Thanks to a data feed courtesy of an IBM broker, [test.mosquitto.org] now
|
|
publishes information on energy generation and demand in the UK (in the energy/
|
|
topic tree). I think this could be used as a great demonstration for coupling
|
|
MQTT and the web.
|
|
|
|
# The challenge
|
|
Create a web based report that takes energy data from the broker over MQTT and
|
|
displays it in interesting and useful ways. Alternatively, an Android/iPhone
|
|
app would be ok, but web based is the preferred option.
|
|
|
|
# The rules
|
|
There are no rules really. Having said that, I'd be most pleased if the end
|
|
result was something that other people could learn from. There are bonus points
|
|
for solutions that work where a web proxy is the only internet access. If you
|
|
want to use new or unusual technologies that's fine.
|
|
|
|
# The prize
|
|
I'm afraid there is no tangible prize - I hope you'll be content with your work
|
|
being shown here and the respect of your peers.
|
|
|
|
# Some suggestions
|
|
Google charts is definitely worth looking at for generating the actual graphs.
|
|
Some examples of what you might show are:
|
|
|
|
* Pie chart of generation source
|
|
* Gauge of current mains frequency
|
|
* Historical graph of electricity export amount
|
|
|
|
I look forward to any and all responses!
