Wemos clone display testing

Chris_Holt · December 30, 2021, 11:11am

only waste your time on this topic if your feeling generous
im barely getting by with my understanding of home assistants inner workings.

the following code shows the string “smart display” and the time… but i cant get anything else to show up … i think im balsing up the printf parameters… can someoneeoint out the probably obvious mistake i have made??

What happens if you remove the if( ... has state() rows?

glyndon · December 30, 2021, 11:35am

Yes, and try adding

web_server:
  port: 80
  include_internal: true

to your config, then look at its webpage to see what it thinks those sensors’ states are. Maybe they’re not ever successfully receiving them from HA.

Chris_Holt · December 30, 2021, 11:45am

cool, knew about logs… didnt know about that one…
but it outputs this

unless im missing something it should work?

but all i get is this

Chris_Holt · December 30, 2021, 11:48am

hahaha first thing i tried… but good suggestion… im kinda at that level… but yeah doesnt affect output to screen … still just get title and time

Hellis81 · December 30, 2021, 11:52am

I don’t know if it makes a difference but you don’t have a space in "power usage%f".

Tyr this instead:
"power usage %.1f"

Hellis81 · December 30, 2021, 11:56am

Here is the issue!
TextAlign::TOP_RIGHT.

You align the text on the right side and output the text on x =0, that means the text is left of the screen.

Edit: make it TextAlign::TOP_LEFT

Chris_Holt · December 30, 2021, 11:56am

doesnt appear to change anything on the screen or the logs

Chris_Holt · December 30, 2021, 11:57am

omg… this is what i get for stealing and mutilating code lol… cheers man

Hellis81 · December 30, 2021, 11:58am

Copy pasting, the crime that strikes back

Chris_Holt · December 30, 2021, 12:00pm

cheers man, legend… lol while im at it … i get errors about no representation of the dollarsign in selected font (built in arial font) is this fixed with another font file?

Hellis81 · December 30, 2021, 12:02pm

Scroll down slightly to glyphs.

Chris_Holt · December 30, 2021, 12:05pm

cheers man… guess sometimes i just need to step back and get another angle haha

Chris_Holt · December 30, 2021, 12:50pm

legend man…im still learning and prototyping ideas, but all the great people like you out there make it possible…
