Has anyone seen an ESP based module that replaces a standard mains wall switch? I’m looking for something miniaturized, not a huge brick like the Sonoff, something that fits inside the wall switch box.
Leviton makes computerized wall switches with all sorts of features, that fit into a standard switch box… but they’ve obviously spent a lot on R&D. How hard would it be to achieve the same with an ESP?
I’m curious to see how Leviton is getting the low voltage to power their electronics - that seems to be the biggest component of a diy module. Not curious enough to spend $50 on a switch I’m going to bust open.
Need to steal power as a switch is in series… these fancy switches might not work with LED lights as there might now be the ability to have some current flow… as a filament bulb can have a fair amount before you see it on… if you try with some LED bulbs they will glow fairly bright and annoy people that think they turned them off
That could be a problem if only the hot line is available in the box., The few I want to retrofit have both hot and neutral (and ground) present, but only hot is switched.
Yep, they place the switch inline and “steal” power… http://www.laureanno.com/x10-6.html switches steal power, lamp modules get their power much easier…
Yeah basically would be awesome to find esp-main switch, esp equivalent of those rf socket switches and esp led bulbs.
Would love to design one but the CSA/UL approvals and tooling for a complex case would be very expensive!
Well sure, any type of regulatory approval, and associated insurance would cost a fortune, though a hobbiest prototype doesn’t need such oversight.
I’m sticking with battery powered for now, however I wish the esp booted faster, it takes several seconds from reset until the network is available. It makes sleeping undesirable for a responsive switch.
Yep, 433 to wifi is what I am working on just now
