I’m starting a greenhouse (for vegetables, I know what you were thinking) and have been using a multi sensor to monitor temperature and humidity. I was wondering if anyone had created a smartapp or device handler that was made specifically for this application. I’d like alerts when temperature drops close to freezing or above a certain temperature. Same for humidity, and maybe some measure of light too. Then some some switch integration to power a heater, exhaust, grow lamp to supplement sunlight, etc.
Anything like this in existence?
