QUESTION
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?
...ANSWER
Answered 2018-Jun-13 at 18:09The 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.
QUESTION
I am getting this error: 'int' object is not iterable
for the following codes which is meant for sending sensor values from my Raspberry Pi to Ubidots. I have read similar questions and answers but I cannot figure out where the error lies.
ANSWER
Answered 2018-Jan-17 at 13:46From the documentation for requests.post()
:
Parameters:
url -- URL for the new Request object.
data -- (optional) Dictionary (will be form-encoded), bytes, or file-like object to send in the body of the Request.
It looks like read_adc()
returns an integer, so what you're passing as the data
parameter is not what post()
is expecting.
I'm not familiar with Ubidots, so I can't tell you exactly what format it expects the post data in. You'll need to find that out and provide either a dict
or bytes
object formatted appropriately.
Edit: Per your comment, if you need to send JSON data, then prepare the data structure as necessary and send it with:
