Hello,

Does anyone know if it's possible to control Wiser from Loxone? I don't need granular control but would love to be able to activate away mode via Loxone when the house is empty or the front door is open for example.
I know it has an IFTTT channel and that some chaps working on OpenHAB have discovered some sort of API (https://pypi.org/project/wiserHeatAPIv2/) to use with it.

Disclaimer: I don't have Wiser.

The documentation here makes it look quite simple to integrate:

2/ make an HTTP virtual output that does a POST request to http://IP_ADDR/data/domain/System/RequestOverride with payload "{"type":2,"setPoint":100}" to enable away mode (10ºC min temp in that example), and "{"type":0,"setPoint":0}" to turn it off again,
 include an http header of "Secret: <your secret>"

AIUI in Loxone you can send  the "Secret: <foo>" customer header by putting it in the (oddly named) "HTTP Extension for ON/OFF" fields. (The POST payload obviously goes in "HTTP Post Command for ON/OFF")

HTH

Hey thanks for the quick reply! I hadn't seen that page when searching. I'm not brilliant at coding so can I try to take this step by step?

I make a virtual output and set the address as http://192.168.xx.xx/data/domain/System/RequestOverride

Then add a virtual output command adding {"type":2,"setPoint":100} or {"type":0,"setPoint":0} to it depending on the command I want to send.

Is that correct? I'm not sure where to add the secret string though.

Oh hang on, Ii have just seen your comment about the secret string, story about that. I'll amend the config and test.

The secret goes in an HTTP Header, which appears to be what Loxone calls a "HTTP Extension" hopefully others can confirm (I've never actually used it, but I've done plenty of HTTP coding over the last 3 decades :-)

If you can install curl on your computer, I'd always test it there first before messing around in the Loxone UI.  Example:

curl --header "Secret: INSERT_SECRET_HERE" \
  --request POST \
  --data '{"type":2,"setPoint":100}' \
  http://192.168.xx.xx/data/domain/System/RequestOverride

Apologies for going quiet, w*rk got in the way.

Below are the various ways I have tried to make the VO work in Loxone without any luck.
Not quite sure how to run Curl but I do have a Pi that I can install Node-Red on so am going to look at that and follow the instructions on knightnet to see if I can get it working via that.

Virtual Output

Address                              192.168.xx.xx/data/domain/System/RequestOverride

Close connection after sending   Checked

Separator                                      ;

Virtual Output Command

Command for ON                         

HTTP extensions for ON              "Secret:secretstring"

HTTP Post command for ON      {"type":2,"setPoint":100}

HTTP method for ON                   POST

 


Command for ON                         

HTTP extensions for ON              "Secret: secretstring"

HTTP Post command for ON      {"type":2,"setPoint":100}

HTTP method for ON                   POST

 

 

Command for ON                         {"type":2,"setPoint":100}

So, I managed to get this to work in the end by using webhooks in IFTTT. As I don't need instant actions this is a great workaround. Hugh at Loxone realised that the HTTP method for ON needed to be GET rather than POST. If anyone needs the config/instructions I can post them. I expect it may also be worth trying out Joth's suggestion with a VO but using GET instead.

Hmmm you can't send payload in a GET request (unless it's URL encoded, but this seems very unlikely) so other than the initial secret retrieval (which is indeed via GET) I'm skeptical.

and
it actually seems to use PATCH (not POST or GET). Sorry about that! 

And, not sure of Loxone has any support for issuing PATCH requests?

Joth,

At this point I should mention that I can use Crestron's SIMPL Windows and Loxone Config, I'm pretty damn clueless when it comes to JSON, HTML etc. I can follow editing instructions fairly well but never even tried to learn either so I bow to your superior knowledge.
Here is what is working for me using webhooks/Wiser in IFTTT (after setting up the webhook to control Wiser away mode). Obviously it would be better to use a VO and keep everything inside my network, as I said I will experiment with that but will involve me blindly pasting info into different fields so may take some time!
One thing it may be worth mentioning in case anyone is attempting something similar is that the below didn't work when I entered this info into it. I had to make a second one before the miniserver could communicate with IFTTT.

VO
Close connection: checked
Separator: ;

VO Command
Command for ON: /trigger/wiserlaters/with/key/secretstring
HTTP extensions for ON: 
HTTP command for ON:
HTTP method for ON: GET
