I think you need to develop your question because now probably nobody knows what you need.

I need to be able to set 2 relays on one hair and set a separate temperature for each

Is it possible to increase the maximum brightness of OLED and possibly turn off dimming.
It is way too small for outdoor use. Please

Hi

Can you post version with inverted relay and smaller oled 0,96, or what to change in arduino code?
Mine relay is working oposite. When it's ON on screen relay is OFF.

I have this relay:

update

added rotary encoder for local control.

Pinout:
Gpio 0 -- D3 = SDA "Oled".
Gpio 2 -- D4 = SCL "Oled".
Gpio 4 -- D2 = DS18B20 "4.7 Kohm to +3.3V"
Gpio 5 -- D1 = Relay "Set Relay HIGH/LOW level in (relayOnLevel)".
Gpio 14 -- D5 = Button "Rotary encoder SW".
Gpio 12 -- D6 = Rotary encoder A.
Gpio 13 -- D7 = Rotary encoder B.

Local control:
Botton ON_CLICK_1 = toggle auto/manual mode.
Botton ON_CLICK_2 = toggle Relay on/off "disabled if (Protected = true)".
Botton Hold 10 seconds = WiFiConfig.
rotary encoder = increases/decreases Thermostat preset temperature in steps set in WiFiConfig "0.1 to 10.0".

Supla cloud channels:
channel 1 = automatic/manual mode "ON = automatic, Off = manual".
channel 2 = relay state, manual control.
channel 3 = room temperature "DS18B20".
channel 4 = thermostat temperature.
channel 5 = increases/decreases thermostat temperature.

Added a dimmer channel that allows the thermostat temperature to be set with AT or schedules from Supla cloud between 0.0ºc and 50.0ºc in steps off 0.5ºc.

The established temperature will be half of the value set for the dimmer channel.

As an example, to set the thermostat temperature to 22.0ºC, set the dimmer channel to 44.
22.0 * 2 = 44.
198.png
sets the temperature to 22ºC every day at 22:25.


This allows steps of 0.5ºC between 0ºC and 50ºC.

It is preferable to hide the dimmer channel in the App from the Supla cloud, this channel is not useful in the App.


Pinout:
Gpio 0 -- D3 = SDA "Oled".
Gpio 2 -- D4 = SCL "Oled".
Gpio 4 -- D2 = DS18B20 "4.7 Kohm to +3.3V"
Gpio 5 -- D1 = Relay "Set Relay HIGH/LOW level in (relayOnLevel)".
Gpio 14 -- D5 = Button "Rotary encoder SW".
Gpio 12 -- D6 = Rotary encoder A.
Gpio 13 -- D7 = Rotary encoder B.

Local control:
Botton ON_CLICK_1 = toggle auto/manual mode.
Botton ON_CLICK_2 = toggle Relay on/off "disabled if (Protected = true)".
Botton Hold 10 seconds = WiFiConfig.
Rotary encoder = increases/decreases Thermostat preset temperature in steps of 0.5ºc.

Supla cloud channels:
channel 1 = automatic/manual mode "ON = automatic, Off = manual".
channel 2 = relay state, manual control.
channel 3 = room temperature "DS18B20".
channel 4 = thermostat temperature.
channel 5 = increases/decreases thermostat temperature.
channel 6 = dimmer.
