yeh if they’re under the lawn i would def run a cable to the side and have an outdoor station monitoring and powering them all.
OK for me doesnt go below 6 in winter where i live
I have 24V DC running around my fence line already so I just include a 24v to 12v dc-dc converters in all my outdoor projects. I will use it in my garden to start with. I have a potted garden so i will have it connected to a water proof station on the fence and a long cable that i can insert in to one or move around.
But yeh pretty excited as I got the early shipping one.
I have one of these already but i havnt had a chance to play with it all winter. I got the rugged version.
Hello Jamin.
I tried to replicate your project adapting it for my purpose, changing water price in Ron and the tap state to ON=GPIO HIGH and OFF=GPIO LOW in order not to keep the relay armed most of the time.
Everything works fine, but I could not tell from your picture what the WARN led and RTC clock widget do.
My kind requests are:
1)Could you please explain to me what they do and what (virtual) pins connect to them (if applicable).
2)I would like to add adjustable timers where I should be able to set the irrigation to trigger by itself applying the default limit. (like 1-2 automatic runs a day). Do you have this implemented in a sketch or how do you suggest I should do that?
Thank you very much for your time and this helpful project.
Florin
Hey not sure why you deleted your post… maybe you got it working… either way the warn light and RTC/timers are all works in progress Use them how you like
I deleted it because later on because re-reading your posts I found all the answers. At the time I didn’n know how deletion works, now I know.
Your project works for me, the thing I changed was to invert the gpio state to HIGH for open valve and LOW for closed valve
I would like to fork your git project and try to add features like timer, but I don’t have yet an idea of how I can manage the GPIO state (invert it) from project settings.
For now I will stick to your project, slightly modified and with an added eventor widget for planning next irrigation time.
For the future I would like to implement a google-calendar syncronized irrigation schedule and weather forecast related decisions. Also, the system should be able to operate by itself following the last (google calendar) syncronized schedule in case of Internet outage.
First, cool project Jamin
Im trying to implement the same setup but based on watering time and moisture threshold, as I only have one sensor and 6 valves or sprinkler zones.
Do you have a wiring diagram? as I am a newbie I need visual reinforcement to fully understand inputs and outputs
