## [0.1.0] - 2023-12-29
- First working version. But without pressure sensor. Physical RS485 bus untested, but did test ModBus over TTL serial.
## [0.2.0] - 2024-01-04
### Added
- BMP280 pressure sensor via I2C
### Fixed
- Calibrated wind vane (analog input)
### Changed
- Heater of humidiy sensor only on when humidity is above 96% (was 80%). When heater is on temperature sensor also heats up, so use temperature sensor of BMP280 when heater is on.
## [0.2.1] - 2024-01-17
### Changed
- Heater algorithm updated. Idea from datasheet of humidity sensor from Temco Controls HUM-M2 humidity sensor module.
- ModBus read register 1: Scaled wind direction by 10 in order to also get the decimal position of the direction
### Added
- ModBus read register 12: Raw rain meter
- ModBus read register 13: Temperature from pressure sensor
- ModBus read register 14: Status bits
- ModBus coil register 0 : enable/disable heather algorithm
