About This Project
A Smart_home system with ESP 12E sensor and activator nodes. Which i can monitör inside outside temps, unlock entrance door, open-close central heating and enable-disable corridor pir lights. If anybody intrested i can share the codes of arduino and ESP12e nodes

Triggers & Alerts
I was using 2 Pir sersors externally which triggers 12v to led strip on corridor, i connected one optocoupler to this 12v output and triggers to arduino input. If any motion detected, arduino input trigers and cayanne sends sms
Scheduling
none used
