and purchased the below item.

That should work.
Make sure you flash the ESP with the correct firmware to be able to connect it to openHAB: either with Tasmota or with ESPEasy. Connection to openHAB is done through MQTT.

It’s only a relay. If it can be commanded via HTTP as delivered, that will do.

Yepp, did not think about that one

Now I am a bit confuse, do I need to use MQTT & ESPEasy, or it can work without them. I will google for examples or guide, hopefully it should be available.

Thank you all.

It can work with just the HTTP binding:

HTTP - Bindings

I will google for examples

Something like this should work:

Switch YourItem { http=">[ON:POST:http://<ip address>/control?cmd=GPIO,<pin>,1] >[OFF:POST:http://<ip address>/control?cmd=GPIO,<pin>,0]" }

You may need to switch the “0” and “1” depending on how you connect the relay.
Of course you need to add the ip adress of your device and the GPIO the relay is connected to.
