I just bought a pair of CT50e thermostats (with wifi USSNAP radios) for the house. The stats have a published API Here.
I think PH should be able to GET/POST information to and from the thermostat. Has anyone ever used these before with PowerHome?
I am having some initial difficulty getting these set up on my network, so if anyone has any personal experience, it would be greatly appreciated.

I have my wifi Tstats hooked up. They seem to work well. I am able to RECIEVE data off them. For example:
ph_getitcurl("192.168.0.50/tstat",20)
returns
Execution time: 2.244 seconds.
The formula evaluates to: {"temp":77.50,"tmode":3,"fmode":0,"override":0,"hold":0,"tst ate":0,"fstate":0,"time":{"day":2,"hour":19,"minute":4},"t_t ype_post":0}
I am now reading the API document (link above), trying to figure out what PH formula will let me SEND a command to them. For example, from the API document (to turn the Fan On):
2.5.5 Set fan mode to ON
The following curl command sets the fan mode to ON.
$ curl -d '{"fmode":2}' http://192.168.0.50/tstat
{“success”: 0}
I tried
ph_posturl1("192.168.0.50/tstat","fmode:2",0,20)
but the Tstat give a bad response (see below).
What else can I try?

This didn't work either:
ph_sendsocketdata("192.168.0.50/tstat",80,"{fmode:2}")
How can I tell what port these Tstats use???

I guess I could also just download and install the cURL executable command line tool for windows.
I was hoping to find a "cleaner" approach....will keep looking from within PH.

I've got something sorta set up with a CT80. I've been somewhat lazy in my implementation, so at the moment it's just changing the global values I made for the temperature and status in PowerHome, but PowerHome isn't even doing anything with that data yet.
I actually had already set up a data collection thing, so I have a PowerShell script that runs once a minute and queries the thermostat for all the data and writes it to a MySQL database my really simple home status site pulls from (http://www.lizaoreo.net).
Then I wrote a simple C# app that runs in the background and polls the MySQL database every minute and updates the global variables for the temp and stuff. I don't know enough to know how to make a plugin that acts like a thermostat using the PowerHome built in stuff, so this is how I did it.
Let me know if you're interested, I can share my code and stuff if you're interested, though you seem to have the read part figured out in a different way from me.
