2pcs DC 12V FRM01 Timer Delay Relay Module Multifunction Infinite Loop Timing Self Lock Relay Cycle Timer Module with Segment LEDs Display for Smart Home Automatic Control

Cool little board, does what it says. Videos online how to program it but it's a basic logic button board

Lots of programming options. I used it to automatically switch off an annoying option each time I start my car. (Auto stop-start) The feature still works fine, but this relay makes it off by default until I turn it on. It's been working great for more than a month.

Works just fine so far, but the documentation, which doesn't come with the order so you have to Google for it, is pretty badly translated. There are no graphs or visual representations to help overcome the terrible translation, so I had to kind of figure it out through bench testing. Did not come with a mounting plate or standoffs, which is not good. Luckily for me, it's mounted to a non-conductive surface, but something to keep in mind for anyone else. I wish there was a way to turn off the display when in operation to it's not shining like the beacons of gondor, but it's not a deal breaker. Once I figured out what the setting I needed was, it was easy to program and easy to set up. Really great value for the money, and it looks like it probably has the capability to do just about any timing function you could possibly wish for, if you can figure out the instructions.

Works as it should
