Hi guys, I have created a virtual device that should show me the % charge state of my solar battery (info comes from Sofar inverter - sofar app on Homey). I think I’m doing something wrong because it’s not working :slight_smile: Here is my simple flow: [image] I think there is something I’m no…

[image] Peter_Kawa: $value/100 You are the man :slight_smile: Thanks! This worked perfectly

I think the problem is that you are using 2 tags. At this page is showed how to use virtual devices. https://community.homey.app/t/howto-set-a-value-to-a-virtual-device/45883 There they use examples for temperature. I tink that you must use neasure_battery as tekst. But it depends on the capabi…

This works! Thanks :slight_smile: However: the virtual device shows a battery logo: [image] But I would like it to display in a numeric value in %, do you know how to get this done? Thanks for the assistance!

Ok trying to get this to work :slight_smile: I have this for the moment, but I need to fill in a BLLExpression (but the field is greyed out? [image] [image] Am I on the right path? :slight_smile: Thank you!

Nice! Try using a Number field. The percentage is a numeric value (as shown). “React” can be left empty (you can’t command a battery level).

Nice! Almost there! :slight_smile: Now the only issue is that the value in the tile shows 2400% instead of 24% that is represented when you click the tile… Thanks for your support!

Looks like the app is showing a 100x value, the web interface shows the correct value…

The issue is: homey works with 0 to 1 values internally, and in flow cards. Somehow when you use % as unit, it multiplies the value with 100 to convert it into a % value. The battery reports 0 to 100 probably, so you’ll have to add a / 100 (divide by 100) calculation. On top of my head you’d enter…

How do you make the BLL field available for input?

Don’t know, just enter something and see what happens What Joske522 described as ‘grayed out’, this one: [1000035266] isn’t grayed out, the red line even points to it being a mandatory field. Kay, is your Q about number fields, or text fields? Do these examples make sense? [1000035262] …

In that case you’ll need to use an advanced virtual device. Often you even don’t need flows to update the device values.
