we have to create a MQTT server, an application that send "REQUEST TURN ON RELAY1", this request is sent to the MQTT server and the MQTT server send command to the relay board...
We don't know the MQTT protocol so you can use a router with OpenWrt.
The router with OpenWrt, for example:
https://www.amazon.it/GL-iNET-GL-AR300M16-Pre-installed-Performance-Programmable/dp/B0777L5YN6/ref=sr_1_5?ie=UTF8&qid=1547504568&sr=8-5&keywords=openwrt&th=1
On this router there is a OpenWrt operating system which is a Linux Operating System where you can load PHP or other Linux Packages. We can use the router to connected with the MQTT server or install the MQTT server ON THE ROUTER and our board is connected to the router...
The router has two ethernet interface.
One interface could be configured as DHCP and connected to internet. The other ethernet interface could be configured as [login to view URL] and connected to our board which has the [login to view URL] ip address.
