes it possible to operate it in a situation where there is no power in the network.

    The alarm is an old Rp140 . Of course I know about the weaknesses of this solution. I had completely forgotten about Supli. So if I upload Supli to my own DIY I can get hooked up to the cloud? For free?
    Personally I only use MEW-01 and that locally over mqtt.
    Esp I have a lot so I protest.

Topic summary

The discussion focuses on finding a 12V DC powered WiFi relay device compatible with Tuya or Ewelink apps, featuring at least one input and one relay or open-collector output, capable of sending input activation notifications to the cloud. Recommendations include a garage door module with programmable event notifications and a Tuya IoT interface for Arduino with pre-installed firmware enabling cloud connectivity. The Arduino-based solution communicates via UART using TuyaMCU protocol, with software available on GitHub. Alternatives such as DIY implementations using Supla firmware with GUI Generic were suggested, offering free cloud integration without relying on public IP or ZeroTier VPN. The alarm system in question is an older Rp140 model, and considerations about router power backup and GSM modules for reliability were discussed. Local MQTT control using MEW-01 and ESP devices was also mentioned.
