that quite likely a good idea... as its outside i could even drop a solar panel on it... as in this situation with 1 read every second (give take) the node wont get a a chance to sleep at all as i would be sending back to the gateway constantly...

hi all
after advice on an electric fence sensor node for mysensors

so I have a small 5KV Electric fence energizer which sends pulses of 5KV down the line in 1-2 second pulses
I'm trying to work out how to monitor it..
Ideally id love it to be self powered, but I'm tipping that's out of the questions, as the capacitor requirement I think would be huge to stop overloading....

so my two options I thought of were either a voltage divider (Research shows this probably wont work)
or a hall effect current sensor, but I've never worked with one of these and am unsure of how this one should go.

I know my main issue is going to be protecting to Arduino from the raw voltage as it would fry it in seconds.

has anyone worked on a similar project or able to advise on a good place to start?

thanks to assistance of some of the people here i now have up and running a front gate controller for my double front gates (Solar powered)

now have a node that monitors the batteries, knows if the gate is open or closed and has a relay for activating the gate

Yeah I'm changing up the circuit die to inaccuracy...
Is a arduino nano 5v powered from usb.....

Is anyone able to confirm if the calculations in this image are correct? I would need to multiply the result by 6 to get accurate numbers

I'm just currently stuggling with acuracy on my current design and figure bringing the max reading down would help
It's a 24v battery with solar cut off of 28.4v so it will never go over 30 anyway

think i have figured it out

adjusted the math based on another page
Vin = (Pin * 5.0) / 1023;

removed the factor of 11 stuff and i think it wasn't necessary?

@mfalkvidd you are correct you can do double and it works

now compiles beautifully...

but am getting weird voltage readings... ive just connected a double set of AA batteires and am getting a reading of 11.8-11.9

im using a 100k and a 10k resistor as per this guide.... obviously i stuffed up something in my math....

this always seems to be my way

source for voltage reader code
https://www.codrey.com/arduino-projects/nano-digital-volt-meter/

@mfalkvidd cheers

ive added that instead but still get the following

call of overloaded 'set(float&)' is ambiguous

final bug

when i try to compile the following code
i Get this error
exit status 1
call of overloaded 'set(double&)' is ambiguous googling tells me that my msg need to be defined better for the purpose but im not sure, as i can see in my void that i have declared it as double, but for some reason it doesnt understant that when i go to send my message

void batM()
{
int Pin; // 0-1023 I/P
double Vin;
Pin = analogRead(A0); // Probe Input
Vin = Pin * (5.0*11 / 1023); // Pin to Vin (Reduction Factor 11)
Serial.print(Vin);
Serial.println(" VOLT DC ");\

send(power.set(Vin));
}

@Yveaux said in Gate controller with Battery Checker:

wait(15601000ul)

champion that works much better thanks

only one bug left now

hi all
below is my code for a gate controller with attached voltage sensor for measuring the battery supply...
it has a relay and a battery checker and that is all

im a little confused to how to change the setup so that the batM loop only runs once every 15 mintues without putitng the sensor to sleep,
i figure i cant put the sensor to sleep as it needs to wait to receive messages from the gateway??
anyone able to advise and let me know if my butchered code can be saved?

   DESCRIPTION
   Example sketch showing how to control physical relays.
   This example will remember relay state after power failure.
   Optional attachment of motion sensor to control the relays is possible.
   Notes:
      -- The Child-IDs of the attached relays range from 1 up to (1-(NUMBER_OF_RELAYS))
      -- Make sure to adjust the potentiometer for triggertime on your motion sensor as leftmost as possible,
         because the countdown will not start until the motion sensor reports back a "0" (no movement)

thanks guys, ill add it to my code tonight and see how it goes

hi all im having issue with the follow code...

i have two devices on pin 2 and 3 on a pro mini but cant seem to get wake working one both...
is anyone able to hint/advise on have gone wrong?

God I'm an idiot. Must of picked up the wrong resistor.

10k resistor won't help me much

ok think i have partially found the issue, when i re did it for a simpler setup, it seems that im measureing temprature of -127 im not even sure what the means, i assume its an error but not sure what its telling me

yeah ive checked that

this is the parsed log below

it presents the temp sensor, but never sends the temp data

hey guys
ive tried to modify two of the built in designs to make them work together, but i think ive stuffed up the dallas temprature probe

the temprature is never updated or sent to the controller

anyone able to advise what ive missed?
i only have the one temprature sensor hooked up

@wiredfrank 100% agree. Dodgy antennas have been the bane of my existence with mysensors. When needing the long range. DO. NOT. CHEAP. OUT.

hey @Tmaster

are you still using this solution?
have you made any improvements or come across any issues with using it over time?

additional note my button is connected between GND and D3 with 470k resistor in the middle

Hi all

thanks for all previous help with this node, im only 1 step away now from getting it to work
the sketch works perfectly untill i introduce the sleep till interupt.....

as soon i uncomment the line for sleep the node starts up then goes to sleep and never wakes up again... and advice is appreciated

Hi all

I know this has probably been addressed before but i cant seem to find any examples of eactly how sleep should be used in this situation

my snippet is as below

sleep(int BUTTON_PIN, int CHANGE, unsigned long ms=0);

im guessing i have my syntax wrong, but cant find any good examples

i keep getting the following error

expected primary-expression before 'int'

basicly i just want the node to sleep forever untill the button is pressed... i know ive got something wrong, but i cant find any examples in the forum that use this verity of sleep

@zboblamont
haha ok so i went right back to the begining of what you said and got it working now (code below)

cut back all unneccicary steps and really locked down what was going on... i can always add back battery part later

however now when it comes back online after 5 minutes for heart beat it keep sending a switch command to domoticz...

im guessing this is due to the issue where the state is being reported differently after it going to sleep as soon as action is performed....

#include <MySensors.h>

// Initialize motion message
MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()
{
    pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as input
}

void presentation()
{
  sendSketchInfo("Lounge Multi", "3.0");
  wait(100);
  present(CHILD_ID, S_DOOR);
}

void loop()
{
  // Read digital motion value
   bool tripped = digitalRead(DIGITAL_INPUT_SENSOR);
   //Software debounce.....
   //wait(25);
   //bool tripped1 = digitalRead(DIGITAL_INPUT_SENSOR);
   //if (tripped == tripped1){}
   //send(msg.set(tripped?"1":"0"),true);  // Send tripped value to gw
   
   if (tripped == HIGH){
   send(msg.set(tripped = 1),true);
   }
   else if (tripped == LOW){
   send(msg.set(tripped = 0),true);
   }
  
  // Sleep until interrupt on motion sensor. Send update every ten minutes.
  sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), CHANGE, SLEEP_TIME);
}

yeah i possibly havent been ecactly clear on that

Scenario is that when i walk into a room i dont always want to ask google to turn on or off all the lights in the room.
so i plan on having wall mounted momentary switches, which their sole purpose is to if the lights are on, turn them off and if they are off turn them on....

so i had planned to use a momentary switch so that no one in the house became focused on if they were off or on, but just push them to get the opposite of current state

In domoticz i was going to use a push on button with a dzvents script so that any time the push on on button became on it would toggle the opposite of whatever the state of lights in the room in...

obviously a bit more logic is needed in case some lights are on and others off....

As per advice i have shortened off the times for delays and have taken out the serial prints on the battery monitor

ok stuck now...

it works once...
it wakes up each time and send the command
but in domoticz im using a push on button with a off delay.....
domoticz is ignoring the sensor after the first on, because the sensor isnt available anymore to receive the command....

do i possibly need the sensor to send an on command, wait a moment then send its own off command again?

Perfect. Tha is for that works great... Interesting thought though with how sensitive it is...

I was actually just waving my hand near it. Possibly 2-3 inches away from the wires....

Could be used as something like a plate you slap with your hand

ok so yeah it does work....but i think its too sensitive

i used d2 in the end for the board im using

but the node seems to trigger every time i even wave my hand near it....

Literally, node is currently setup with two wires you have to touch together to make the switch. when i wave my hand over it it activates
im guesing i need to put a resister in place to decrease the sensitivity? currently its just a wire between 3.3 on a pro mini and the d2 wire

ok thanks for that

so i have modifed as the following....

by the look of the alteration,

i can just put a momentary switch in place between vcc and D3 with a resistor in line and be done with it?

Been a while

getting back into the swing of things finally after a few year hiatus ive started building up my nodes again..

so something simple to get me back in the swing..

Im building a sensor that is literally just a momentary button
should only wake on interrupt....
but i cant for the life of me work out/remember how to get it working in practice.
sensor will be built on easy newbie PCB

Long Term goal is to create using a 3D printers a cover for my existing light switches to put over the top as a toggle so if lights are on turn them off if they are off turn them on, but to have it in a case that is easy to remove incase i have issues, and can get back to the untouched orgiginal light switches underneath

@mfalkvidd ahhhhh That answers my question perfectly....i was just dumping it into notepad ++ ill try that first thing in the morning.

@mfalkvidd yeh i guess so, not quite what i was after the orignal in that version had some good pictures and such of what went where on the board....do doubt i can work it out from an old dead one i have lying around, was just hoping for a nice visual guide to get me back into it.

Does anyone know where we can find the write ups for old revisions? i have a bunch of Rev9 boards that, now that i have restarted these projects after a year break i cant remember the write ups for them....

on the subject of batteries i have to say im really impressed with the setup of these boards....
ive got a DHT and lux resistor measuring every 10 minutes, and i cant even remember how long ago i last changed the batteries...i think its about 3-4 months now....nothing special, just aldi batteries (australian cheap shopping chain)

last check they are still 65%

@dbemowsk cheers mate, thats awesome...now i can blitz out some room based designs

@dbemowsk cheers for that...yeah i have a tonn of old 5v bricks lying around from old nokia chargers, so was just going to try use some of them up without having to buy anythiing else, as i have all of it on hand.... i have some LE33a's which should take care of any step down issues i think?

ahhh thats cool... so use regulated instead and it will pull down the voltage for antenna over that side
...and the board can handle the voltage anyway so it should be fine....

@sundberg84 interesting question...or maybe stupid question not sure...

i have a tonn of 3v pro mini's but im thinking of mains powering some for motion sensors.... would i set it up as battery, and then just use a voltage regulator on where the step up usually would be? or is there a better way to handle it?

@sundberg84 solved the light sensitivity level by swapping the 10k for a 100k...
makes it more acurate in lighter enviroments, but less so in dark enviroments

but by my theory after its a little dim im counting it as dark all the way to full dark for lighting purposes anyway

cheers for all your help....

just a single photoresistor,
i just wasnt sure if there was a way to reverse map the numbers so that if it says 1 it sends 99

photo resistor is now working...domoticz is showing varied amounts of reading though the night and morning....
but its back to front....

its reads 90ish in the middle of the night and this morning fluxuated between 50-10 and is now sitting at 30 with an empty house......did i math backwards? or is this expected behaviour due to the way the resistance works?

in domoticz would i just use low values as my brightness

nah its a 3.3 pro mini
photo

back

ok raw lux is 15

good point...ive used a 47k resistor instead of a 470k, ill change that in the morning
Raw Lux: 15
send Lux: 0

obviously a sensor error, ive moved the photo resistor into diffrent light like 4 times, and no change in reading

this is my current log....

so temp and hum is wrking...but my lux level keeps coming back 0 i think thats what its saying....can i insert more logging on that one to see how its doing the math?

its battery powered, i have the jumpers, i just got registration on node....but not all sensors are sending data....

@sundberg84 would it be possible for you to review the below code....have i missed something?

appologies for the badly worded questions...the code in its example format....
am i reading it correctly that it presents sensors based on the variable for number of temp sensors?

really silly question.....so does create multiple sensors? so i would have temp1 temp2 or does it combine the value of both for an averaged temprature?
the way i read it it would present mutiple sensors i think?

same hear...i ordered from itead...i had to upload the gerbers myself....

@sundberg84 nah just prrof of build at the moment...ill fix them with my proper node ID's when it's build time....waiting on step up's at the moment..... they seem to take a while when you find them cheaper

@sundberg84 champion and here is completed sketch which compiles without errors

@sundberg84 copied a dht library from another computer i used last time i did mysensors work...now ive got that base sketch working....now to add the photo resistor

dht sensor library by adafruit installed version 1.3.0

i did install DHT library...but mine seems to be diffrent, if i manually include it i get dht_U.h

@sundberg84

i copied your github one directly....

but when i try to verify i get the following error
exit status 1
no matching function for call to 'DHT::DHT()'

hi guys so im trying to build my first sensor from scratch, its using the easyPCB @sundberg84 (CHEERS)!

im having issues combining it all for the DHT

i keep getting dht was not declared

so its a battery sensor with a DHT 22 and a photo resistor for lux

here is my code

anyone with advice would be greatly appreciated

hi everyone
im trying to work out how/if what i want to do is possible

i have a heap of 12v LED downlights on 240v transformers in my roof
usually a group of 2-6 per switch....
i would like to know if the trailing edge dimmers can be used in this scenario

@sundberg84 i dont know about you, but i use imperihome as a front end over the top of domoticz with mydomoathome.....that way you get the strong base of domoticz, but i more user friendly and customisable front end

fair enough...i havent done battery sensors before...i was just looking at the API earlier where it pointed out sending in that range so thought it might be in that sort of area obviously domoticz is smart enough to realize its been passed the percentage anyway

@edsteve according to domoticz api data battery is measured in a rang of 0-225? wouldnt percentage send cause issueS?

hi guys i was looking around recently and found this for vertical lift blinds which seems quite thoughrough and well thought out.....

does anyone else think it should be possible to sensorize it?

http://www.instructables.com/id/Programmable-Automatic-Blind-Opener/

am not asking for anyone to rewrite into a sensor but more just wondering if it would be a worthwhile task to re write into a sensor...seems to be perfect for my needs....a very common blind type in australia

confirmed, im now running this is my office, works perfectly every time

i have it set to a motion sensor that covers most of the room...
one relay controls the lights...the other controls my soldering iron perfect work

awesome work...this sketch is brilliant....

what happens if you retrigger motion before timer runs out?
will it always handle a restart of the timer correctly?

ill double check it tonight, but im almost positive i have the pins right....
it was working untill i removed the for part of the loop

this solution has worked perfectly
thanks guys for all your advice...domoticz definatly cant un ignore anyway that i can find either

i have attempted both
the motion sensor now turns on and off on demand by waving my hand in front of it perfectly

but the relay doesnt respond at all....

the node receives the following message
212874 TSF:MSG:READ,0-0-1,s=1,c=1,t=2,pt=0,l=1,sg=0:1
Incoming change for sensor:1, New status: 1

so i know the node receives it, but it doesnt seem to do anything with the message

this is current code

ok im really new at this coding ide stuff...what if i want none of the relays triggered by the motion sensor
i would prefer to link each component back to domoticz by itself, and let it dictate what happens each part seperately...then i can change it easier if i want to leverage other things later

ahhh that makes so much sense now.....

perfect, ill do that tonight... i really should remember to save my sensor files properly

that might be the best way....
as once it has presented to domoticz it doesnt reconize it as a new device again
so clearing eepron may cause it to re present correctly

^ +1 absolutely....i would back this

hi guys

i have a issue with my mysensors gateway

i had a node in that was giving me trouble
so i rebuilt the code and changed the number of relays on it, and added it in and watched it register on domoticz
but after changing it a 3rd time i got really confused on which node it was, so deleted both out of domoticz.
now neither of them appear and im not sure how to get them to re register....

so i planned to now that i have played around a little and gotten to understand a bit more, just resetting mysensors gateway fully so that i can re register all devices and have them reconnect correctly...

is this possible?

hi all
im running mysensors 2.0 with the following code on a node

its a mix of copies of different examples but i think i stuffed it up
i dont see any communication from domoticz when i switch my relays

@mfalkvidd
thanks for that....judging by his operation of the device it shouldnt matter how long its away..seems to be only thing he did was use a static ID, as im guessing it might change if its away for long enough....

seems pretty simple as its a send only device.....
only thing that i can think of that i may want feedback for is to light up buttons when they are available....

not sure if im going to do these as powered by car...or if they should be battery powered...im guessing if battery powered lit up buttons is a bad idea

ok so this is possibly answered elsewhere, and i did look but couldnt find exactly what i was looking for

im thinking of garage remote for the car...
can i create a node that does nothing but sleep unless one of 3 buttons on it is pushed?
im thinking of easy to use car remotes for my garage....
but im concerned about its mapping ability if the device is away form the controller for a couple of days to a week

i was orginally going to make one of these that automattically detected approach of car, but it became too much of a risk

do the devices have lease life times? where they may change there ID without warning...

i will be working with domoticz, and another mysensors node for the actual door operation

worked around the issue but making it a serial gateway instead as long as my nas is happy i dont mind how it plugs in....

ok i can safely ignore my own comment about the mac address....a) no there are no other devices
b.) the model number printed is not the mac address...
there is no mac printed anywhere on he board so im not sure how to create one...
but unless im horribly mistaken that shouldnt affect the DHCP assign of IP address at this stage...

i have attached a better coipy of the picture where you can see my pin locations

hey guys board pic is below....im guessing now looking at it that the mar address for the board dshould be the HR number printed on it?

im aware of the static desirability, i will also have a reservation for it later on...only using DHCP now to try and figure out why its not hitting the network properly...

once this part is done ill be ready to go....
im unable to tell if my made up mac is valid...havent dealt in MAC's before

gateway DHCP

i have a feeling im probably missing something really strait forward
i get the following message

DHCP FAILURE...0;255;3;0;9;Transport driver init fail
now i think debug is already turned on and this is what the above message is.
im using the rmf chip....but im unable to tell which ethernet shield im using, im assuming its the w5100, and im using that sketch at this point....

unsure of what steps to take after this

@hek looks good...thanks for that ill investigate over the next week getting it running

hi everyone
so i have a project for a nfc car starter ive just recently completed....
i was wondering about integrating it into a node so that i could prestart and warm up my car in the mornings....

however ive never dreamed of mysensors before that last few months and prebuilding my own seems a little out of my league....

anyone have any advice on how i could integrate?
thanks in advance to anyone who can give me even a hint
this is running on an arduino nano

that is extremely awesome....
thanks for the time to answer my questions....back to waiting for many ebay parcels...lol

currently after alot of stuffing around ive now got it building without any errors....
but i was just suprised the for an ethernet gateway that there was no setup or loop

i get what you mean about light only receiving so it not needing much work

i would of though gateway to he more complex

hi guys...

feeling like im quite a stupid person here as ive looked though the forum but cant find alot on my issues
ive tried resolving it but im sure i must be missing something

im trying to build the gateway at the moment just to prove i can get it up and running and so i can make sure my domoticz server can see it and run with it

but i cant get it to build
first i tried the codebender version but it told me lots of librarys are missing...so then i installed the librarys from the github site onto my local IDE but it still says librarys are missing even though i can see them
(yes i did install mysensors under manager)

so then i downloaded the github master brance and imported that...

i can get the to build if i use the inbuild example...

but i notice there is nothing under setup or loop which im sure there is supposed to be?

am i just being stupid and missing something?

thank you in advance to anyone who can point me in the right direction
