4 state switch

Setup, Configuration and Use Beginners
1

I have fan where speed set as follows

  1. relay ON - speed 1
  2. relay ON - speed 2
  3. and 2. relays ON - speed 3
    I have MQTT bindings item.
Switch	rychlost1	"rekuperacia rychlost 1"	<switch>	{ mqtt=">[localbroker:/mama/rychlost1/Switch:command:ON:1]", mqtt=">[localbroker:/mama/rychlost1/Switch:command:OFF:0]" }
Switch	rychlost2	"rekuperacia rychlost 2"	<switch>	{ mqtt=">[localbroker:/mama/rychlost2/Switch:command:ON:1]", mqtt=">[localbroker:/mama/rychlost2/Switch:command:OFF:0]" }

How have I to make switch with 4 buttons (button1=0, button2=1, button3=2 and button4=3)

Use a single item of type Number. In sitemap, you can use Switch and mappings=... so it gets displayed as bunch of buttons (as many as you need states).

Thank you for your time. Solved.
My procedure and Guide for any users with MQTT binding:
You need Items with bindings:

Switch	relay1	"relay 1" <switch> { mqtt=">[localbroker:/esp8266/relay1/Switch:command:ON:1],>[localbroker:/esp8266/relay1/Switch:command:OFF:0]"}
Switch	relay2	"relay 2" <switch> { mqtt=">[localbroker:/esp8266/relay2/Switch:command:ON:1],>[localbroker:/esp8266/relay2/Switch:command:OFF:0]"}
Switch	relay2	"relay 3" <switch> { mqtt=">[localbroker:/esp8266/relay3/Switch:command:ON:1],>[localbroker:/esp8266/relay3/Switch:command:OFF:0]"}

One “virtual Item”

String	relay "relay switch [%s]" <switch>

Sitemap

Switch item=relay label="Relay switcher" icon="switch" mappings=[off="OFF", relay1="Relay1", relay2="Relay2", relay3="Relay3"]

and Rule

rule relayCommand
when
  Item relay received command
then
  if (relay.state == "off")  {        // all relays OFF
    sendCommand(relay1, OFF) 
    sendCommand(relay2, OFF)
    sendCommand(relay3, OFF)
    }
  else if(relay.state == "relay1")  { // activate relay 1
    sendCommand(relay1, ON)
    sendCommand(relay2, OFF)
    sendCommand(relay3, OFF) 
    }
  else if (relay.state == "relay2")  {// activate relay 2
    sendCommand(relay1, OFF)
    sendCommand(relay2, ON)
    sendCommand(relay3, OFF) 
    }
   else if (relay.state == "relay3")  {  // activate relay 3
    sendCommand(relay1, OFF)
    sendCommand(relay2, OFF)
    sendCommand(relay3, ON)
    }
   
end
