Alternatives to Cosm (Pachube)

There are a few alternatives to Cosm for handling devices that report over the web. I'm currently playing with Sen.se (open.sen.se) and it has some really cool features that I haven't seen before. See, I'm very interested in monitoring and controlling my house. I want to be able to tell if it's too hot, what the appliances are doing, is the darn garage door open, that kind of thing. I don't want to spend months learning how to create charts, pretty switches, or automatic backups for data stores. That's why services that connect devices on the web will someday be important. Someday, services like Sen.se and Cosm will be very important to the operation of devices. Anyway, Sen.se has a method of connecting to the data I'm already sending to Cosm. By adding a feed to my Cosm account I can use the Sen.se controls and displays to monitor my house. Cool, really cool. For example, here is a graph I put together in a few minutes using their tools (scroll down past it for more):
Notice that it is almost real time? The chart will change based on the items I'm charting so you can see the latest data a minute or so after it gets posted on the Cosm site.  Additionally, it's interactive.  You can put your pointer over the control and see individual values and turn off parts of the chart.  There's also a problem putting more than one control on a blog page. They seem to interact with blogger and each other such that you can't get them to work together.  At least not yet (Sen.se is a beta site).

But isn't the chart cool?
