Roller blinds + ESP8266 + Cayenne

Hi,

How can i control roller blinds using ESP8266 and Cayenne ?
For example i want to open blind 10% or something else.

you can use this code https://github.com/myDevicesIoT/Cayenne-MQTT-Arduino/blob/master/examples/Actuators/GenericPWMOutput/GenericPWMOutput.ino

Sir,

Thanks for the code. Now days i was very busy, i will try do to something tomorrow.

I want to ask you something, how the ESP8266 will know the limits of the roller blinds?
How it will know when the roller is all open or all closed ?

I think i need to use limit switches. Is these any other possibility ?

yup, you are right you need to use a limit switch to turn off the roller blind when it reaches the end.
