I'm building a home automation system using Arduino and would appreciate recommendations for a reliable wireless communication protocol. Please share your experiences and insights on protocols that have worked well for home automation projects.
Please specify the functions and devices needed. No protocol is perfect for all kinds of communication.
2.4ghz wifi is the standard for home automation devices. But most of the smart devices have automation software included so there's really nothing to invent.
Alexa uses Matter
One of the considerations should be the maximum distance. WiFi e.g. will not go further than around 30 meters (without repeaters).
I am trying to decide between Z-Wave and Zigbee for my home automation project. Can you help me compare the two protocols and recommend which one is the better fit for my needs?
This could be achieved through new antenna designs, signal processing techniques, or even new Wi-Fi standards.
I agree with it.
What have you found so far?

A key consideration would be what protocol(s) are used by the devices you want to interact with ...
As already noted, Matter is currently "hot" ...
Google Z-Wave vs Zigbee
You'll find hundreds of opinions, with no definite conclusion as to which is better

Aye.
@catox69052 In Engineering, there is no such thing as "best" - it's all about tradeoffs.
Z-Wave, Zigbee, and all the rest will all have both pros & cons - so it's up to you to weigh how those line-up with (or against) you particular requirements & constraints.
This is why you need to have a good definition of your requirements & constraints before you start...
Zigbee uses 2.4GHz world wide so you can buy devices from anywhere and use them anywhere.
Z-wave uses country specific frequencies so you'll probably be locked into buying from suppliers in your home country, so the range of devices is smaller and prices are higher.
Quality wise they are equally buggy.
The Zigbee2MQTT bridge makes it easy to integrate WiFi/Ethernet Arduinos with Zigbee devices. I have no idea if there is a Z-wave equivalent.
WiFi is power hungry and therefore not suited to battery powered devices.

I'm sure there are - all the protocols can be "bridged" to the internet
true...Zigbee uses a lower frequency band than Z-Wave.
No - the other way around!
Z-Wave is sub-GHz:
