* Local temperature sensor can be used to drive watering programs/weather adaptation
* Integrate temp and humidity sensors into RainMachine
* Enable temperature sensor data source beyond weather stations
* Indoor gardening
I am working on building an automated irrigation system for vertical gardens in my greenhouse. The vertical gardens came with drip irrgiation supplies and I want a smart controller to drive the valves and need to get fertilizer injector, etc to make this all work. Since this is my first system of this type, I want to build what I need to get started (2 zones...really just one is MVP...) and have room for expansion.
For me this is part of my work on home automation and I have been fixated on the Home Assitant platform. It has some similar characteristics to RainMachine, which is what drew me here - open source basis, runs locally (not cloud dependent). But...the RainMachine product currently does NOT really work for a greenhouse/indoor use case. My main challenge is: Weather adaptation feature is dependent on weather stations and not local sensors. I have a personal weather station, but it is outside (because local weather services are not accurate enough to reflect local conditions, especially wind). I have built local temperature sensors with wifi-enabled microcontrollers...very cheap and effective.
So it seems that my possible path with Rainmachine is:
* Use the automation platform (or IFTTT) to force a program to run based on temperature levels
* Get some code written to add my local temperature sensor to the "Deverloper" tab of weather stations.
My non-RM path is: build my own controller with a wifi-enabled microcontroller ($5) and a relay and needed adapters. This is definitely cheaper, more of a hassle, and I can use some community code to do evapotransporation calculations. However, I'd really like to press the easy button here...c'mon RM!
