I am developing a simple angular app with IoT which is detecting the temperature of a sensor.
All I want to do is, when the temperature is above 50, I display a message in my tv. What would be the best way to do this? My tv screen is connected to Chromecast, I have raspberry pi (If needed) and I can if needed connect a computer to the tv screen.
PS : The angular app is on my phone, and I want to display the message on the tv screen.
Any help would be appreciated
