Error Sending switch command

sundberg84

It (radio init fail) means that when you power it up (connecting it back to PC) it cant initialise radio.
Mostly this is = check wires and/or power issues.

Actions:
Check wires, check wires and check wires :)
Try powering your nano without the relay attached if possible (and see if you get Radio Init fails)
If not - power your relay seperatly if possible (relay often create interferance with radio).

Thanks for the reply, the thing is that I'm powering the Nano via USB from the raspberry Pi (serial Gateway with the external antenna).
The wires I don't think are the problem because it works with the integrated antenna.

Can I power Up the Nano with the Raspbery Pi USB and a 5V Transformer with out burning everything?

From what I remember, parallel tension doesn't sum up, but the current does. Wright?

Will I damage everything, including the Raspberry?

Thanks

Sorry i missunderstood you, you are talking about the gateway, not the node with the relay right?
If so, you dont need to power it seperetaly....

Start with checking your wires...

Hello friends:
Happens to me the same error " Error sending command switch , check device / hardware ! " when I update the device status from the application. HOWEVER from the device button it works well.
I tested with serial GW (internal GPIO ) and GW LAN , with the same results.
The traces of the device and the GW are:

Device type: light node: 3 child: 6

Command Msg GW Msg Device
On button 3; 6; 1; 0; 2; 1; send 3-3-2-0 s=6,c=1,t=2,pt=2,l=2,sg=0,st=ok:1
read: 0-2-3 s=6,c=1,t=2,pt=2,l=2,sg=0:1
This is an ack from gateway

A Someone comes up with an idea?

I have solved the problem. I changes power supply and now it works.

Can someone recommend some power supply?

hugo_pn

@sundberg84 Thanks for the reply.

@NBM

That's great news for all of US with this issue. With how many Amp's are you feeding the Arduino now?

Regarding the power supply, as @sundberg84 has said " Here is a great discussion: http://forum.mysensors.org/topic/1607/safe-in-wall-ac-to-dc-transformers"

I have similar issues with the Relay Actuator and Domoticz

I’m using MySensors 1.5, Serial gateway and domoticz on a windows machine.
Currently latest version: domoticz-win32-2_4078
Working with the standard provided arduino examples.

I cannot get Domoticz controlling the relay. The status is presented in domoticz when I use the RelayWithButtonActuator and press the button

Hardware is detected in Domoticz, devices are showing up (other devices like pressure/humidity are working fine).

I used multiple Arduino pro’s with different NRF’s + capacitator.
Disable Ack results in an error when trying to Switch via Domoticz

The serial output of the RelayWithButtonActuator looks like this:

send: 0-0-0-0 s=255,c=0,t=18,pt=0,l=5,sg=0,st=ok:1.5.1
send: 0-0-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
repeater started, id=0, parent=0, distance=0
send: 0-0-0-0 s=255,c=3,t=11,pt=0,l=14,sg=0,st=ok:Relay & Button
send: 0-0-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.0
send: 0-0-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:

When I press the button attached to the arduino:

This is an ack from gateway
Incoming change for sensor:1, New status: 0
send: 0-0-0-0 s=1,c=1,t=2,pt=2,l=2,sg=0,st=ok:1
read: 0-0-0 s=1,c=1,t=2,pt=2,l=2,sg=0:1
This is an ack from gateway
Incoming change for sensor:1, New status: 1

Any help or a working arduino Sketch would be appreciated.

Thanks

Erik

The logs look ok, doesnt the relay switch when you get this?

Incoming change for sensor:1, New status: 0
send: 0-0-0-0 s=1,c=1,t=2,pt=2,l=2,sg=0,st=ok:1
read: 0-0-0 s=1,c=1,t=2,pt=2,l=2,sg=0:1
This is an ack from gateway
Incoming change for sensor:1, New status: 1

If not My guess its a power problem with the relay.

PostaanErik

Yes it is switching, but initiated from the attached button

sundberg84

But not working from Domoticz and you get "Error sending command to switch" ?
Then nothing in the logs i guess when you try to initiate the command from Domoticz?

Its a trend here.. dont know if that is domoticz or MySensors but if you dont see anything in GW log trying to initiate the command from Domoticz I would ask this question in the Domoticz forum because then its a issue there.

I am not very skilled at these things but I had the same problem for a long time and the only solution I found was to disable ack in domoticz.

select hardware in the hardware/devices tab find the mysensors gateway and click setup.

Try to find your node and deselect the ack box.

Thanks for the input, but this is not working for me :(

Small Update: seems that everything "sending" from domoticz is not received at the nodes.
When monitoring the serial from relay, dimmer, rgb....

when i tick devices in domoticz, a sensor is just not receiving:

send: 31-31-0-0 s=255,c=0,t=17,pt=0,l=5,sg=0,st=ok:1.5.1
send: 31-31-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
sensor started, id=31, parent=0, distance=1
send: 31-31-0-0 s=255,c=3,t=11,pt=0,l=14,sg=0,st=ok:Relay & Button
send: 31-31-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.0
send: 31-31-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:

Hi all,

After trying several things, I decided to try a downgrade on Domoticz going back to Domoticz V2.2563.

Seems to be flawless, Suddenly everything is working fine for the past 6 days.

What do you make of this?

Thanks

flopp

I read this post yesterday and today I solved it.
My GW was restarting as soon as I was sending a command to a MYS node with dimmer child.
I am using nRF PA-LNA, with extra power supply, PA_HIGH. Domoticz 3.8795, MYS 2.1.1. Nano as serial GW.
Tried PA_LOW, new nRF but that didn't help.
Today I found the solution, I disabled DEBUG in GW and now I can't reproduce any restarts.
