Listen to HTTP get reqests

  • openHAB version: OH3

I have a in garage remote PI0W runing heating app using DS18b sensors . On it , is Python script scaning for new sensors in /sys/bus/w1/devices/ and tracking temp changes and using HTTP GET it’s sending readings to in house PI3’s ip addr (that also has heating app ), so I have outside temp correction for home heating . And to be able to read all temps in one place (home PI heating web page) .

I also have same setup in country house , possibility to remote turn on heating and reading the temps .

Is there any way to read those HTTP reqests in OH3 ?

Thanks.

OH can issue HTTP requests with the HTTP binding or the sendHttpXRequest Actions.

OH defines a REST API that lets external things send updates or commands to OH Items, but those use POST and PUT, not GET.

Beyond that I know of no supported way to have OH listen for arbitrary HTTP requests.

You can have a look at this:

[webhook] New, very simple binding for listening incomming http requests

Hello, I have scratched a simple binding for listening to incoming http requests. What problem does it solve? There are quite a few devices which are able to perform http requests on a given webhook (like Synology Surveillance Station in rules or some intercoms/ip doorphones like akuvox). Those httprequest cannot be simple utilized in openhab straight away. You could translate it at nginx level from the simple form of http get/post those devices can perform to openhab REST APIs or create a si…

The other way is to work with Node-RED to receive the http requests and link it to openhab with “node-red-contrib-openhab2” for example.
