That is disturbing and annoying. What type of supply are you using for the DC side of things for your Pi? The relay module appears generic and opto-isolated, would not imagine the problem stemming from there. Those sonof modules look interesting. I have toyed with the idea of using the older RF cont...

Sorry I do not have any advice to offer. But am curious as to what members consider the most anonymous and secure way to present the outward facing element of a home automation based system? Edit. Reason I ask is random bored law enforcement doing stuff like this : https://youtu.be/01dLzan9g0E?t=235...

I thought I would help you guys out. Don't waste your time programming the arduino. Check out Mycodo here: https://github.com/kizniche/Mycodo Very nice software. Runs on a raspberry pi. You can get the zero or the 3B+. I have mine running on a 3B+. Controls lights, fans, extraction fan, and dims. A...

With their market experience supplying HID ballasts, you would hope so.
