Multiple Relays + Motion sketch, fully customizable, optional timer, manual override

[AndreD]

Suppose.
We have a server + gateway + relay module 1 + relay module 2 ..... all relays are on.
There is a power failure at the relay module ..... the relays turned off.
The server status is old, not correct.
The recording of the status of the relay in memory is not acceptable.

[AndreD]

Next problem....
Anybody know how edit sketch for relays to add itrms to send repeate update status to gateway? I want eliminate problem when node start and change status , but gateway is disabled. And after gateway will be enable show in my Domoticz old status/last memory before disable gateway. But after this node has changed status and this status is not show in Domoticz after run. I want to work it as Z-Wave. Z-wave has always actual status. Is any chance to also MySensors Gateway and not has always actual status ?

[gohan]

@AndreD actually the relay state is restored to last state as the node is rebooted. I don't see where is the problem

[AndreD]

Example.

1. The server turned on the relay at 11 hours 00 minutes.
   2.In 11-02 minutes. Alarm with relay module power.
   3.In 11-05 minutes the server sends a command to turn off the relay.
2. in 11-30 minutes. The power to the relay module resumes. (Relay Enabled)
3. Server status is off (Relay is on)
4. The result - the neighbors below are happy to repair: (

Question. How to request real relay status from the server.

[Boots33]

@AndreD have a look here for a bit of info on requesting status.

I'm having trouble getting Domoticz to see any more than 1 relay. I've tried the MySensors example basic relay sketch and no luck. Then I tried this one (which is amazing btw as I want to have a PIR independent of the relays) and the same problem.

I've tried to present the sensors individually without the FOR statement, and added a delay between presentation in case that was an issue, also I've tried different output pins on the Arduino, and I've tried multiple boards... Nothing has worked

I am very much an enthusiastic amateur, so any advice on what to try next much appreciated

Thanks in advance

@Ben-Andrewes My domoticz instance behaves weirdly with relay sketches too. Maybe you can find some help here: https://forum.mysensors.org/topic/7101/domoticz-relay-node-doesn-t-show-up-in-devices/21

[Ben Andrewes]

@thierryd Thanks for the reply. In case it helps anyone I ended up individually defining and presenting the relays and their parameters within the sketch rather than using the FOR statement and it worked fine.

[gohan]

Did you try to add a small delay in the presentation?

[Ben Andrewes]

@gohan - yep added wait(100) between each sensor. To be honest I made a number of small changes without re-uploading and testing between so I'm not sure what solved it... Oh well, at least it works now :)

[Ostoja]

Hello! Sorry for my english. This sketch works fine. But I still need to add a temperature sensor ds18b20. If I add a temperature sensor, the sketch stops working. Please help. I'm new to both Arduino and Mysensors. Many thanks!!!

[rejoe2]

@ostoja Please add your code. Most likely you just transfered the DS18x20-Code into the relay sketch including the sleep() at the end of the loop().
If you did it that way: This had been discussed here several times, you have to change the code into a so-called non-bocking loop().

I commented out the "sleep", but when I press the relay switch in Domoticz, it does not work:white_frowning_face:

@ostoja said in Multiple Relays + Motion sketch, fully customizable, optional timer, manual override:

// Present all sensors to controller
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i, S_TEMP);
  }

  // Register all sensors to gw (they will be created as child devices)
  for (int sensor = 1; sensor <= NUMBER_OF_RELAYS; sensor++) {
    present(sensor, S_BINARY, "Relay", ack);
  }

With this two "for" loops you set present(n) multiple times. in the first for() you start with 0 until MAX_ATTACHED_DS18B20-1, in the second for() you start with 1 until NUMBER_OF_RELAYS-1, so this will assign the sensors with identical IDs as the relays.
I have not checked the internal code of this method, but I would think that you should better user a different range in the second for() loop starting at least with MAX_ATTACHED_DS18B20+1.

Additional remarks:
For the relays better start with 1.
Shift the Temp values to higer range (use e.g. a variable like FRIST_DS_SENSOR_ID).
Check, if the receive()-part and the ID you get really fits together with the relay you want to switch.
Don't try to read the temperature values every few parts of a second. Use a millis()-routine.

Please search the forum, there have to be at least 2 threads with exactly the same problems in which I posted how to solve this. You are "trying to reinvent the wheel". :grin:
