Never seen the request function.

You can find request and other useful info on the API page.
Hope you are enjoying your MySensors journey

@moskovskiy82 Have a look at my Fire pit RGB striplight controller, The Mosfets in that project run very cool (can't detect any heat rise at all) with 10m of rgb strip lighting connected.

To achieve my goal (node that sends relay state after power failure to sync with domoticz)

Have a look at the sketch I used for my Synchronising Light switch you may be able to use some of that code perhaps.

@Ron said in 433MHz Transmitter FS1000A stops working when connecting antenna:

I could try it with a cable of length 170mm but I am not sure if that is anything >else than with the antenna.

Yes you should experiment to see. That is the best way to find solutions when you are a "Maker"

Does the transmitter also needs more voltage when an antenna is connected?

Sorry I am not an RF engineer so am not sure on that, although I would have thought you would achieve best results with an antenna of the correct length connected. As i said previously I know they work better with a higher voltage.
From memory (you should check) I think they are good up to 12v

At the moment i just connected it to the 5V output of the arduino. Maybe that is >too low for the transmitter with antenna.

You should use a multimeter to check the actual voltage. The clone arduino's are sometimes prone to be a bit low on their 5v line as are some computer usb ports, especially if you have a few other devices (keyboard , mouse, speakers etc.) connected as well.
Power problems are a common source for causing trouble I always try and power my nodes from a dedicated supply to eliminate this issue.

I ordered some boost converter to test with higher voltage. Maybe that helps a >bit

Your simplest solution may be to power the test node from a 9v battery. You can supply 9v directly to the arduino VIN pin and also 9v directly to the FS1000 power pin instead of the 5v line. This will at least let you know if it is a power issue.

It is also not unusual for these type of remotes to fire off a burst of on or off signals instead of just one transmission. This gives them a better chance of getting the message through.
So if you are not doing that already you could try sending a few times separated by around a 10 ms delay. You may need to experiment a bit to see what works best.
I know one remote I was working with sent the message 6 times separated by 13 ms.

@skywatch said in Lightning Detection:

Hi,

I have a lightning detector with analog and digital outputs. I would like to use the analog to see the amplitude of energy to help determine distance to strike.

Question is, what would be the best sensor 'type' to choose for this? I would like it to be shown as a graph in MyController with 0-100%, but not with humidity symbols. There is a generic digital type, but no generic analog type (maybe an idea?)....

Thanks for any suggestions

In Domoticz S_DUST, V_LEVEL are a good combination to use for generic sensors. You can easily use this for percentage etc. and it will give you a graph as well.

To use S_DUST was first mentioned by @pjr in This Post

I have used it in my Water Tank Sensor to show both litres and percentage and in my Lightning Sensor to show distance and intensity.
It may work in other controllers as well, I guess it will depend on how it is implemented in the plugin.

@Ron The hole on the corner is the usual place to connect the antenna.
When using these in the past I have found that a straight piece of wire with a length of 170 to 175 mm gave the best results. Also note that while the fs1000 will work on 5v it really needs 9v or more to get good results. You can also swamp the receiver by getting too close as well. i would think with your sockets in the same room you shouldn't have any problems though. Maybe check that the vcc is not dropping too low.

@zboblamont it certainly has been a bumpy road for you. good to see you making some headway.

@sigolhi Even if you can get the nodes to connect without a gateway you may still have issues trying to run them on batteries. Any node that is expecting to receive a message cannot sleep so will be rather heavy if on batteries alone. You may also need to add solar charging as well.

@Dick in your receive code you are not testing for which child the message is for, so both are being switched.
You need to test what child the incoming message is for using message.sensor

Try something like below.

Also is there any reason you are still using MySensors V1.x

if (message.type == V_LIGHT) {
  switch (message.sensor) {
     case CHILD_ID_1:
         // Change relay state
        state1 = message.getBool();
        digitalWrite(RELAY1_PIN, state1?RELAY_ON:RELAY_OFF);
       // Store state in eeprom
       gw.saveState(CHILD_ID_1, state1);
      break;
  case CHILD_ID_2:
      state2 = message.getBool();
     digitalWrite(RELAY2_PIN, state2?RELAY_ON:RELAY_OFF);
     gw.saveState(CHILD_ID_2, state2);
     break;
  default:
        Serial.print("Incoming sensor unknown");
    }
}

@MasMat said in Momentary button to control lights:

I'm trying to figure out the "switch"-function, but Mysensors-docs nor Google cant find much.
I'm trying to figure out how switch=>case works.

the switch/case is a standard arduino function. It can be very useful and sometimes much neater than using multiple if then else statements.

I could use that to further my one (and two or more!) button remote.

Yes it is well suited to that task.

Where I get lost is why "case 4" is completely different from the other three?

Any advice?

Is it this you are referring to

case 4:
         groupState = !groupState ;                   //Toggle the state
         send(msg.set(groupState), false);     // send new state to controller, no ack requested
         tone(buzzerPin, 1200, 60);                  //Play short beep to acknowledge touch
         break;    

The first three case statements are sending direct node to node messages which are handled by the receiving node. The case 4 code is simply sending a standard binary switch message to my controller (Domoticz) and toggles the state of the switch in domoticz. I have that one switch set up as a group control switch in Domoticz so it turns on/off several light nodes at the same time. Sort of like a master control switch.

As i indicated in that original post the sketch was still in it's early testing stages. While I still have not completely finished the project yet it has been out in the garden for some months and has shown no false triggers from either rain or even birds landing on the touch pad.

Hope that helps. feel free to ask if you require any more info. MySensors node to node messages are really quite flexible once you get the hang of them.
