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.
hello, I’m trying to build an automatic watering system based on slightly modified your code, unfortunately I keep getting the error “class esphome: :sprinkler : :Sprinkler:” has no member named “time_remaining”. Do you know what could be causing this?

```Anyone can share an automated schedule?
Do you do the automation built in the esphome yaml or do you build it via HA automations? I want it to be on the esphome so if the network is down it wont fail
Thanks
I use HA automations to trigger the schedules via a HA Calender. My understanding is the zone times are stored local to the controller in ESPH, I can trigger a schedule locally via a button if the network is down (or not). Not sure if schedule timing works after the network is down. Mostly the issue here would be power failure on the mains, and that means the controller power is down also.
I use a template sensor to measure the daily mean temperature as a condition to allow trigger of a second schedule that can occur inbetween the main schedule days.
Did you ever fixed the time.remaining issue? I am getting the same error and prevents me from running this.
The Sprinkler component was changed from time_remaining() to time_remaining_active_valve() to return the value of the zone remaining time.
Update all the instances of time_remaining in the yaml and it will compile, I think there are 9.

I’ve had some WiFi connecting issues for a few months, shown up using a Ping monitor in HA. Trying to resolve them currently, although the irrigation schedules seem to be running as normal.
One thing that has helped is increasing the I2C clock frequency (800kHz) and also increasing the display update time to 2s. It could well be that I have a board issues though, like 3.3V regulator etc. I don’t think I had any connection issues in the past in the logs so that’s why I think it could be the board rather than coding…
Hello, can you share yaml for this card and automation?
Just to give back, I have expanded the original version:
Schedule build in so the unit can run without HA (Daily morning / evening)
I use the KinCony KC868-A16 so added 8 more channels
Make the rain threshold show in dashboard

Thanks for the contribution. I’ll have to try it out here when I have time.
An update on my KC868-A8 watering station. Early last summer here I noted the wifi dropping out on HA at odd times of the day, sometimes for hours. During these times I could not start a watering cycle. After a lot of trial and error at board level I decided to replace the ESP32 module on the KC868 board. Got a Wroom ESP32 from AliExpress and replaced the module. Since then I’ve had no connection issues. Getting the module off was harder than expected because there is a thermal pad right in the middle underneath that can’t be seen.
I had to remove the top tin shield to get enough heat into the middle of the module to remove it without damaging the KC board.
Here are some screenshots of my version. you can see the schedule added but I also added a rain factor. With this I can adjust the sensitive of the minimal amount of rain before it stops the irrigation. Next to the mulitplier some real finetuning tools. I live in the tropics so it is usually too much or not enough rain and the irrigation keeps my garden alive.
