Unfortunatly the sensor stopped working last night. I have ordered a relais board with opto coupler....
I will keep in touch

Again, thanks all for answering

Until now its working 2 days flawlessly.

Going bonkers is probably not the right word. I actually meant that the owner, and especialy his wife, are going bonkers :-)
What I meant is:
When I connect the led: (red = D5, Green = D6 and the ground is connected through a resistor of 1K.) When I turn on the relay it's answering for aprox. 5 minutes and than it crashes.
I can only reanimate it by turning off the power

Thanks for your quick reply.

The led is indicating one colour at the same time. Green for open and red for close.
I can give it a try to have more resistors connected...

Hi,

I promised to keep in touch.... :-)

I have disconnected the radio from the Arduino, so the radio is fed through a seperate stable 5V.
And also the relais board is fed seperately.
It runs for a cuple of days and it seems to work well. Time to move on.
To see if the magnet is working or not, I decided to connect a RGB led. When I connect the led, the board is going bonkers. The led is connected on D5 and D6 and the other side to ground (via a resistor)

Anybody a clue?

To all,

Thanks for your answers. Unfortunatly I didn't have time to check your answers. I will keep in touch

Hi,

Picked up the hobby again :-)
I would like to build an irregation system with a pump, 4 valves and a sensor to easure the total amount of water in a tank.
I have found some sketches to help me with the problem. So I hope this would not be the problem.
I now have tried the relais sketch on my doormagnet (other project), and after a while it will fail (probably noise causes the problem)
My system is:
Arduino nano
radio NRF2401 PA/LNA
NRF24L01+ Socket Adapter Board
relais board
All of this are connected with jumper wires and the arduino + radio are fed seperatly with a charger.

Before I try to build the irregation system I would like to know if there is a good method to calcuate the size of the decoupling capacitor. And where do I have to put it. Do I have to put it on the 230V side, or also on the 5V (on the relais board)

Hope too get some aswers here, thanks in advance

update:

Adapted the old distance sensor sketch to the 2.0 library and upladed it and connected to my PC. Also connected the gateway 2.0 to raspberry (Domoticz).....
Allright it works....I do get distance in my serial monitor and in domoticz.

Now try to upload the basement alarm sketch...See what happens...

Hi

First of all, thanks for all the answers.

Started from skratch again. Downloaded the new arduino IDE.Some Libraries (NewPing and Mysensors) and finaly the sketch compiled :-D
I uploaded it to the Nano and then expected to see something on the serial monitor....

Too bad...Oh right. removed slashes for MyDebug and MyDebug_Verbose...

Presto.

Unfortunatly I see in serial monitor:

Too bad. What have I done wrong? Is it possible to see the distance in serial monitor and to see if a relay turned on or off?

EDIT:
Upgraded my Gateway also to 2.0

Stil no succes :-(

I turned of the LED pin (I don't need it)

The compiler does his job till the last line:

which returns:

What can I do to make this error disappear

Thanks in advance

Hi back again,

Tried to upload the sketch. unfortunatly the copiler returns an error:
'sendSketchInfo' was not declared in this scope
Googled for an answer. And found an solution, for installing a new library.
I installed:
MySensors 2.0.0
Mysensors_development
But it doesn't work.

Can you help me please

Thank You all,

I will try the sketch (and try to understand it....LOL)
I need only need to measure the water level once or twice a day. So I will figure it out how it has to be done.

Thanks again

Hi,

As the title already mentioned, I would like to build a sensor which will measure the waterlevel and send it to my gateway. If the waterlevel is sufficient, my gateway has to send the signal to open the valve and start the pump.
I would like to use a combination of 2 scripts (Relay and distance sensor)

I have tested the sketch, but it only returns a distance when I press a button in Domoticz.

The sketch I've used:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

Please could you help me, to combine the sketches and help me with my learnig curve ;-)

You're brilliant.

It works like you said.... Red if the door is closed and green when it is opened

therefore I have adapted the code a littlebit:

if (message.getBool()== true)
is now:
if (message.getBool()== false)

Thank you very much

Hello,

First of all I would like to thank you for the good work you all are doing.
Since I have been attended to this site, I am thinking of making a relay board with a status signal.
What do I mean:
I have a magnet which is working on 12V. I have this magnet installed to my door, so it is possible for me to close the door by magnet.
From the site I have downloaded the sketch for operate a relay board, so it is possible for me to operate the magnet (with a relay) from Domoticz. It is already up and running.
Unfortunately the magnet doesn’t have a status led, so it isn’t possible to see if this magnet is working or not.
When I’m searching on the internet, I see several sketches to operate a led via some pins on the Arduino.
My question is:
Is it possible to integrate some code in the relay sketch to operate the LED.
For your info, I have a RGB LED which only have to work with the colors green and red.

I have done some fiddling with the code, but it doesn’t work I think:

• modify it under the terms of the GNU General Public License
• version 2 as published by the Free Software Foundation.
