![]() So, I came with an idea to open the sensor and somehow connect it to a rain sensor like thisīut, I don't know how the sensor works. the kit reaction is too slow, because the sensor reacts only when the rain is too heavy (5 liters/sqm) it is OK for an irrigation system where time reaction doesn't matter but for my attic will be a disaster. ![]() and the wireless sensor I'm thinking this will fit perfect with my needs, but it has problem: And because this package has a controller with battery indicator, signal strength. I'll tell you what my project is: I need to close automatically an attic window when rain starts. I searched a lot regarding projects with RainBird WR2-RFC, but I found just your post here.Īs I see it is an old project, and I hope you are still present in this forum. Pretty easy when you don't need a display or buttons! I hope to be able to program the relay station using MicroPython but if that proves to be too buggy I'll use Arduino instead. Other than that, I'll need a regulated DC power source. Another option is to use an I2C port expander to control the relays which would take care of the buffering too. I don't think the current output capability of the chip is enough to drive the relays so I'll have to use a buffer chip. It should be perfect for this since it has 9 GPIO and I have 8 sprinkler zones and a rain sensor. I'll use JSON for the machine-to-machine communication.įor the remote relay control station, I want to use the fully broken out ESP8266 module from to control the relays. I'll need to read through the code and find all the places where the actual hardware is being controlled or read and modify that. Another plus is that the OpenSprinkler Pi project is programmed in Python. I have one already and it should have enough horsepower to expand into more home automation tasks I have planned. A RaspberryPi will be the main controller for two reasons. I want to break this link and have the hardware control separated from the software. The OpenSprinkler project currently has the software and hardware control on same board. This is basically a software project with a small hardware component.
