That’s an interesting device. I never knew such a thing existed. Now I’m going to find a use for one!
It looks like there is a web-based user interface. Presumably you could use a scrape sensor, unless there’s an API which returns JSON or some other format.
Working out how it works and what URL to send to drive it would require more information either from the seller on ali or from @jordanfavre
Good luck on getting more help from the chinglish nightmare of the vendor’s ali page. Hopefully @jordanfavre can give more info on how he made it work in Jeedom.
Thanks for your reply ! Yes it’s very difficult to have documentation … Yes there is a web interface to manage relay but no documentation. On jeedom there is a plugin for this type of material. Maybe with a wireshark, I can test that
