SMART Stuff that does NOT Require Web Connection.

[Lost_in_the_HTTP]

Whatchagot?

I have a few SMART switches that only work if the web is up, which isn't all the time.

Looking for stuff that works in house/local and doesn't need a distant server. I think TrendNet has something, but who else, if any? Out of box only. Too stupid to cobble something up with code.

I'd like it to be able to use the web if I ever want to do something remote via phone, but that would be rare.

Home Assistant only needs internet connectivity when you are setting it up for the first time. then you can keep it off the internet. should talk to all the smart stuff you bought. downside is of course it need to run all the time. I have it running in a VM in my environment.

What is it you're trying to achieve? Are you looking for voice activation, motion sensing, or simply having existing outlets switched?

Mostly timed on/off and self-adjusting for seasons.

Rare activation by mobile device.

I don't want software that needs to run. I want devices to work through a LAN.

Err, that is what all appliances are, they run a firmware version of some controller software. And I am not aware of any HA appliance that does not require constant internet access. Home Assistant was built with privacy in mind.

Get a rpi 5 and a ssd and run HA on it. HA writes a lot of events so SD cards are not a good idea.

With HA you can schedule events like turn on or off. you can use the browser interface or install the app and control from your phone through wifi as well. So you got your scheduled events, but you also have software buttons that can control the switches.

you can use HA to control your IP cameras as well.

I use it for my hydroponic pet project.

Arduino/Raspberry PI and relays. If you want something a little more pre made, there's these boards:

4-Channel USB Relay Board with 6-Channel A/D Interface

Uses simple serial commands that are documented so it's easy to write a python script or C++ program to control it. That's actually what runs my hvac, I didn't know Arduino was even a thing at the time I implemented it. I also have an Arduino now for some monitoring duties such as AC power loss and mouse traps. Been meaning to design a system that's a bit more modular though as my current one is all hard wired. I'll probably make the new version use POE ethernet as that will handle power and isolation, and make use of existing cabling infrastructure and all associated commonly obtainable parts like patch panels etc.

PLCs are an option too, but never looked much into them and they are probably really expensive. You also need proprietary software to program them. But once they are setup they don't need any sort of web connection or phone apps or anything like that.

Yeah op wanted finished product. You should look at ESP32, much more capable than Arduino.

I just buy remote switches and put them wherever they need to be. I like simple things.
