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

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
