Nice work. I did someting like this but much simplified. Only one temperature sensor,one soil moisture that i never used , and a 24v AC controlled by 5v DC.
Do you know that this 24v valved(our european ones )work better with low voltage dc, because don't heat up, but need a start up kick from 9v or so and then decrease it to 5v and at that voltage they hold open position and don't get hot .
Domoticz have a timer for every day on summer,and on winter is off. Soil moisture will help in case of rain but i never finish the integration of this one. Next spring i have to finish this
Thank you for sharing your project.

I changed all my radios to rfm68 exactly because poor range.probably you are on middle of a 2.4ghz signal war. Take a look on your wifi neighborhood.probably there's a lot of 2.4 signal already ,masking you small nrf24 signal.... And then all ebay ones are fake... Just make a try with 2 rfm69w and you never touch an nrf24 again.

My advise if you want upgrade and improve your domotics in your house is what i done. Domoticz,serial gateway, rfm69h and rfm69hw instead of nrf24 that i used before and replace all cards. Nrf24 have many range problems for me and the the chinise clone that are unknown quality in each order.all diferents each time i order...

My bet will be the power supply as well. i had one HC-SR501 running from battery for a few months .False triggers? every time sun comes out from a cloud! for outdoor they are crap.

Just for you know about power supplies , last project that i build a k type thermometer(for high temperatures) on my fireplace, i feed it with a HLK-PM01 and while I didn't connect negative terminal to the fireplace steel chassis(ground) , it fluctuate a lot during readings, like 20c then 45c,25 etc.. not even with a capacitor.

HUM.. nice to advise us then ..and make sense because my windwos 10 have driver updates off(and main updates off aswell…
that explains why i don't have my fake ftdi driver broken on my win 10,because i never update nothing that works,,, grrrr , i hate that Windows update and run policy…

by the way ,rollback to previews drivers and lock them from update. how to do?

if that is not enough create a rule on outgoing firewall trafic that block Windows update service and sihclient.exe from runing.

Yes ,try in other computer to be sure. I already had one windows that ftdi driver was broken(i did it trying revive an almel 34u2) and another time an Windows update (Windows 7 i think) brick all my ebay red and fake ftdi. I had to unbrick them... Nowadays i think Microsoft already don't do that.

I don 't know if it helps but i tell you my story. I had all network using nrf24l01(7or8 nodes) and i had some lost data ,random,depend day time etc... So i change all radios to rfm69 and 69hw and never had a lost packet again. Happy end

Now i have an arduino pro mini 3.3v@ 8mhz connected to raspberry by serial (usb ftdi original) managed by domoticz. Rocksolid solution until now. Its there for months (6 maybe). One of the nodes its 50 m outside,on main gate. And same node controls lights,gate open,door bell and a fence perimeter alarm(fence cutted) .Never miss a notification.

This is my solution to not have issues with radios modules
.

Erik .if you dont have a gateway or mysensors implemented in your house yet,you should do someting simple.that schetch its crazy for a new start person.
Some relays that fire by time its enouf. Wifi part that you want provably its realy Wi-Fi,not mysensors conection that its an wireless protocol,(not wifi). We are deep in summer,its not time to make a new irrigation controller from 0 and tryit

Hi to @Greymarvel .Well i already seen this movie before. I bought diferent nrf24 nodes,amplifed ,not amplified,with or without capacitors. In fact i had worst redults with amp nodes. I just change to rfm69hw and w
. No more low power/high power...etc. now i got my 4000m2 terrain covered (around 80m long).
I didn't check max range but i never had lost a packet again. I was a very good increment on my network stability.
That fake nrf24 chips are crazy and unstable and yes,all ebay cheap nodes are fake second i know.

@rahokos download the file and change the extension from file to .fzz
for any reason it happens when i upload this file.
