Cayenne support WiFiEsp https://github.com/bportaluri/WiFiEsp

Cayenne have any intention to support Arduino + ESP8266 with AT commands?

Welcome to Cayenne!

It’s not official, but here is some code that works for some people: WifiShield with arduino uno compiling error - #10 by adam

I’ve been having out-of-the-box good luck with the ESP8266 integration,
particularly ESP12-e (Generic) provided by Arduino IDE.

My only disappointment being GPIO 16 and GPIO 14 (both must be controlled by some virtual pin functions/code workaround) on the ESP12-e. That ESP8266 is awesome!

Thanks Adam!
I already try it and make a question to Kreggly in the link you send me.
