Initially I had tried to run code from the project here but after expanding it out to the 8 zones I needed I ran into trouble. It ran the ESPhome out of resources (stack overflow issues) and also would not compile with ESPhome running on my Home Assistant Rpi4. I had to compile using ESPhome via Python on my desktop Windows 10 machine each time I wanted to work on the code. This was quite a discouragement as it was awkward to use (and setup) so I was happy when ESPhome added a native sprinkler component now.
The top blocks of #commented out code above reflects some of the things I had to add to get it to compile because of the resource issues, and gives context to why I have moved to the native sprinkler component.
Things missing currently are:
Code to use the buttons
Internal or external schedules (easy fix if using HA frontend).
Code to display the actual running zones run time and remaining time on the LCD
Hi bremby.
I don’t have any schematic as I just build up as I go. The connections are this:
The four buttons share one common ground, and each button goes to an input on ‘IN5 - IN8’.
The 16x2 LCD has a I2C converter attached like found on AliExpress or Ebay.
https://www.aliexpress.com/item/32713904220.html?
It connects to the header designated ‘IIC’ but has ground connected to the spare ground pin on header ‘P2’.
Board power comes from the 24V AC irrigation transformer (black wires seen in the bottom of build image), the transformer is also connected to each relay by ‘daisy chained’ wire links as seen in the image.
The 24V AC is converted to 12V DC for the KC868 board. To do that I used a small 2 Amp bridge rectifier that in turn feeds a 36V DC to 12V DC converter module (which sits at the top behind the LCD). Both are soldered to small Vero board (AKA perf board) strip to make it easy to mount to the box.
My DC-DC module is obsolete, but any module with greater than 36V DC input and at least 12V DC output at 2A or more will be fine…
The 12V DC output is wired direct to the KC868 +12V power input.
Output for the 8x irrigation valves is via the Normally Open contact of each zone relay (not yet connected). Each relay Common contact is connected to one side of the 24V AC transformer via the row of tinned wire links.
This is my code currently below. I’ve added ability to change the LCD display to follow the status of the running zone. I don’t have any internal scheduling yet, and I’m not sure I need too, maybe a default program if HA is off-air and one button assigned to start a manual watering.
Not sure yet if I should use HA automations for scheduling or create of borrow something for Node-Red…

I have something to fix/understand:
- when I disable a zone, if I use the Next or Previous button the zone isn’t skipped. It works if I toggle the switch. any idea where is my error?
- I would like to have to total amout cycle remaing time and if i’m running more cycles what is the actual cycle eg 2/3, 3/6, etc
- can be possible to pass the zone value with
sprinkler.start_single_valvedirectly by the UI with a drop down list menu? eg. press the single button and then select which valve to control - how to use/interact with the queue (add/remove, see the queue list, etc)
I found a response for point 1
- The
next_valve,previous_valveandstart_single_valveactions ignore whether a valve is enabled via its enable switch.
Not sure I can help with points 2, 3, 4 as your Yaml skills are well above mine. Nice frontend cards by the way 
I found an issue with ‘resume’ myself but have not tried to fault find it. I can Pause via GUI but Resume does not work.
Yes it would be better if previous/next did check the valve enable state. Perhaps this should be raised in the ESPhome Sprinkler git issues.
For my build I probably won’t use any Repeat cycle function, as I think the Multiplier is the way I’d change a cycle.
I’m experimenting a little bit with the “challenge” n#2

Cool. Nothing quite so interesting here. Installed the four physical buttons on the box lid and configured ESPhome to read them. Working fine. Now to do something useful with them.
(also adding a power input fuse to the box from the 24V AC transformer)

thank you @mr.sneezy , as you are some “steps” ahead me… shall you share how you wired the buttons and how configured the inputs?
I will try my best to get to the same page:D
I added four buttons using normally open momentary switches I had in my parts box. Kinconys diagram shows how to wire them. I picked I2C I/O hub inputs 5-8 because they were close to the ground pin which needs to be connected to one side of each button. You could use 1-4 etc to be more logical.
Here is a closer image of the wiring as seen on the circuit board showing the 5 wires to the I2C I/O hub inputs.
Here’s a image of the back of the buttons in case it helps, really nothing to see though.
I’ve added a small inline fuse and holder to the main 24V AC input, as the transformer has none. It’s to protect the transformer if a valve cable in the garden is damged (shorted).
Like the LCD mount and the button mount, it’s 3D printed on my old but reliable Prusa i3 clone.
Code associated with the buttons for testing them. Results are seen in the ESPhome logs live view after flashing if you don’t have the LCD…

Now that the buttons do useful stuff, I need to show that on the LCD (i.e paused status).
The paused valve number apparently is available internally form what I see on Github references, but I will need to make my LCD cases more complex or rethink that method…
paused_valve()
This is awesome! I just finished a basic irrigation controller 4 or 5 months before they introduced the sprinkler component but, doing it over had been on my to do list. Reading through the docs, I’ve been excitedl to take on this challenge and thanks to your awesome post I’ll have something to look st for help. Thank you for taking your time and sharing this with us! I appreciate this very much!
@mr.sneezy , I did something to simplify (I guess) the code for the SWITCH portion; this should safe a lot of rows…, let me know what do you think
lambda: |-
switch (id(esp32_sprinkler_ctrlr).active_valve().value_or(-1)) {
case -1:
it.strftime(0, 0, "%a", id(homeassistant_time).now());
it.strftime(10, 0, "%d-%m-%Y", id(homeassistant_time).now());
it.strftime(12, 1,"%H:%M:%S", id(homeassistant_time).now());
it.printf(0, 3, "Status: %s", id(esp32_sprinkler_ctrlr_status).state.c_str());
if (id(esp32_sprinkler_ctrlr_status).state == "Paused") {
it.printf(0, 2, "Zone %s", id(zone_active_sensor).state.c_str());
it.printf(10, 2, "T: %s", id(zone_time_remaining_sensor).state.c_str());
}
break;
default:
it.printf(0, 0, "Zone %s:", id(zone_active_sensor).state.c_str());
it.printf(8, 0, "%s", id(zone_active_sensor).state.c_str() ? "ON" : "OFF");
it.printf(0, 1, "Time Letf: %s", id(zone_time_remaining_sensor).state.c_str());
break;
}
I also made the LCD “dimmable” following these instructions from @LUNZ 
[Dimmable PCF8574 LCD Display with ESPHome]
(Dimmable PCF8574 LCD Display with ESPHome)
here is the full code, just in case

@mr.sneezy Very nice implementation of your ESPHome based irrigation system. I have an old RainMachine that is about to die and their replacement is both expensive and old so I think I will build my own. One thing I was curious about your setup is how the time is tracked as I did not see any reference to an RTC on the board. Did you add one? Or is time completely dependent on HA which may be an issue in case the system needs to operate on its own for some time.
I didn’t worry about RTC until it proves necessary yet. So far the network time has been reliable so the watering has been reliable.
Oddly enough I did another recent small project for somebody else that uses a $5 RTC module on an ESP32. I used this one below, but it needed four pull up resistors removed to make the SDA and SCL lines 3.3V compatible. As this module is I2C driven it should be not hard to add to the 8ch relay board in parallel with the LCD if I need too.

Hi,
Great work. I am looking for a solution where the controller can connect to Home Assistant via ie. ethernet. I see this board has ethernet connector. Could this be connected to Home Assistant with ethernet or the eth. connector is for other purposes?
I believe so yes. ESPhome supports a good number of Ethernet chips and the one on this board is the first one they mention in the ESPhome list.
I have used Ethernet with ESPhome fine on other boards, just not this one yet.
