So far I’ve used COSM and ThingSpeak and posted CodeShare samples for both, but before I try Open.Sen.se I thought I better ask if anyone has tried it and got it to work with .NetMF or Gadgeteer.
Thanks
@ Duke Nukem - I hadn’t heard of this api before, but I took a look and its very interesting. It would be great to have a driver for this.
Here is a link in case others are interested: http://open.sen.se
Here is a link to the developer docs: http://open.sen.se/dev/
After reading through the developer docs, I’m not so sure this api is that useful.
[ul]Security for authentication is a little weak.
They don’t define how device id’s are assigned and discovered.
They don’t define how feed id’s are assigned and discovered.
It appears that all devices and feeds are public, as long as you know their id’s.[/ul]
I’ve seen some very visually appealing sites put together with Sen.se and so I was interested in trying it out with an IoT project I’ve got coming up as some of the features would be very handy.
Another similar site I’ve got on my list is http://www.nimbits.com in case anyone is already using that with Gadgeteer.
Examples please. I poked around their site a bit but couldn’t really see any examples of what they were actually offering.
@ Ianlee74 - this link has some good demos of an application layer that they created to run on top of the api. This IS very interesting.

Some interesting sites based on Open.Sen.se

Cool. Have you found anything where they’re doing more than just displaying info?
[quote=“ianlee74”]Cool. Have you found anything where they’re doing more than just displaying info?[/quote]They had feature where a monkey would dance at different speeds depending on the data upload rate. They seem to have the same tweets, alerts, etc that everyone else has and they can push data out as well as doing counts, sums etc. Any feature in particular your looking for other then the dancing monkey?
Na. Just looking for a killer IoT app example.
So qualify a killer IoT app? I’m just looking for different collection engines and trying them out. Right now I have an IoT experiment going where I IoT’ed the palm trees in my office, but COSM is giving me some grief as the data feed up seems to be rather inconsistent lately ( https://cosm.com/feeds/78110 ). I know I’ve got internet connectivity etc as my palms are tweeting OK ( https://twitter.com/OfficePalms ).
Ah… There lies the problem. You never know a killer app till you see it. If I knew what it was then I would have built it already. 
I’m just looking for something beyond the obvious reading & displaying of sensor data. I’m looking for something that takes all that and really creates something new. Temperature widgets are just dashboards all over again… I see a lot of the “feel” part but none of the “act” part.

Ha! Did you just provide them with a dictionary of phrases to say under certain conditions or is there more to it?
Not sure if you are looking for somewhere that already hosts with an API but I have been playing with this and runing it on a GoDaddy virtual server.
It is basically SCADA but free for non-commercial use. You can run it on your own PC for instance as it has it’s own webserver.
Actually there are condition responses around Soil Moisture, Light, Temperature, Pressure, Humidity and I’ll add one for the Air Quality sensor I just added and random trivia responses, which you have no doubt read.
Hmm, I asked for invitation, got the code, but whatever I do, the website keeps saying “This email address has already been taken”…
As soon as my laptop is back in the game (hello Dell its why I bought the warrantee, so lets get on it please), I’ll try using Open.Sen.se for a site and when it works I’ll post it and the code of course in CodeShare. I’m thinking of building a Gadgeteer powered Sous-vide so I might as well put its various metrics up on Open.Sen.se for fun.
Hi,
I’ve been playing around with this, and have posted some sample code to CodeShare
http://www.ghielectronics.com/community/codeshare/entry/727
Hope I’ve got the attributions side of things right, with wifi code from a Duke Nukem post, and JSON classes from Wouter.
It encapsulates the mechanics of posting to Open.Sen.se in a fairly straightforward way, just needs a couple of values changed for your own API key and the ID of your feed.
So, COSM is gone: https://xively.com/pricing/
Just about when I was going to test it. It left me scratching my head now: will the same happen to open.sen.se?.. If so, then I should stop evaluating it and move to… I don’t know what. ThingSpeak? It is open source and thus has some chance to remain a free service… Are there any other options?..
That is interesting, COSM is no more but there still is a free developer account listed at https://xively.com/pricing/ but I’m not sure how much it includes. At some point sites like COSM have to go commercial or die and I suspect they know that its time for IoT to start putting up or shut up as its the biggest technology going that few are acknowledging is as large as it is given devices now outnumber humans using the internet.
There are other players who no doubt will enter this field if it really is as big as people think it is, or will be and one I hope to be testing soon (which might not be free but cheap enough and featured enough to be worth it, and who already has a key competitor with their own internal sensor device system in place)
Being open source doesn’t give it any better chance of staying free. The expense is in the infrastructure, and if open source means high adoption, then that could actually work against it by driving up costs.
