I have written an application for a silent and sounding ALARM system. The silent alarm sends an SMS text message and/or an email. The sounding alarm, sends out the SMS and/or email and turns on a siren.
I would like to flash a virtual LED to give warning that the SIREN is enabled and will sound if conditions change (e.g. unintentionally turning off the ALARM bypass).
1 or 2 Blinking LED’s in the BLYNK app, would eliminate attempting to blink an LED from the hardware app, and which could/would saturate the server with ON/OFF’s.
