I vote for solcast also. In home assistant I can monitor Forecast.Solar also and that one is (way) less accurate. I have the experience that, for me, solcast has a better prediction for all day and adjusts (better) during the day. ---

Hi How do i combine the 2 sites to one total value? Want to use the sum of the 2 arrays to get a more “real” forecast, have 2 directions, south and west. Must be rather simple, but can’t find it. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/b/ab14e7523a6d73269934e63e541bd05f643dd07a.png) ---

Just use a variable and make a flow to make the sum of those values. (which triggers when one of them changes) ---

Hi, I followed all the steps for Solcast (register, add values of my PV system,…) and I have an API Key & resource ID. I also set up the flow for the “fetch solcast update”. Unfortunately I get API errors: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/4/1473a22c5402e8775a9481bec1f14e2e3c9c134a.png) Any toughts? Regards, Tim ---

Send me a diagnostic report and I will check ---

I retract my statement, it does work now. I don’t now, I waited a few days and created a flow for “Fetch Midnight update”. It seams that just pressing the on/off button on the device itself wasn’t working to get updates (instead it showed the error) after the device creation. ---

Is Forecast.Solar down? As of 15:00 today I’m no longer receiving any data 🤔 ![IMG_5551](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/b/abee2ece1cbdab3a14fab922793469e898c52292.jpeg) ---

Any idea what could be wrong? I’ve also tried creating a new Forecast.Solar device, but it still doesn’t pull any data in :x ![IMG_5552](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/e/0e49dd598ddf06056d6ba8e0632f33f54250e6c2.jpeg) ---

Try a homey reboot, that sometimes fixes a lot of things. Or wait a day. If it doesnt work send me a diagnostics report ---

@Pieterv123 Reset the app, rebooted Homey, but still no dice… API calls are OK, but no information is coming in. Weird, because it’s been working great for 9 months now. Diagnostics: 0ba3ec3f-620a-496f-80e3-370c7246b901 ---

It has nothing to do with the app, but Forecast.Solar returns: invalid location you check with your location: [https://api.forecast.solar/check/4.8/52.36](https://api.forecast.solar/check/4.8/52.36) ---

Huh; that’s weird. Where is the app getting the coordinates from? If I check the location of Homey, it shows a correct pin 🤔 Or is it a problem with Forecast and these specific coordinates… ![IMG_5555](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/8/885b3d0454bcf104914bc28a9c3c8db88c8293f5.jpeg) ---

Mhhh. It also gives an error if I need it the coordinates to Amsterdam Central Station [https://api.forecast.solar/check/4.899431/52.379189](https://api.forecast.solar/check/4.899431/52.379189) Looks like there’s an issue with Forecast.Solar then? ---

I think so. It uses the location of Homey. I cannot check for the moment as my Homey is dying… [Previous page](https://community.homey.app/t/app-pro-solar-forecasts-solcast-forecast-solar/46842.md?page=12) [Next page](https://community.homey.app/t/app-pro-solar-forecasts-solcast-forecast-solar/46842.md?page=14)
