How to rf 433mhz on pls advice us

[@david_p.]

Sorry, I don't quite understand the comment. It does not work by rf, it is a relay that is activated via wifi, or physically with the button. The function is to make a bridge between 2 contacts, without power so as not to overload the contacts.

I meant I wanna add rf 433mhz also

[@david_p.]

With this module you cannot add rf 433mhz, it only works with wifi. You could add an rf 433 module and have it work when powering this Sonoff, but I don't know about that module.

waste of time don't even watch it

[@grahamefeltis6559]

Why?

[@david_p.]

If you do not know what it is used for, it is normal that you do not understand it and it makes you feel like a waste of time. With this you can automate everything you can imagine, turn on any device from anywhere in the world, open a garage door from your mobile phone, schedule the ignition of an automatic irrigation system, etc. With the advantage that you can feed it from 5v to 24v without the need for a transformer.
