Forgive me if this is the wrong forum, if it is let me know and I will correct that.
Here is the situation. I work for a company with a large production facility. Currently we have about 45+ TVs that have a PC connected to them to display information produced by our communications department. The problem is when there is an interruption in the content either due to the PC's getting updates and rebooting or some other loss of signal issue, the TVs turn off. This then requires our local IT team to travel the production floor(over 1.5 Mil. Sq. Ft.) and manually turn the TVs back on.
So the question is: Is there a way for a Raspberry Pi to be used with an IR transmitter to turn a TV on? If so, if we outfit all the TVs with these, how can I send the "Turn On" to all of the PI devices at once to do just that?
