I want to set up some sensors in different places, which are wire connected to my Raspberry PI.
I want to send the collected data's wireless but without using Wifi protocol, The best option for low range IoT projects is Z-wave protocol. my next target would be using Kaa-IoT Platform as a Cloud Service, which makes my data available regardless of where I am.
I want to implement a circuit like this.
The Question is, Is there any way to use Z-wave protocol without utilizing any z-wave devices? using z-wave is possible in my scenario?
Buying RaZberry shield would be enough for that?, Which modem should I use to receive signals that send by Razberry?
The Z-Wave protocol is a method for communicating with Z-Wave devices. Without Z-Wave devices, there's no use for the Z-Wave protocol.
Until very recently, if you wanted to create your own Z-Wave device, you had to spend about $3,000 and sign a non-disclosure agreement to get access to the documentation and tools, and your device had to be certified before you could sell it.
The Zuno is a recent DIY Z-Wave board that enables you to create a device that speaks Z-Wave. Boards like the Razberry don't give you that capability. They only give you the capability to issue commands to the Z-Wave controller.
If you're searching for a light-weight communication protocol, check out MQTT.
