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)

It's not tested because i didn't finish the hardware yet ,but should be pretty close from what i want ..and clean..

And theres more.... i asked for he..she..it.. explain me the behavior of the code and this is what it explain:

🎯 Purpose of the Code
This Arduino sketch reads analog values from 16 linear Hall effect sensors (49E) connected via a CD74HC4067 16-channel analog multiplexer to measure the position of a floating magnet (e.g., on water). It calculates the water level as a percentage (0% = bottom, 100% = top) and detects the direction of change (rising or falling water level). The data is then sent via MySensors to a gateway/controller.

🔌 Hardware Involved
16 Hall Effect Sensors (49E) arranged vertically to detect a magnet's position.

CD74HC4067 multiplexer to connect all 16 sensors to a single analog pin (A0).

MySensors library for wireless communication (e.g., with an MQTT or home automation gateway).

⚙️ Main Code Behavior
1. Initialization
before(): Configures the multiplexer select lines S0 to S3 as outputs.

presentation(): Sends node and sensor info to the MySensors controller.

setup(): Empty in this version (can be used for future initialization).

2. Main Loop (loop())
Runs every 5 seconds (readInterval = 5000 ms):

a. Read Sensor Values
Iterates through all 16 channels of the multiplexer.

For each channel, selects the sensor via selectMuxChannel(i) and reads its analog value from pin A0.

Stores all values in the readings[] array.

b. Find Position of the Magnet
Finds the pair of consecutive sensors with the highest combined reading (indicating proximity of the magnet).

Uses those two sensors to calculate a more accurate interpolated position (sensorPosition), including fractional values.

c. Convert to Water Level Percentage
Translates the sensor position to a percentage level, with 100% at the top sensor and 0% at the bottom.

Uses:

cpp
Copiar
Editar
float levelPercent = (1.0 - sensorPosition / (TOTAL_SENSORS - 1)) * 100.0;
d. Hysteresis Filtering
Uses a confirmation counter to avoid sending data for small noise fluctuations.

Only reports new data if the level has changed significantly (by more than 0.5%) and remains stable for 3 readings.

e. Send Data (if changed significantly)
Sends the level as a float with 1 decimal point.

Sends the direction:

1 for rising water level

0 for falling water level

Prints this info to the serial monitor as debug output.

🧠 Smart Features in the Code
Interpolation: Instead of picking a single sensor, it uses interpolation between the two strongest sensors to increase resolution.

Noise Filtering: Uses hysteresis and confirmation logic to avoid spamming updates due to noise.

Direction Detection: Reports whether the water is rising or falling.

📤 Output (via MySensors & Serial)
V_LEVEL message: Water level percentage (e.g., 72.5%)

V_STATUS message: Direction (1 = up/rising, 0 = down/falling)

Serial example output:

mathematica
Copiar
Editar
Level (%): 72.5 - Direction: RISING
🧪 Use Cases
Smart water tank monitoring

Sump pit level monitoring

Reservoir or hydroponics water level sensing

Any linear position tracking using a magnet + Hall sensors

Let me know if you’d like a diagram or simulation example of how this works!

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

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...

i believe this problem has to be with rfm69CW and not the rfm69W . i have boot versions 868mhz and normally always the CW cause me this issues if is not batery powered even with 100uf +100nf caps filtering on transformer out, caps on the rfm60 power etc... maybe they are fake or have any problem. . i just ordered new rfm69W board and let me see if get better. right now i have like 10 nodes running outdoor on irrigation ,controlling relays and lights ,and metering temperatures. all with RFM69W ans HW ,this CW always give problems...

Hello . it's the 3rd node that i build with the combo arduino promini 3.3v + hlk-pm01 + rfm69 and all need wire ground to earth (on wallsocket) to let rfm69 comunicate.
otherwise will fail on every comunication even near Gateway...
Personally i only think in noise.but everyone say that hlk-pm01 are low noise.
I'm not using any cap after hlk-pm01 for snooth voltage but i already try it before without better result.
rfm69 is powered by the pro mini integrated regulator.
Any one had this problem?

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

this is my gw . in fact i never understud very well the child thing. last one is "tanque"( tank) is ths node that we talk and is showing as 13 ?? why?

normally what i do is go to devices ,see what next id is available and atribute it to children..worked until now but i think its wrong

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 .
