Could you please provide the source code for the same, but with regulation at least 0.5C. Super with 0.1C.
Thank you
Thanks for a good job on this project. In my project I also want to use 0.1C resolution.

Hello everyone,
thermostat based on the elmaya project with a setting resolution of 0.1C.
SSD1306Wire display // D3-SDA D4-SCL ----- 0.96 Oled ---
int relay_pin = 5; // D1
int ds_pin = 4; // D2
int button_pin = 14; // D5
#define button2_pin 12 // D6
#define button3_pin 13 // D7
I changed the relay code for my own needs, maybe it will be useful to someone else. Settings every 0.1C and adjustable hysteresis. Controlling the thermostat every 0.1C and added a hysteresis setting in the range from 0 to 10C every 0.1C from the application level. The hysteresis is also visible on the display. There are three physical buttons. One click Auto/Manual, double click turns the relay on or off manually if the thermostat is set to manual. The other two buttons for setting the temperature, when pressed for a long time, change the temperature quickly. Hysteresis set in the application using a switch or dimmer.
For the main part of the code thanks to elmaya.

Hello, can you make adjustments to the displayed temperature on oled in the version with buttons?
shows 1.5C too much

this changes the display in the app and not on oled

quote from datasheets:
"...Benefits and Features
• Measures Temperatures from -55°C to +125°C
(-67°F to +257°F)
• ±0.5°C Accuracy from -10°C to +85°C..."

in my opinion your DS18B20 is enclosed in a case and is heated by a microcontroller or power supply or something else.
if it's not closed, it's broken.
However if you want a fix in the code,
find:
class TermostatTemp : public Supla::Sensor::Thermometer
{
public:
TermostatTemp() {}

void onInit()
{
channel.setNewValue(getValue());
}
double getValue()
{
return ThermostatTemperature;
}
void iterateAlways()
{
channel.setNewValue(getValue());
if (millis() - lastReadTime > 2500)
{
lastReadTime = millis();
actualTemp = DsTemp->getValue();

change:
actualTemp = DsTemp->getValue() - 1,5;

I have the sensor on a 15cm cable, I tested 3 sensors and I have the same on each, it is possible that they are of poor quality.
the given example does not match "supla_Termostst_oled_dimm_V04.ino" and this is the software I use.
