Nice. I did something similar with an ESP32 and three separate relay modules recently ( I only have three zones). I just use the ESPhome API rather than MQTT. Have you got a screenshot of your control interface?
This is is what I’ve ended up with for now but am always on the lookout for improvements.
I’m waiting for the relatively new material design “sprinkler” icon to be available in HA to update those plant icons.
Nice project with excellent documentation!
Thanks for sharing!
Nice! Good spot!
haha I know… I am absolutely terrible at coming up with creative names.
Wow! Your setup looks incredible
I haven’t had a chance to deep dive into customizing the UI for my setup yet so I just have the basic switch entity card. I was thinking of doing something along the lines of Floorplan and including the yard zones within that.
Could you share your config for that beautiful display you have there?
As for the “sprinkler” icon, it is available in v0.98.1+

Awesome! What card modder are you using on your setup to style the cards? I remember coming across a couple, but for some reason my brain is broken right now and I can’t seem to work my Google magic.
This one:
Hi Tom,
I was so impressed with that interface I extended the automations into Node-red and made some slight adjustments to some of the templating. Dropping back here in case someone is grappling with this in the future. There are probably better more effective ways of doing this in NR as I am still learning.
My flow for a zone is below in case it is useful to anyone else:

I’ve just added a Miflora plant sensor. Currently stabbed into my lawn with a rubber glove finger over it for waterproofing.
I’m waiting for it to rain to get a baseline on the sensor to see if it’s worth including in the automations.
Hi Tom,
How goes you the Hobart MiFloras? With a good dose of rain over the last 48 hours here I got to tinkering with the scheduler logic and decided to use the recorded history from the sensor.bom_brisbane_rain_today and use it as a threshold test to determine if the schedule should start.
You can see the sensor resetting each morning at 9am (as designed) but so I’ve searched for the maximum number in that sensor when the sprinklers are due to start.
I’ve picked 48 hours and 30mm of rain in that time as a logic check. I’ve plucked those numbers from thin air as that is the current rainfall we’ve received here (see below). When these are due to kick off I’ll go out and do a quick soil moisture test (using my digits) to see if it needs adjusting. Anyway, I’ve updated my yaml/node-red to include this new logic, again in case anyone comes along later and finds it useful.
We’ve had very little rain here. I live in the rain shadow of a mountain. Just enough to keep the moisture level around 25% to 30%. I notice that the Lux sensor has stopped working. No big deal as I wasn’t using it. Also the temperature readings are all over the place due to the sensor being in it’s own little greenhouse.
I’m still not convinced it’s going to be any use.
My AM sprinkler run starts at 8am so I can use the rainfall to 9am sensor without having to store it.
I’ve been watching the ground and anything over 0.5mm in 24 hours seems to soak the top level. My soil is very sandy though so it drains away quickly.
I updated my time remaining sensors so that they only show a value if the sprinkler valve is on:
- platform: template
sensors:
zone_1_time_remaining:
friendly_name: 'Time Remaining'
entity_id:
- input_number.zone_1_time_remaining
- sensor.time
- switch.zone_1
value_template: >
{% if is_state('switch.zone_1', 'on') %}
{{ [ (states('input_number.zone_1_run_time')|int - (as_timestamp(now()) - as_timestamp(states.switch.zone_1.last_changed))/60)|round(0) ,0 ] | max }}
{% else %}
0
{% endif %}
unit_of_measurement: "min"
Otherwise restarts and switching off the zone valve trigger it to start counting down.
Nice. That was one of the adjustments I made as well as restarts were messing with it.
I got some moisture data from a 15 minute sprinkler run this morning:
Need more data before I decide what to do with it.
Definitely and not just point in time either as historical moisture over time is the key. It drops away quite quickly and back to your normal 25%. You’re not joking about it draining quickly. 
This makes me want to buy everything to this happen. Beautiful!
Does the opto isolated 5vdc relay module run fine if the IO input voltage is 3.3 vdc? Supply voltage 5vdc.
I have few relay modules with transistors and those does not run fine with 3.3 vdc. Have to have other transistor to drive 5vdc to relay from esp 3.3vdc pins.
