I’m starting to think about a garden project ready for the summer. At the moment I have no hardware for the garden at all but I have experience with ESP8266/Arduino (currently using some for PIR/Temp Sensors in HASS).
If you were to start from scratch, what hardware would you use? At the moment I have an outside tap and a water butt and NOTHING else. Would be interested to hear what people would recommend.
What I’d like to do is… water my veg patch, borders and grass.
I’m using Dark Sky to predict weather in HASS today. And I have a weather station linked to Wunderground which is then imported into HASS for live weather of my garden also (temp, wind direction, speed and rain)
Working on same. Got a LinkNode R4 controlled by HA/MQTT but would like to see HA code for nice UI to set and run an irrigation schedule.
Did you finish your project?
Any chance of sharing on GitHub?
Hey revz
The code is all there in the postings. HASS has moved on a lot and things might not all work anymore but the basics still does. I have started to add and change things a bit since as well so I can’t realy share this any more as it was shown here.
If I had to do it again I would use python scripts, custom_ui and make a custom sprinkler component based on the switch component. That is the problem with HASS it is sooo flexible
Ah, yes ok I see that now. Good advice re: python scripts and custom UI, I’ve seen that approach recommended elsewhere. Agreed re: HASS- flexibility is its strength but can be a problem too!
It is a sensor that calculates th ethe next rundate based on the various settings on the valve

To be fair I don’t know if it is all still running (as there where a few HASS updates) as it is winter here and I haven’t been using it since September. I guess in a couple of months I need to get it up and running again.
Will not update and remains “Opened 0 minutes ago”.
Looking online this seems due to template sensor values not updating with now().
Fix: Link. Create a new Time & Date sensor then use that in place of “Now()”
I.E. Replace “now()” with “strptime(states.sensor.date__time.state, ‘%Y-%m-%d, %H:%M’”
Hey guys, had quite a struggle to get this working on 0.94.0. I’m experiencing issues when setting the schedule to include more than one day, for instance, Mon,Tue,Wednesday. The next runtime will change to “Not Set” Is this normal? The next runtime on any other static day like just “Monday” works without an issue.

My project uses only sonoff Flashed with Tasmota. In Hass have UI and one scene, some automation only for emergency stop and notifications to phone apk. Base is on Node-Red.
