Streaming data to other platforms

yvl2009 · April 27, 2020, 1:50pm

Hi!
(1) Is possible to stream / access data on my kit to other IOT platforms, like MS Azure Cloud Platform. If “yes”, maybe some already did it?

(2) Can I use MQTT protocol to do that?

Welcome @yvl2009

That is only supported via the API

https://developer.smartcitizen.me/

In this post I explain a bit more how to do it

We also have a push API using web-sockets. However, this is only experimental

https://developer.smartcitizen.me/#real-time

Another completely different option will be to change the MQTT end-point on firmware. However, this won’t allow your device to use any of the platform features, such us the configuration tool at https://start.smartcitizen.me/

You can change the MQTT end-point here

fablabbcn/smartcitizen-kit-21/blob/2cad42e9399c4b556cac204c33fa5cfecc2a1547/esp/src/SckESP.h#L20-L24


#define NTP_SERVER_NAME "ntp.smartcitizen.me"
#define NTP_SERVER_PORT 80
#define MQTT_SERVER_NAME "mqtt.smartcitizen.me"
#define MQTT_SERVER_PORT 80
#define MQTT_QOS 1

Many thanks!
Now using API to get the data.

By the way: I expecting to recieve Grove - Multichannel Gas Sensor v2 soon.
How can I connect it to My Smartcitizen Board? What sort of updates/setting i will need to do?

So cool you’re using the API!

https://wiki.seeedstudio.com/Grove-Multichannel_Gas_Sensor/

I don’t think we have integrated it, but we can give you support with it! Have you ever coded a bit with Arduino?

At the moment, this are the sensors supported.

Hi! Thanks for reply!

well, thats sad. I was sure i would be able to connect more sensors.
BTW: on the page https://www.seeedstudio.com/Smart-Citizen-Starter-Kit-p-2865.html
it was mentioned, " Onboarding new Sensors"

Any chance the kit will add support to more grove groove sensors in future?
And, what board you reccomend to use for Grove - Multichannel Gas Sensor v2 ?

Sincerely,

Yury
