Question and some spelling mistakes #18

Closed Phibins closed 4 years ago

Phibins commented 4 years ago

First off, this is really cool! Thanks for taking the time to share your code and write a very clear wiki!

Question: I see you used the

Sonoff 4 ch pro to switch on/off the taps

But how does a relay turn the taps on/off... Im a bit new, but i understand the relays are just the on/off switch. They must be attached to some device that turns the tap on/off. If so, what is the device you use to turn the water on and off?

I know you linked to the Orbit Sprinkler but this doesnt seem like something electronic that can be controlled by a relay.

Unless i misunderstood?

A couple spelling mistakes:

several instances of typo: "liter=litter" (i edited the page)

typo: "use-case"="usec-case" (im new to github - i couldn't, or dont know how, to edit the wiki page)

Also i rotated the image for you (although it could be more clear) for item #3. https://i.imgur.com/1XJbmQa.png

Toda Raba!

P.S.

I know you must be busy, but pictures of your devices for out door irrigation would be a reallly cool addition to this page :)... you can just throw them in anywhere

@Phibins I had a working system that wasn't smart (it was programmed with specific duration and specific schedule) I have something similar to Orbit Sprinkler. I just replaced the computer with a Sonoff 4ch. It works like that, If there is no power to the sprinkler it will be closed. If you put 24vAC it will open the sprinkler. 

So I took the old power and connected it throw the Sonoff "cold" switch. HA control the on/off and Tasmota make sure it will be closed after timeout (loss of network)

I have this sprinkler

Thanks for the spelling correction

I want ot use your brilliant code for the watering shedule, but need to get it working with my garden hose unfortunatly.

So if I buy something like this will I be able to hack it together with your smart schedule?

How do you know the flow rate coming out of the tap when its on? Is that a constant I would need to add to the program?

I am planning to have a garden hose lead to 4-5 flower-beds with a small (low-flow) sprinkler spout like this image

So i imagine a lot less water comes out compared toyour system, can i adjust for this?

@Phibins my solution just automatically tune the duration of the irrigation, it does not change the scheduling. I came from a point that I had a manual irrigation system that worked and could be tuned for specific weather point. The problem was that I needed to tune it for specific hot days or specific times that it was raining, this is not needed anymore. You should consult with a gardener for the design, then you need to connect the sprinklers on/off switch to HA for automatic tunning.

On my garden it works like a charm for a year now, I don’t remember when I manually touched it

This is the irrigation computer that was replaced https://galconc.com/product/8000/ With a simple sonoff + HA
