I want to monitor my Spa Pool controller via an Wifi shield. The Arduino controller has registers that contain counters or timers that I would like to sent to the Cayenne Dashboard. Is that possible, and if so, how?
Variables include heater ON duration timer, and other similar time/counter info.
Hi @brianhight.is,
I think this should be possible. There are various projects already created with Cayenne that control Spa pool if you search around the forum.
I hope you don’t mind, but I think a great first place to start is the Cayenne documentation.

I think the link above should help!

Hi Benny
I’ll have another, more careful look at the documentation. Thanks

No problem, let us know if you still have questions afterwards, we’re all happy to help 
Interested to see your Spa Project when it’s complete too.

The spa controller has been running well for several years. Now I want to
add remote monitoring with a WiFi shield and Cayenne widgets
Hi Benny,
The solution was much easier than I expected. I simply wrote a variable (in
this case, I used an index counter) to the widget using the code:
Cayenne.virtualWrite(VIRTUAL_PIN, index,TEMPERATURE ,CELSIUS );
I am interested in what names I can use in place of TEMPERATURE and
CELSIUS. Where can I find the list of names that are defined for these
fields? I would like to add TIME and SECONDS or MINUTES
