ESPHome Irrigation

ESPHome
1

During a recent update, I discovered a new component for ESPHome; Irrigation. Given that I had recently started working on an irrigation system, I was pleased to see this addition.

I have a couple of ESP8266’s already running on HA. A salt level detector and a garage door switch. I’d like to add the irrigation system. Based on my understanding of the irrigation integration, I’ve pieced together some code. It’s meant for a four valve control. No pump, just four valves. Would you mind having a look through it and advising of any issues?

For starters an ESP01 does not have all those GPIO’s you plan to use. You need to change the board: listing.

Secondly, I suggest checking here to see which GPIO’s you can / can’t use.

Also, this will work for a starting point but you might want to add in a way to change the run times from HA. There is an example on the ESPhome Sprinkler component doc page of how to use the ‘multiplier’.

Didn’t realize that, thanks for pointing that out.

Thanks for the link.

For sure! I thought something was missing. Reading the documents over again, it seems there may be more than that to add.

Thanks

I currently have an ESP running my sprinklers (and bore pump) which uses ESPhome and has been great for years but since this new Component I’m now wanting to re-code it since it’s currently dependant on HA doing the automation. This component looks like a great addition to ESPhome.

I’m rather new to ESPHome. A little challenged when it comes to programming yaml but I’m slowly learning. I have three other ESP devices programmed and running successfully. I’m looking forward to working my way through this project.
