I was testing this weekend with an estimated maximum of 8000+ data points. If it slowed down from start to finish, the effect was barely noticeable, if at all. Here is an example plot on some testing I did: bbqmonitor Click on 'start monitor'. The delay is mostly because all the plot data is...

It may be too late in your design to implement but I have had amazing results using jquery/jquery.flot to plot data graphs. This all takes place with javascript on the browser. The raw data is retrieved (ajax) from a server, the data points are reformatted (trivial) for flot, and the graph is...

If wifi is a problem you might want to look at one of these network devices. PowerLine ethernet They allow you to make an ethernet connection over your home wiring. I believe the lastest Stokers allow a static IP address. Curt

1. Stoker - temperature monitoring only Curt

The temperature monitoring/recording is a standalone application (Perl) that fires at a regular interval. The presentation and control are handled by an ajax javascript browser application. It polls, via the API, temperature readings that have occurred since the last poll. The browser page is...

Thanks Gary - lots of good information After a lot of work and frustration with the Arduino board, have decided to take a different route. There is a lot of effort out there to turn embedded boards into a PC, so I thought why not just use a PC? I purchased an asus mini-ati board that I plan to...

Looks great. Can you provide a simple block diagram of the software/hardware pieces in your application. I am working on a similar application, but it's for an electric smoker. Curt

I am a little confused by the Stoker firmware release dates/versions. Is there an official release that supports json or do I have to use a beta release? If I have to go to a beta version, any suggestions on a stable version? Thanks, Curt

With the Stoker, I place the meat probe into the side of the meat and clip the oven probe 1-2 inches away from the meat. While the heat source is trying to keep the oven hot, the food will have the opposite effect, causing the oven to cool. If you place the oven probe under the food, the cooler...

What are you trying to accomplish? Remote readings, remote control? I have an auberins PID controller and it looks to me like hooking into it with some type of external interface would be a major undertaking. Curt

A browser application utilizing ajax would also allow a mobile device application to also interface to the server. Curt

For the reasons above, I recommended a browser application as opposed to a device specific application. One web page (publicly available) would allow viewing the current status, graphs, etc. Another page, wrapped in security, would allow updates to the stoker. Accesses is completely controlled...

Ah. I see. Really, it's a totally different application, because if you're going to do it that way at all, you really want to use a platform-independent language and graph generation toolkit. Written (for example) in PHP, it would then run on any system (Mac OS X, Linux, Windows) that...
