El CH4 PRO es el más adecuado para esta operación.
I remend this device:https://www.itead.cc/smart-home/sonoff-4ch-pro.html
It have second operation function.
I've been thinking about this, but what do I do with 1s timing?
You can use the 4ch pro module, that will do the trick

Hello
My name is Daniel Neacsu I live in Germany and I have a question:
I have a shutter lift system for windows, and I'd like to control it wireless.
The problem is that I need two wifi relays, but to act for only 1-2 seconds, if it acts more, the lifting system enters the programming mode.
These relays would like to be able to control them from the internet (or if possible with Amazon Dot -Alexa)
Please tell me if you have a solution for me ?
Thank you very much !
respectfully,
Daniel Neacsu
