Hello everybody.
Since i discover this awesome project open source (mysensors) and the awesome work done here, i have been converted all my arduinos to Mysensor library ,because i already had Vera lite managing my home.

so lets share what i already did. **Pictures!!!! **

First, my gateway:
i used a round small box , a ftdi adapter,and a 5v promini with 3.3v regulator on nrf24 .
On picture is a normal nrf24 but then i use a amplified version that have an coaxial cable connected and an 2.4ghz antenna on outside roof(attach to my external TV antenna) ,So i can receive and send information to all my incoming sensors ,in all my garden(+3500m2) and it can receive inside home signal aswell.

And then ,on 3rd day ,I created an irrigation control......

Its not tested on vera yet, but at first look i have some work to do before it work properly. And i need replace this power wires for 12vpower adapter ones.

Look at the switch ... you cant see it ... but its inside top rubber. just press on rubber and its water proof

Sory about my English errors ,not my natural language:P

Do you think you've seen all kinds of projects here? So ..think again.
There it is my chicken eggs encubator .
Made from a 25 liters plastic storage box and some foam outside to prevent heat loss.
i used 2 X 18w halogen g9 bulbs and a 230v dimmer to decrease light brightness.

There is a diagram above from fritzing. I uses an main arduino that controls a SSR relay for controls halogen light bulbs. this light bulbs are dimmed to half(in my case)
for hold temperature much time as possible without decrease temperature.That makes SSR stay on for some minutes before goes off again. if halogen light are to powerfull makes the SSR goes on and off many times in short period. the ideal situation is having the dimmer controlled by arduino and hold temperature without turn ligh off ,but i didn't got this dimmer yet(is there any one ready for try it? ).

this is the 3rd version i build and all the other version hatch almost all eggs(+/-80%) even with some issues on controlling temperature.i only had 1 fan and that caused some zones that overheated (more on coners).
Now i have 2x120mm(0.10A) pc fans that can spread hot air the same way in all this box.

Then i have a secondary arduino that it's for safe features. it controls an alarm buzzer(pc speaker) ,its connected to an temperature sensor (ds18b20) and send temperature to emoncms.com through an nrf24 wireless board
If temperatures goes over 39ºC or below 30ºC it sound an noisy alarm.Just in case main arduino or DHT22 fail.

Egg roller its made os aluminium and plastic egg racks cutted and glued with hot glue(screws were better but this is enought to hold eggs).it makes 45º each side.
An High torque servo roll every 60 minutes. Note that an regular servo does not have enough torque should be an high toque version.

eggs ready to start hatching! note the ds18b20 sensor in the back of the DHT22 sensor.they will stay same height than egg rack.

2x18w halogen lighs

lcd screen is configured for simplicity . code have hours and days passed and remaining ,but i decide use just passed days, temperature manual offset and time for next egg roll(minutes),and of course temperature and humidity on first line.

its a mess of cables ...i know. It's what happening when we always improve our project until it be a final version
I used usb cables from computer cases for wire sensors, it work really well .
There's 2 solid state relays on picture but we only need one.

Parts:
2x 12v 120mm pc fan(0.10A -slow speed/low noise)
1x LM2596
1x High torque servo or step motor(need additional controller).
1x 5v Arduino pro mini (or equivalent )
1x DHT22
1x 5v relay Or SSR G3MB-202P Solid State
1x 2 lines I2C 1602 LCD (i2c ,not serial) or 4 lines if you what more info on screen like time left and time spent clock.
2x monetary switch
2x 10k resistors
2x 18w halogen light bulbs
2x G9 Ceramic Sockets
1x AC 220V 2000W SCR Voltage Regulator (overkill for 36W i know, but it cost 1.50€ on ebay)

Optional parts
1x 3.3v pro mini (or equivalent)
1x computer speaker(buzzer)
1x DS18b20
1x NRF24L01
1x 4.7K Resistor
1x 3.7v litio battery (cellphone or 18650 cell)
1x Battery Protection Board(just for charge battery before start hatching)
note: this battery just hold main arduino in case of power failure. During normal work it never charge or discharge due 5v on line from LM2526

NOTE: English it's not my language. i'm sorry some errors that can happens

hello. like o wrote before my veralite dies after 4 years of work.
So now i'm on Domoticz.For the dead vera lite i recover the z-wave part. i had some doubts that it works but i have seen n razberry cards that the hardware its the same,so why not try.
I just cutted the 4 layers pcb and solder 4 wires on zm3102 chip directly(tx,rc,vcc and gnd). some hot glue and some nail polish /or epoxy to seal cutted sides.There are no working leds but how cares. and yea.I have an external antena . Everything fits inside vera case aswell(recycling on the best),raspbery,zwave card and mysensors GW.
in beginning domoticz didn't detect it like in official zwave cards ,there are some procedures to make before,but soon as setup button gets blue ,was just reset or exclude and then include nodes again on Domoticz. until now (24hours later) everything still work like a charm ,And let me say Domoticz is far more complete than mios os.

Hello guys.
Years after MySensors release , and we still here talking here about, on on my electronic engineer opinion ,the best/usefull open source library ever!!! i say that because all my outdoor appliances, work with this stable library . Water heating solar panels, irrigation systems , outdoor light , main gate and basement gate can report status and command, water level from the irrigation system etc etc. Even for save water because i have timeouts and safe features for not water water or forget plants watering.... i only don't use the inside because my hardware don't fit inside concrete wall boxes....
Now since i had to debug one of my sensors and realize the power of chatgpt now i just got lazy and don't program my sensors myself. I just explain what i want and the AI do it.
have you tried it? Amazing .
This morning i did a water level sensor to replace my sonar one. Asked one mysensors code for 16 hall effect sensors connected to a mux cd74hc4067 and it suggest ; why no use interpolation,why not use sensor
hysteresis? hyster... what? i didn't its called like that. want cms or percentage....- DO it!! . 10 minutes later i had a hell of compacted code that do what i want WITHOUT BUGS and compile errors!!! yes,it's amazing because i'm not programmer and i can program c++ on arduino code but not much more than this....
So don't stop your creativity because you are not very good programmer and you don't even know how to start you project. mysensors library it's well known from AI . .thank you my sensors team

if it is an emergency button should be connected directly to relay (connected by hardware). And not using code,because if arduino it's freezed it will not respond and you cant stop it

@zboblamont said in #define DEFAULT_RFM69_IRQ_PIN:

So long as these are set before including the MySensors library it should indeed override the defaults.

OMG. this is the problem! i was defining AFTER Including Mysensors library. well i should knew that if i know more about programing

this code now is working comunicating well.

I still having an issue. termometer doesn't appear on domoticz. i think it's well presented... i'm not sure whats happen. but the axel for angle, that i need is , working good already .

The corret statement is .

And that is the result . 14 chicks of 25eggs ,but i could say that was 100% sucess because the other eggs were not fertilized. not even a single dead before or after hatch. Its not the arduino the most versatile machine?

top left chic just born 10min before i take the picture:P

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.

thank you for reply @mfalkvidd
Payload like 100 shoud be 100% on domoticz, right? how does domoticz "know" that a blindcover /or shutter is open or close? because it's not respondig to that...

because wifi is not the most safe for humans... sleeping etc

what are you talking about???
are you the ones that say wifi boils water on a cup?

mysensors library works on nrf24l01+ modules, Not wifi. its a kind of Bluetooth already... anyway Bluetooth is 2.4ghz like wi-fi, but Bluetooth consumes less power (Theoricly)

i'm bilding this right now: http://www.qsl.net/eb4eqa/bt_yagi/bt_yagi.htm
i tell you what is the increment of range in the next weekend ...

i have one of temp sensors under a water solar panel and the aluminium from the frame get me crazy because that sensor lose many of the sent reads to gw. i will finish that yagi antenna and solder that to my nrf24 and i hope signal increase performance.

in my house (i dont have neighboard les than 80m with wifi signal and noise from other routers or any king of 2.4ghz signals ) i can send a door sensor signal(from my entrance gate) by 50m and 1 wall . that one have this antena alredy on tx:
http://martybugs.net/wireless/collinear.cgi

hi guys . I just discovered how some main zwave brands power their modules.
the chip used its LNK302DN and the sckematic its(adapted for 5v or 3.3v):

SEE PAGE 4 AND 5
http://www.farnell.com/datasheets/2059771.pdf?_ga=2.242203521.2016163251.1496347222-1734612754.1489089187

That's something!

what about buid an dimmer sensor ,put it directly to the fan motor and forget that remote? that is what i would do. that its all about create a scene for that fan, temperature limits,motion .... smat fan you know

what is the motor power ?

@mfalkvidd said in Crazy timer on my sketch:

the debug log will probably give good insight to why the node reacts early.

i just discovered the auto-formatting right now

About debug (mydebug) just reacts as normal,everything as should, but in shorter time... less 70-80% of the time most the times. Tomorrow i will get the arduino that its watering right know and change the code a bit..try some "while" instead of "if" or hammering it

Maybe you are right and it's the proximity to a switching tranformer like this hlk-pm01 .They are all on same protoboard aprox 50x60mm. i could build a sheld on it but....now its working with the rfm69version W ok for a few days.
The strange part is this combo was very used a few years now on made pcbs the on forum wher they had the maker/developer contest and never seen a line of this problem...

Description
This project born from a necessity of water my domestic vegetable garden. Lettuces needs water all day and many times I forgot or don’t have time. There are other projects for irrigation but I have special requirements, it’s just one valve and valves that are sold in my country are AC24V for commercial controllers.
So I build a controller to add to my existing Mysensors/Domoticz network that can handle an AC24V with 12V to 3V volt DC . +/-3 Volts it’s how power this AC24V volts solenoids because AC24V transformers are difficult to find and expensive for what they are(ferromagnetic). And once solenoids(coils) warms up a lot especially with DC,with 3 volt they run cold and its the minimum that my valve requires to stay open.

How it works?
Watering can be set on Arduino, 2 times per day ,morning and at evening. Or even once per day.
Or can be added timers on gateway (my case Domoticz) and everything stays remotely. Personally I prefer have it hard coded on Arduino in case of transmission fail.
I add a switch (one per valve) to turn it on every time I want and it automatically shuts down on timer that it’s set on code ,in “VALVE_TIME”. 1 hour by default.
So there this timeout work in any of the timers(switch,gateway or internal timer).

On code ,I set to “225”(100% or DC12v) on mosfet (IRLZ44N) during 400ms to kick the solenoid to open and then is set to “90” the rest of time to have around 3V on valve terminals. The entire project it’s powered with a standard electronic DC12V/2A transformer that powers the Arduino and the water valve.

There are 2 leds. One "Valve Power On" and other is TX/RX,note that blink time was slowed down for better understand when is communicating or its just retrying in loop and can't reach the gateway (for example). I have really good result with RFM69H(868mhz) communications. My garden its 40m/50m of my house or GW an never realize that were lost communications.

What I used:
Arduino (any 328P), I used pro mini 3.3v because the RFM69
RFM69H
LM2596 Voltage step down 12v→3.3V (or equivalent)
IRLZ44N or any logic level mosfet that work on 3.3V(one per valve that you use)
x2 leds
x2 screw terminal (2 wires)
Push Switch (Normally open)
Resistors x2 - 10K and x2 – 220ohm
Protoboard (that green ones from ebay are awesome)
wire…

Some thoughts : On my prototypes, I rarely make a dedicated pcb, I use thin ,wire to bridge components on protoboards. They are easy to build and easy to repair or remake in case of some issue. Never had an unexpected shot-circuit. And when my board are outdoor ,I use nail polish or transparent spray paint to cover the entire board. that makes an water prof board. And believe me even ip67 outdoor cases sometimes let water get in.
This is an example of wiring , of course in this our project we have many less wires :example

Schematic

Note: each extra valve(Zone) needs an extra led, switch and mosfet.

Don’t let your garden dry!

pretty difficult question hum? lol

i solve it by forgetting TimeAlarms.h and set just an hour that triggers the solenoid like this
(HX and MH its the time,[hours] and [minutes] defined at beginning and its set manually)

 if (hour() == HX && minute() == MX )
    {

Nice catch! i didn´t see that . thank you

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

@mfalkvidd that was the problem! I correct the code and timers are working perfect now. I will post the skematic and code this night on projects for if someone want to use it . Very handy on summer for water some vegetables like i do. It's a very simple build.

I think i touch the rigth spot! WIFI ~
but my initial post was more about if they are reliable than if they are safe...
even a wood door it's not safe...an kick and you are in ... i don't believe someone will start robbing my house ,by entering in the shutter iot module by an wifi hack and open the shutter,brake doble glass windows and enter....
It's more a question if they are pratical and reliable? tey cost less than half of an zwave module..big point here...
and my main concern is ,are they all day comunicating with router or they usualy sleep? i'm not sure how wi-fi devices like esp8266 work. If they ping the router regularly or what?

my Domoticz its running on a PNY SD card for more than 2 years and didn't die yet. But i almost don't have power cuts . Any case i have another sandisk ultra sd with an clone from the running SD ready to replace this in case of fail.
You can buy and replace an raspberry by an fast and more expensive device...but this sd cards cost 3.75€ !!! power consumption of 1.5w- 1.9w in idle... what else can i want from my domotic system!

edit: i have 4 or 5 sensors transmitting and writing every 15min, so sd write, it's not too heavy,standart usage.

i use the simplest boxes that you find,that suface mount with 4 screws and ruber on door.
But be carefull with wall mount screws. if you drill the back of the box ,water come in beind this box. so this ones,the scrfew holes are outside the encosure an box is sealed...
another tip is drill on bottom for pass cables but put some neutral silicone. hot glue let water come in with time because expansion coeficient is diferent that the plastic box and open gaps

@zboblamont said in #define DEFAULT_RFM69_IRQ_PIN:

ode sketch to print locally over serial t

this is local log already. thal last line: 11233 TSF:MSG:SEND,4-4-0-0,s=99,c=1,t=0,pt=7,l=5,sg=0,ft=0,st=OK:36.5
is the message sending 36.5 degrees to gateway.

domoticz log report message received from this node...but is not even on devices...

Now is working. so what i did is call to children 0 and 1 and #define MY_NODE_ID 101 ,so next node appear on harware/mysensors gw ,and apear on devices as IDX 99 and 100... The auto node idx from domoticz shoud have caused some issue.... now is working
