I/O expander is very awesome and with a remote control even for easy IR control.
The usefulness of such a device can only be realized when someone knows this could be someone turning on or off many specific relays or even doing bit based dimming using the outputs at a high or low state flags like a dip switch to represent different dimming percentages or maybe if you wanted one could just type in the number of percentage they would like their light dimmed on the remote and it would set the expanded GPIO's to represent that amount and have a separate controller automatically do the ZCD for the percentage of dimming...
I am amazed there are so many uses for something like this.
EVERYONE should keep this in mind:
What we have here is two powerful tools to accomplish things never before possible with such small amounts of money.
If you can eliminate a task that takes 5 minutes out of your day every day something as simple as turning on or turning off lights all together it would be the same as buying 100 days of your life back over the course of your lifetime. On average a 5 minute repeating daily task cost you 100 days of your life over your lifetime !!!
Is automation really about being lazy ? Or is automation really about reclaiming more of your life to use as you would like it? You be the judge but their are people who would pay millions if not billions to live another 100 days.
Really even if you are a staunch advocate against automation for whatever reason these abilities provide you with tools from which puts you in control so you can freely control something when you see fit with a remote controller. Building your own device does add another level of security and privacy if done correctly as well.
This stuff is just way too cool I need to get my hands on GPIO Expansion and Some IR stuff so I can partake of these insanely useful tools. The possible uses are endless in my mind.
