How can I control air conditioner using ESP 8266 and alexa
Pranay Stark

The relay is rated for 40A so it should be able to handle an air conditioner, but it’s best to check with the specs.

If you want temperature control however, I don’t think this method would work for you; consider adding a temperature sensor and look into developing an Alexa Skill, so you can define custom voice commands.

Hope this helps!
