Help.
Elmay, can you tell me the reasons for the Error message when converting the USB power supply to the power supply?
Connected as in the picture:
the ERROR Conimukat appears

What is this, what does it mean?
The display shows errors as "E" with a number.

I am sorry if I described it poorly.

What cable length do you have for DS18B20?
test with a lower resistor of 2,2kohm for the DS18B20 probe.

80 cm long nan sensor cable.
A resistor like the three design in the first post 4.7 kohm.
Are you suggesting inserting a smaller 2.2kohm ??

yes, reduce the resistance of 4,7koh or use 2 in parallel,
you have a problem of electrical derivation, you can also connect the GND of the wemos to earth.
Perhaps it is also possible to solve it by turning the plug around (220v).

elmaya - Is it possible for a cannon project with e.g. a display like this: https://pl.aliexpress.com/item/32994189 ... hweb201603_
I think it would be clearer and more readable than Oled.

By the way - a tile is created.Of course, this is still a small fix.
Everything can be assembled from ready elements and modules.
How it will come and act - I will have a pair to give away.
Of course, I'd like to put a 20x4 display .... lol ..

What and how do you want to see on the 20x4 Display?

I think I wrote the other way around. it was about 4x16 lib 4x20. I think that what is enough for the Oled display, but spread over 4 lines. This display seems to me to be more readable.
For example :
1. CURRENT TEMPERATURE: ----.
2. REQUIRED TEMPERATURE: ----.
3.WORK MODE: MANUAL / AUTOMATIC
4. DEVICE STATUS: On / Off, next to WiFi network status

Hello
I built a thermostat based on soft: Supla_Termostst_oled_H_C_0_96_DOUT_16Mbit.bin with display.
Everything works, unfortunately, the display is dead. The displays have two pieces with SCK and SDA markings probably because if I can ask you to generate a bin file for these displays I do not want to throw them in the bin because they will not be useful for anything else.

Can you share GERBER for the tile?
