I have a running server (windows) with Node-red which send me various notification to connected devices via WhatsApp and emails thru Internet. I need to receive those notification in case of internet is down, while connected devices (Andorid, Iphone and so) are in the same network as the server (same LAN). Controlling node-red is working in this scenario because I'm connecting directly to Node-red Lan IP address, but notifications from Node-red are not working.
I need to receive those notification even when I'm sleeping and the phone screen is off (internet down).
Is it possible? Any advice?
