B4J Question How to drive relay board by B4J code?

[amorosik]

Most of these devices are compatible with Alexa, Google Home, Ifttt, and others
The question is: how to drive them, in the sense of activating or deactivating the relays, and reading the status of the buttons, from the B4J code?

I don´t know how to connect to these but consider something like this. You can use a REST Api to control them. okhttputils2 is all you need.
