Description
Description
The Easy Reticulation is a low cost wifi enabled reticulation controller based on an ESP8285 Module, it has 4 relays that output to 4 solenoids at 24vac. That means it is suitable for 1 x master solenoid and 3 stations. The wifi control module is powered by the 24vac transformer that powers the solenoid so only one supply is required. As most reticulation system run on 24vac you can use an existing system's power supply, installing this one along side or inside if there is room to enable an existing system up to 4 solenoid to be controlled via wifi. It has a M205 fuse to protect outputs and the controller and a real time clock DS3231 so that in the future it could be programmed via the Arduino IDE to be a stand alone device, it is currently designed to work with Home Assistant.
I have installed many large and expensive reticulation controller many of which are not even wifi enabled for landscapers and most of them only have 2 or 3 stations in use, some only one station. Most people set their controller and thats it they look at it again only if something isn't working, so why have a big complicated box and lots of stations. I made this to be easy to use, low cost and wifi connected to I can connect it to my Home Assistant setup.
