Unfortunately my watering system users spinners which fling the water out almost horizontal, so everything gets drenched.
Anyway, thanks for the suggestions of the Govee and the other brands. Although they are inexpensive and look to be of excellent design I decided to make my own device. That allowed me to also incorporate a light sensor, a UV sensor and a soil moisture sensor. The latter two being wanted for a different task, not orchids. This allows me to locate the control unit in the attached garage where it is dry and has mains power, with a wire to fully waterproof temperature and light sensors in the shadehouse. The humidity sensor is not waterproof and remains a problem.
In case anyone is interested, the components used are an Arduino nano microcontroller, SD card module, RTC module, some switches and LEDs for control and status, and various 5 volt sensors. Not a difficult task even for someone like myself with very basic electronics knowledge. Programmed with C or python - although most of it is already available on the net for cut and paste.
