Http GET command to change device status

[emmett]

Hi,

I am trying to write a script that will send a http GET command then depending on the result either turn a device on or off. The http page will either have a 0 for off or 1 for on. Any thoughts?

Thanks,
Emmett

This would be great if it worked with Xively

Last week I started messing around with Arduino's - they are fantastic - but not much integration with HS - if this could receive and send commands to Xively and or thingsspeak

It would be good to use an API key for security and id the event you want to change or publish along with a value.

Http GET command to change device status

You could create an asp page which links to homeseer, and have variables passed to that asp page which trigger or do something.

You would have to make this yourself but I do believe there is a tenhsserver script which does something similar

You can use the command hs.urlaction to do a GET and examine the result (the reply string will be the result), example syntax is in the help file.

I and others have been doing stuff with Arduinos or other micro controllers in HS for a while (to me that is what HA is all about). I did think of either creating a big project thread with simple example projects of linking them with HS...if you have anything specific I could see about creating a thread with some instructions (if I can do it myself, set myself a challenge now). With stuff like http://www.indiegogo.com/projects/9-...rn-electronics they are very inexpensive way of getting IO into HS.

Ok thanks! I will try and use the hs.urlaction. I am trying to interface a Raspberry pi and I have magnetic contact sensors connected to GPIOs and would like the status of those to reflect as HomeSeer devices.

Return Value

You can use the command hs.urlaction to do a GET and examine the result (the reply string will be the result), example syntax is in the help file.

Here is what I currently have.

Sub Main
dim s
dim data
const website = "http://10.0.0.50:8000/GPIO/23/value"

s = hs.URLAction(website, "GET", "", "")
End Sub

How would the return value be written so if the value = 1 it is on and 0 for off? Where does the hs.URLAction return the value?

Thank You,

Emmett

I did set some outputs from the R-Pi using some python web server script and the MCP23017 (IO expander), inputs were a bit of a pain in the proverbial as there was always a delay on polling them if you relied on HS to do the polling. If you did the polling in a python script you could combine it with the (rather excellent) TextSeer plugin that could respond to a HTTP command into HS and set the devices.

below s= hs.URLAction add this line

hs.writelog "Test", s

and tell me what gets put in the HS log...

heh - I just backed them today for 1 board.

I'm in the queue for two but might up it another considering he has said that this will be the only run, shame really as it is going to be a good deal but guess you can't make a living out of it.

This is the result. It looks to be working. How would I then go about turning my virtual device on or off depending on the result?

It would be something like

s = cint(s) 'this just converts it into an integer

if s = 1 then
hs.setdevicestatus "C1", 2 'this sets C1 to on, change C1 to suit
else
hs.setdevicestatus "C1", 3 'this sets it to off
end if

I know it requires hard programming in the Raspberry Pi / Arduino but wouldn't it be better to have it work the other way, e.g. the Device tells the Homeseer server to change the value of a specific device code, rather than have the homeseer server poll the Raspberry Pi / Arduino device every x amount of time. Then you can move away from having to pull the results and have the device push the status when it changes accordingly.

Example: Door 1 - 5 Sensors connected to Arduino + Ethernet. When door one is opened after x seconds the Homeseer server pulls the result and determines that it has changed and updates the device status accordingly, if you have a delay of 1 - 5 seconds between then you could miss this and have a pause, whereas if you have the device push its status to homeseer through a URL then as soon as a status changes, it would be updated accordingly.

Just my two cents worth, but it would either require you to know the device code, or to have an ASP page where you send the sensor number and in the ASP page then match that to the appropiate devicecode.

end if

That worked perfect! Thank you!
