I was wondering if you ever thought about adding on a INPUT for an alarm. Something like a magnetic switch or a push button. SO you would have 2 relays to power and shut down devices and 1 - 4 alarms to control sensors that would send your SMS when they are either High or Low

Hello. Thank you for this. Is it possible to change so the relay trigs on a text instead of number ? i have tried change the ASCII code, but i dont know how to write a hole word. Looking forward to hear from you
