[Question] HAsmartirrigation Integration about irrigation_unlimited

[rgc99]

Glad this project is working out for you. Once you have things up and running there are a number of service calls available. One of these service calls allows you to adjust the watering times you have setup in the yaml file.
HAsmartirrigation provides a number of sensors with the hourly or daily adjusted run times. You need to create an automation that takes the data from the HAsmartirrigation sensor and makes a service call to irrigation_unlimited.adjust_time.
Personally I have not used this integration and instead use observation data provided by my personal weather station to adjust watering times based on rainfall and temperature. Details can be found in the documentation. There are many thoughts and ideas along with numerous weather services giving a lot of scope for creating adjustments.

Thanks for getting back to me about this. I have no clue how to work with it, since all of my automation so far was done with Node-Red. Also I do not own a weather station since I have not found one yet, which suits my needs and is available on the German market (if you happen to know any, let me know as I would be glad to set something up on the roof).
I think the beauty of the HAsmartirrigation is the fact that they calculate a value out of evaporation, area to cover and how much water the individual sprinklers need. So this is highly custom and even with my own weather station I would still love to have this data integrated.
So could you provide an example how to work with HAsmartirrigation and how it would be set up to adjust time. I only started looking a bit more under the surface and I'm not that much of a programmer so I have my difficulties adjusting your examples to what I want to archive. Any hint or idea would be highly appreciated.

Thank you very much! 😃

Not sure they sell my model of weather station any more but this is very much like it. https://www.ebay.com.au/itm/262073907445. The main thing is it sends the information to weather underground and there is a HA integration https://github.com/cytech/Home-Assistant-wundergroundpws that will pull the data back into HA.

This automation runs at 04:00 and takes the calculated run time from HAsmartirrigation and updates Irrigation Unlimited with the new watering time. It then calls HAsmartirrigation to reset the bucket.

Hopefully this will point you in the right direction.

It definitely does, thanks a lot for your help. This brings me a huge step forward to automatically have things running! 😃

Example now included in documentation.

There is one question remaining for me.
If I set the watering times based on the data from HAsmartirrigation, what kind of schedule should I configure?
I want to check daily if there is a manual watering time set, if so: start irrigation. If not: do nothing. Is this possible? Or did I miss it in the documentation?

[rgc99]

Create a schedule for when you would like to water. For a lot of people this is before dawn but there are many reasons such as local regulations, water pressure, convenience, there are many opinions on this. The duration won't really matter as HAsmartirrigation will override this value so just set it to something sensible. The automation script takes the calculated run time from HAsmartirrigation and transfers it to Irrigation Unlimited via a service call. If the calculated value is 0 then the irrigation won't run.

[rmeekers]

ah wonderful. I didn't understand how it would respond if there was no override. But if it's set to zero, then it won't run.

Thanks for your great work!
