Hello friends
How do I use a received fixed message that is always one to turn a switch on and off? That is, when the number is received, if the switch is off,turn it on, and if it is on turn it to off, please advise me.
You'll probably get more help if You're more specific.
Context is king 
What do you use to get status of light - MQTT? Rest? Other?
how do you turn the light on/off?
Is it a physical button or dashboard button you refer to?
If it's a physical button, how do you read it's state/how does it's push state reach node red?
What have you tried so far? (Post your flow & screenshots of it would help)

i have a touch sensor tp223 connected to wemos d1 mini and it work with mqtt
when i touch the sensor it will be send number 1 as payload to node-red
So I want to change the status of the switch when the message is received, turn it on if the switch is off, and turn off if the switch is on
Hi, when you reply to a topic, its wise to reply to the person otherwise they dont get a notification.
Ok, so you replied privately to me and i asked you...
When you reply on the thread, Please also, include information on...
- Does node-red get the lamps status? And what is its value for on and it's value for off?
- what protocol is used to turn on lamp?
- What value (number 0/1? Boolean true/false? String 'on'/'off'?) Is used to turn the lamp off and on.
and you replied...
