MCP9808 temperature sensor~
This feature is not included in precompiled binaries
When compiling your build add the following to user_config_override.h:
#ifndef USE_MCP9808
#define USE_MCP9808 // [I2cDriver51] Enable MCP9808 temperature sensor (I2C addresses 0x18 - 0x1F) (+0k9 code)
#endif
the MCP9808 is an I2C temperature sensor. Tasmota support up to 8 devices.
Configuration~
Wiring~
| MCP9808 | ESP |
|---|---|
| VCC | 3.3V |
| GND | GND |
| SDA | GPIOx |
| SCL | GPIOy |
Tasmota Settings~
In the Configuration -> Configure Module page assign:
- GPIOx to
I2C SDA - GPIOy to
I2C SCL
After a reboot the driver will detect automatically up to 8 MCP9808 and display sensor readings.
and in MQTT topic (according to TelePeriod):
{"Time":"2020-01-01T00:00:00","MCP9808":{"Temperature":24.7},"TempUnit":"C"}
