I have a Nextion display I have used on an arduino. I’d like to Use it ability to send switch input high low, and use the ATO control in Reefpi to read the on/off signal. Basically I’d like to setup multiple on off switch to turn on or off equipment ie pumps, to set up basic switch run a macro. Like a feed button on the control screen that shut off the pumps. Just some basic control light on/off pump control on off or even high or low speed. It would be nice to have a cheap touch on off control mounted in the stand. So I’d have some kind of quick access to control devices while Working on the tank instead of fumbling around trying to find my phone. To access Reefpi over the internet , I’m not looking for fancy touch screen, looking for cheap and quick acess of equipment and something disposable basically It going to need to be replaced ever 6 months or so ,be that’s is in the salt air in the cabinet. Simple hookup 2 serial wires 5v and ground. I got the hookup and the setup within Reefpi UI interface , but the code, no clue.any help would be nice. Thank you.
