I need a very simple relay to operate a wired electric door latch. The connection to the door is available at the Indigo server location. So, all I need is a very basic relay. This one was low priced and looked like it would do the job. https://www.amazon.com/dp/B01CN7E0RQ
I can probably create a simple virtual device with a couple of shell scripts. But, I was wondering if anyone here had any experience with this or some similar product.
TIA
