Like the title implies, I'm wanting to be able to control a simple SPST switch in a remote building in a different part of the state using a smartphone. I just need to open a NC 24VDC circuit.
The remote building has WiFi.
Anyone know of a reliable manufacturer or have practical experience with a specific product?
Oh yeah - I've googled and come up with quite a few different options, but hate to rely on the "5 star" ratings that products are sometimes given.
No telling whose brother-in-law, etc, gave the ratings to make them look good.
I'm hoping to find something that has an internal dry contact switch, with two external terminals to put in series to open my 24VDC circuit.
I swapped out 20 standard rocker SPST with these - https://www.amazon.com/Switches-Compatible-Neutral-Schedule-Required/dp/B083JW2FSP/ref=sr_1_23?crid=Q45JWEP54M4G&keywords=google+home+wifi+switch&qid=1642449667&sprefix=google+home+wifi+switch%2Caps%2C69&sr=8-23
But make sure your wiring supports a common Neutral Wire. Most of these WIFI switches only work with a CNW.
I replaced SPST with one with an antenna to a second switch that ran on a 9 volt battery. You just stick the box anywhere.
Put it on the outside of a barn door. No problems.
Old barns seem to have one switch all the way to the back.
Real simple
Instant 3 way switch.
Great leads - thanks all.
Throw in a Nest thermostat, Ring cameras, and a StreamLabs water usage/cutoff valve, you have the makings of a Smart House.
If you decide to throw a lot of WIFI devices into your house/business, make sure you upgrade your wireless router to WI-FI 6. Too many devices vying for bandwidth can cause all sorts of connection errors with older routers.
Otherwise if you're only using a few devices, you should be good to go.
Make sure that the switch contacts are rated for switching DC - DC is harder to switch (off) and may result in arcing of the contacts. Down here for example 240VAC switches can arc on 12VDC circuits.
