Dear @Mahko_Mahko
Very nice post.
I was just testing you ESP Code. It is very nice!!!
I was wondering why you are using “input_boolean.defeat_sleep” with a helper and not a dedicated switch for this device?
Did you tried such a solution?
Regards
Adrian
Thanks!
I’ve refined the config more which I’ll repost soonish.
I was considering having both wake options.
The remote virtual switch doesn’t require any hardware.
A button/switch would need to be weatherproofed.
I may still add one.
I recall that a wake button is better than a wake switch. Something about it being hard to determine the true state of a switch on boot. Might be wrong though.
You’re welcome.
I was more thinking about a “remote” virtual switch on the device, and not created with a helper.
There where i have my switch Test.
Oh right I see.
The virtual switch can’t be on the device as when it is in deep sleep it will not track the state as changed in HA / retrieve the changed state when it wakes (I think).
I would prefer that but it doesn’t seem to work as you might want. Let me know if you find otherwise.
Till now, i couldn’t fine a solution.
Maybe someone else?
I will open a new Topic with this question.

Underneath it’s just like this (it’s not the same as below but it is just a stump below soil)…! Hope it survives!

Interesting project. I just started something simular for my balcony. No plumbing and no power outlet.
I ordered some parts from Aliexpress. As for now it is enough for 8 plants, expandable to 16. I use a 8-relay board with onboard ESP, with an extra 8-relay board I can expand it to 16.
Each plant has it’s own micropump. The idea is to measure the moisture and when it’s on the minimum the according pump starts for a defined time to water it to the max level. I want to do that with some interruptions to get a more accurate measuring of the moisture level. The main hose comes from the tank, goes tot an 8-fold divider. From there there goes a hose to every pump.
I just received all the parts and programmed the ESP so it is visible in Home Assistant, so I’m not that far yet

Keep me posted on your project please.
I’m probably going to do another one when I finally finish this one that will service two plants, so keen to see your “multi plant solution”.
The new one will replace my old “beer dispenser” irrigation system;)
That’s a really nice way to do it with a beer pump 
What type of sensor are you using for the waterlevel sensor in the tank?
The new system has a VL53L0X. I’m still working through some reliability issues. Might be connections. Stops reporting when battery voltage gets lower. But generally works well. Much smaller than an ultrasonic.
The old system doesn’t have anything. I got a float switch which I was going to use with an aqara reed switch but I never got around to installing it.
I think I was originally going to pop one of these in the bottom but the signal range didn’t seem to be good and I don’t think they’re really supposed to be immersed.

I’m not at that point yet, but I have to add one in my system as well. I’ll have a look at that one when I’m going to add one.

Rewired it with better quality wire and it seems to be ok now.
Thanks, I’ll keep that in mind
Can you share your button code from ha?
Which button do you mean?
I thought you were trying to add a button to the dashboard to stop deepsleep? I’m trying to figure out how to prevent my sensor node from going to sleep too do OTA updates when needed.

yeah my main way is based on this approach. You toggle on a HA control and next time it wakes and connects, it will stay awake.
The HA config is similar to this (think I’ve changed the name).

I’ll maintain my master config here. May not maintain it well though.

This post is for content relating to it’s operation.
I’ll start with a high level description. It essentially works very similar to other irrigation and deep sleep projects projects around:
- Wake up from deep sleep periodically and see if the plant needs water. If so, water, if not, back to sleep.
- Don’t water the plant if battery is low, instead, go back to sleep for a long time and hope you get recharged on next wake.
- Don’t water the plant if the tank level is low.
- The watering regime might be described as “incremental drip-feed towards an upper target, followed by drying towards a lower threshold”. This lets the plant dry out a bit, then “gives it a good water, but slowly rather than all at once”… I still need to monitor that this is working ok.
- The light sensor is handy for checking how much light both the plant and the solar panel is getting.
