I’m trying to fetch my P1 energy data from a Domoticz installation using a script. ```auto // Create the request const res = await fetch( 'http://192.168.1.81:8080/json.htm?type=command¶m=getdevices&idx=29'); if (!res.ok) { throw new Error(res.statusText); } // Get the body JSON const body = await res.json(); ``` When I try to run this, Domoticz seems to deny the request because of authorization issues: ```auto ——————————————————— ❌ Script Error ⚠️ Error: Unauthorized at fetch-domoticz-p1.js.js:4:9 at processTicksAndRejections (node:internal/process/task_queues:96:5) at async HomeyScriptApp.runScript (/app.js:364:22) at async Object.runScript (/api.js:30:22) ``` Reading up in the [Domoticz documentation](https://wiki.domoticz.com/Domoticz_API/JSON_URL's#Authorization), it says I should encode username & password in the “Authorization” HTTP request header. Encoding username/password is no problem, but how do I get these in the request from Homey? In the end, I want to connect this data to the data from my solar panels to create something like this (screenshot from domoticz, don’t need the graphs but do need the data): ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/7/b700a047b210edbb80cc1842b90ce883620671f6.png) ---

Maybe this is helpful (open these posts to view the shared scripts): > [@Omlet Smart Automatic Chicken Coop Door: Automation using Homey Script](https://community.homey.app/t/omlet-smart-automatic-chicken-coop-door-automation-using-homey-script/115988): > > I faced the issue of not being able to control this door through automation since it is only controlled by Google Home normally, and since Google Home wont allow any sort of automation for device type “Door” for security reasons, we simply cannot open/close the door through flows or even Google Home routines, we are stuck with manually opening/closing the door, which kinda sucks. Luckily, Omlet provides an API (Open API 3.0) that we can use inside Homey Scripts to open/close the door and fetch … > [@Homeyscript for bearer token](https://community.homey.app/t/homeyscript-for-bearer-token/47819/6): > > It looks like the issue is with fetch() behaving differently.

You should be able to pass in the headers to fetch: ```auto const response = await fetch("https://example.org/post", { headers: { "Authorization": "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==", }, // ... }); ``` ---

Whitelist your local subnet in the domoticz setting: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/b/3b7bb06ac8f2955f6cb062a9fee3e7f3f7f51539.png) ---

That is actually not a bad solution. Bit of a security breach, but not too bad since my domoticz server should not be available to the outside world anyway. Thx! ---

Frankly, Domoticz is a pretty much dead. Still have it for the much stronger 434Mhz frequency hardware (rfxcom). ---

That is exactly what I use it for though in my case it goes back to 2020. It runs on a RPi3 that doubles as a music server. Unfortunately, Domoticz refuses to fetch information from my PV installation, which was a breeze in Homey. Therefore, the combination of the two. Anyway, Domoticz has been next to dead for years now. Not much development is going on anymore, things are dormant. As long as i works, it works.
