Where are you seeing the HTTP Error?

Hi there

That’s great. Thanks very much.

To answer your first question in the IDE if I go to My Devices, choose the device and make a change then the webpage blanks. I then hit [F5] to refresh and the thing throws an HTTP error.

As for the code that you posted, thanks again. Copy Paste results in an error which seems to be a UNICODE issue around the quotes. Do you know of a magic way to get the code copied across?

Hey guys can u help?got myself a sir321 i cant copy and paste any of the code within the threads here as it comes up as an error within the "create device handler"box, so i have gone to git hub and used @Ross_McCarthy dth, the device handler is created fine, i then go to the sir321 which has been added via the smarthings app as a “zwave switch” use edit and then change the “type” to the new device handler “sir321 immersion controller” i press update and it says update and refreshes and says updated but it doesnt update it remains as a zwave switch type, to be sure i changed the type to a few other different zwave types just to see if it changes the type and it does,its seems it just wont accept the new device handler type,for the moment i have it working as on off switch with the zwave sw type,any advice would be appreciated very much,

You need the one I posted. But it needs redoing so it works. I might try posting it to git hub instead.

Can’t do it for a couple of weeks though.

Hey there,
Thanks very much for your reply, no worries at atall I can wait for that no problem I have no idea of coding so I wouldn’t know where to begin.thanks again

Any joy bro? no pressure just wondering if it’s still on the cards thanks

Yeah. I’m in the same boat.

Would be great to be able to set the immersion to run for 60 minutes rather than plain on/off

Sorry I have been out of the country and forgot. I’ll do it tomorrow. I might fit hub it for you.

OK, so I have applied this and at least it is allowing me to change the device. I don’t have temperature sensors installed in my switches.

I don’t see any timer settings - is that expected? I would be great to be able to set 30mins, 60mins, 120mins or ON

No the commands are not usable in ST as they are not exposed by Samsung. I tried and tried and just failed.

The new coding might now support it but not looked. But a selection of push buttons and webcore pistons would do that.

Oh. Adding the temp sensor is useful. That way you can only have the immersion come on after the temp has dropped a significant amount rather than little top ups.

Also on long holidays you can use it as well OST protection.

Yes, I’m happy with the webcore piece. Thank you

Hi Mike

This is the one that is working for me.

I notice that one of the capabilities for the device is schedule. When I look at this in WebCore then set schedule is exposed. Do you know how to take advantage of this - I naively tried Set Schedule 30 and it does not appear to do a whole lot :slight_smile:

It might be different now but the set schedule code was not supported by ST due to the type of request it was. Changes in the code sets from ST might allow this now.
