That’s a great idea! I could write my own script that accesses my soil moisture sensor and calculates a % watering level. I use an OSBo so I could then host the script on it. I can create a program that uses a weather adjustment and set the weather adjustment method to manual. My script will provide the % watering level.
Two questions:
1. I believe the OS firmware polls WU at some interval. How can I poll my custom script instead of WU?
2. If I have multiple soil moisture sensors, how can I differentiate between them? For example, I might have a program and a soil moisture sensor for the potted plants on my deck and also have a program and sensor for my vegetable garden in the ground. The pots will require more frequent watering than my vegetable garden.
