Thanks for sharing your ideas TotallyInformation,
I'm guessing DI here means "Digital Input" where Node Red will wait for this DI status to change from "false" to "true" before triggering a series of events or actions in Node Red.
I digress, I am also trying to figure out a way of generating an automated alert message using Node Red and WhatsApp. I have successfully done it with Telegram, and it works pretty well I must say. But, unfortunately in some work environment, Telegram ports are being blocked from entering a company network.
At the moment, I have sent a request to WhatsApp Tech support to see if their API could be made available for non business WhatsApp accounts.
