Wired Home Automation solution?

[KAKAN]

I'm in the market for building wired home automation, but I'm unable to find any standards that are used in India. Even most electricians just recommend going wireless.
KNX, which is a popular standard in European countries, is almost non-existent here, and imported switches are expensive.
OneWire protocol might be possible, but then again, not sure how many actually support that either.

There are some projects online like:

GetWired

A complete solution for easy-to-use and affordable wired home automation

www.crowdsupply.com

And even some upcoming ones like:

Open Smart Kit

Open source, flexible, modular hardware modules with Home Assistant compatibility for any of your automation needs

www.crowdsupply.com

Right now, GetWired looks to be the most promising option. Aside from that, I suppose the best way would be to just have Ethernet wires to all rooms in a house and hope there's some standard in the future like GetWired which can act as a hub per room and communicate to a local HA instance using Ethernet.

Of course, a smart home should be "smart", so in case of failures, manual overrides are a must, whether that be using a 2 state relay, or some other method

Spoiler

There are many reasons one would want to build wired home automation, so please don't say in the thread to go for wireless.

Hello

I was in same dilemma when i wanted to automate my lighting and fans showroom: 250+ light points, 30+ fan points, aircon, security, and alot more.

Ps: My knowledge of open-source automation, proxmox, and many apps which people use, is very very LOW plus since it's a showroom, i wanted it to programmable easily without me ever going there for any hiccups.

So I took quotations from brands which we are dealing with :
1. Goldmedal
2. Havells Crabtree
3. Osum
4. Schneider

We also compared many many options which we sell in wireless. But you are right,
Wired automation has no comparison with wireless automation.
Wired is overall better. Period.

We settled for a brand and specific modules which suited our requirement. One-size cannot fit all here.

Now il list the type of solutions different brands offer:
Knx
Bus Bro
SL Bus

Each solution has pros n cons.
It's a very very indepth topic and selection depends on in things like
1. Tech know howto do automations on your own
2. Architect has given electrical looping layout?
3. Lighting plans and lighting budget
4. Area
5. Devices
6. Budget
7. Pre-sales services
8. Post sale services in your region
9. Over the cloud tech support
10. Space for distribution box
11. Spaces for switches
12. Spaces for controllers/keypads/buttons

If you can put things here, i can answer, as it will help me also learn new things from automation experienced members here on TE.

There's also Modbus and many other protocols, but the biggest challenge is that aside from KNX and 1Wire, most are built either for building automations, or for industrial automations. The first means you can only buy things in huge bulk, and the second means both bulk and usually large/ugly switches/DIN rail solutions.

Best ones are typically some sort of hybrid like KNX/Modbus where the actual standard between switches/fans/etc to controllers is their own protocol, and from controllers to the main hub via Ethernet/wireless/any other standard easier for computers to work with.

1. I consider myself pretty technical, and I can configure/flash stuff as I want to as well, so technical challenge, at least the software side, shouldn't be much of an issue. Still, I'd like to go with some trusted solution since I want the home automation to be "set up and forget it" for a long time.
2. Yep
3. Preferably lights controlled via relays and ones that can be programmed for fun via code/PLC
4. Not very big, each floor should require 2 WiFi AP at minimum to have the whole house covered. Typical 2 storeyed house.
5. Not sure what you mean...
I will have more than 80 switches overall, 12ish fans, preferably a thermostat as well, for ACing the whole house
6. Budget shouldn't be a concern for now, but a limit of 10 lakhs should be good enough, I think?
7, 8. No idea, nobody I asked did wired home automation at all. Most are either going with Shelly, Phillips, or some local brands which sucks.
9. If avoidable, please no cloud. If not avoidable, there should at least be a way for the device to work without cloud. I'll just keep it permanently disconnected. I do need support for Home Assistant though.
10, 11, 12. Each room has enough space, I think. This can be changed, so shouldn't be an issue.

I'm just exploring for now. My plan is to just have CAT6 or Fiber cables running to every part of the house, and figure out the rest later.
