Hello, very nice! Could you share the code you used for this? It’s quite interesting. Also, the STL file for the case in this combination? Thanks in advance.
Sure, it’s definitely a work in progress, unrefined and not optimised since I’m just prototyping stuff with it - but here you go

To answer your question directly, yes. I needed to change the pin from GPIO9 (LCD_BL) to GPIO21 (RGB LED)
I could then use output.set_level to change the brightness of the screen.
output:
- id: oledbacklight
platform: ledc
# pin: GPIO9
pin: GPIO21
max_power: 1
min_power: 0
I could then link this to a luminosity sensor to change the brightness value depending on the surrounding light levels- (similar to the below).

Any chance you can put this info in a repo? It would be great to be able to keep up and test out your progress on this.
Sure

Much appreciated. I had never used ESPHome until I saw this post, and I was not looking forward to having to do any C++, so seeing that getting this thing working in this manner was a pretty huge deal, lol.
Edit, I am going to have to try and strip all that down to the bare minimum and work my way up from there. I tried to remove/change the obvious things that were non-existent in my setup, but have yet to get the backlight working. I can tell something is displayed, as I can barely see a small icon, but that’s about all I can tell that is going on.
Is there an example somewhere of a minimal template of just the necessary things that one could build up from, that anyone is aware of? Perhaps from a different but similar device?
Hey, that’s very nice! How did you connect it? Can you share a photo or a diagram so that I can connect it too?
can you share this file pleas ?
i have this erro code ?
Could not find file '/config/esphome/fonts/arial.ttf'. Please make sure it exists (full path: /config/esphome/fonts/arial.ttf).
I don’t use it in the actual code, it’s legacy, so you can either remove the reference or find it online from any of the numerous free font sites.
Couldn't find ID 'roboto24'. Please check you have defined an ID with that name in your configuration.

this erro next ?
It’s defined in the fonts section of my file (line 149). So you will need to check what you’ve done.
Big thanks to @dgaust for sharing your code.
I stripped it back for others to play with.
Main changes in my code
- backlight to come on upon boot
- backlight pin changed back to 9
- added NFC reader
- removed arial font
I am no coder, but this should be able to help those just wanting to build from a starting block.

workshop_volume is an entity in my HA setup.
Only left it in there to show how dgaust updated the values when the page shown was changed.
Has anyone been able to get the RTC to work. I have found a few randomize almost documentation-less examples but not been able to get them to work.
I think the issue is esphome assumes a type that these components have not implemented and even their examples will not compile for me.
I have the paper too. Anyone know w bit more about the guts here to understand what is happening? I want to use the RTC because the yaml I am working on runs this thing off of battery as a portable remote. I want to shut things down and keep the wifi off as long as possible.
I had not, but I am playing around with it since it looks like it uses the PCF8563 RTC chip PCF8563 Time Source — ESPHome
The below appears to work and will display (a currently incorrect) time
esphome:
name: m4dial
friendly_name: M4Dial
on_boot:
then:
# read the RTC time once when the system boots
- pcf8563.read_time: my_time
- text_sensor.template.publish:
id: template_text
state: !lambda |-
char str[17];
time_t currTime = id(my_time).now().timestamp;
strftime(str, sizeof(str), "%Y-%m-%d %H:%M", localtime(&currTime));
return { str };
time:
- platform: pcf8563
id: my_time
address: 0x38
# repeated synchronization is not necessary unless the external RTC
# is much more accurate than the internal clock
update_interval: never
- platform: homeassistant
# instead try to synchronize via network repeatedly ...
on_time_sync:
then:
# ... and update the RTC when the synchronization was successful
- pcf8563.write_time: my_time
- logger.log: "time synced"
text_sensor:
- platform: template
name: "RTC Sensor"
id: template_text
There are three i2c components on the internal bus at
0x28 is the RFID scanner
0x38 appears to be the RTC chip
0x51 is something I haven’t looked at yet

It’s starting to look more and more that I will have to learn some c++, and the esphome codebase, to turn these ft3267 drivers into a custom esphome component to get the touchscreen working since the pull request isn’t getting much traction
Same in regards to the screen, it is doing something curious where it needs the entire (seemingly) esphome codebase and compile time takes forever. I started to pull it apart, but it is working so…kind of meh.
I know C but never made a component. Looking at the shell of them now, but it is less about knowing C than knowing the libraries and structures expected here.
Hey, have you managed to get the RFID sensor working to add the new card and make the current card work?
