Error Sending switch command

[sundberg84]

@hugo_pn If you are using the default relay sketch you need ack back from the gw to switch it. Is the problem in Domoticz (Error sending switch command) or it doesnt get switched?

[hugo_pn]

Hi,

I am using the default relay sketch with button.
Ack back = acknowledge?

The message I receive from Domoticz is (Error sending switch command...)
when the message doesn't appear it switches.

[sundberg84]

In new Domoticz beta there is so you can enable/disable ack. Havent tried that myself but maybe you can try to change that.
Also what does your gw serial log say? Maybe we can find some clues there...

I'm having the same issue, running Version: 2.3530 Build Hash: 9eef872

The sensor is number 1, and as soon as i try to change the state i get the "Error sending switch command, check device/hardware !"

This is what the domoticz is sending:
0;0;3;0;9;send: 0-0-1-1 s=35,c=1,t=2,pt=0,l=1,sg=0,st=fail:1

It seems that the problems is that the sensor does not reply correctly, how do i parse the message and reply?

Thanks

st=fail means that the message was not received. So this is a hardware issue

Hello guys,

I had the same problem with st=fail, also with this output: "Error sending command, check your hardware/device (blablabla :D)". I can give you here my hints, maybe they will help you. First of all I am using the latest beta domoticz and beta mysensors library v1.6.

I am using two types of nrf24L01+ (with built-in antenna and external). For built-in antenna I am using #define RF24_PA_LEVEL_GW RF24_PA_HIGH in my sketches, BUT for external I need to lower the power because Arduino cannot provide enought current for it (even with attached capacitor): define RF24_PA_LEVEL_GW RF24_PA_LOW. I had this st=fail when I was using HIGH settings for nrf with external antenna, but now it is fixed. Also make sure that you have enough coverage.

I have Arduino Mega2560 installed 1 week ago with 16 channel 12v relay board together. I had the the same problem like you "Error sending command, check your hardware/device". Two days ago I realized that maybe there is a problem with my powering my gateway. I have RFXtrx433, APCups and Ethernet Arduino Uno gateway connected to Raspberry Pi USB. I connected my MySensors gateway separately via 5V charge to the wall socket and this error problem is gone. Conclusion was this that my Raspberry couldnt supply enough current for all attached devices. Now I am planning to install PiHut USB hub with external power supply and move all connected USB interfaces to it and then just with one connection cable to my raspberry (maybe RFX will work better :) we will see).

Update us if these two hints helped you ;D.

Cheers
Maciek

Sorry for not replying but the error hasn't been appearing, só I cant show the log. From what I've read there is no log file in Domoticz.

Haven't tried to enable/disable ack.

This may come into a great help, I have two external antennas that I thought where damaged since arrival, maybe this is the problem. I'm going to try this next week.

Although, this still makes me thinking of distance, the error appears with the hardware separated by +- 3m with no obstacles .

@macieiks Could't find what my problem was. I've tried changing the gateway code to the sensor, same issue, change the radios, the same thing.

I ended up downloading again the Mysensors library, the same issue, i then changed the baud rate for the debug and serial gateway to 19200 and that seemed to solve the issue, i can now issue commands to the nodes, thanks for the help.

My sensor and gateway are all Pro mini, 8v 8Mhz, i remember now that i've read something in the forum, but can't find it now.

@hugo_pn Is's possible to see the sketch? Im insecure where to alter the sketch.

@NBM

Hi,

I'm trying to find it. As soon as I do and if I do I'll tell.

Hi,

Can't find the specific line. The most similar one is in the MyConfig.h line 115

#define RF24_PA_LEVEL_GW RF24_PA_LOW

Going with the GitHub file I don't even find it...

Where exactly did you change the mentioned above?

Thanks

Hugo

P.S. I can't find the V 1.6 library for my sensors. That's why I mentioned github

[hek]

1.6 is the default branch when you go to the github project.

This is what im getting when im trying to turn on the light.

[sundberg84]

st=fail means the gw radio doesnt reach the node.
It can be a power issue (search the forum) which can be fixed with caps and/or other power.
It can be a range issue and then you need a repeater.

[NBM]

@sundberg84 The node is 2 meters from the gateway.
It most be an power problem. Is it with the gateway or node?

[sundberg84]

Hi!
Can be both (or even worse, faulty hardware/bad fake nrf radios).

I power my gateway through USBCharger and have a 4.7 + 47 uF cap paralell on VCC/Gnd.
On my nodes i use a single 4.7uF cap VCC/GND

In best case its just one of your radios thats bad or misswired... check wiring and/or change the radios if you have another one.

[NBM]

@sundberg84 On my gateway (nano) is an 4.7 uF og it is connected with USB to the domoticz. How can I do it different?

Im getting this from the node. It reads okay.

Read is not the problem. it is send comands

[sundberg84]

I had this problem due to range but 2m shouldnt be any problem... so strange you can recieve but not send.

Some things to consider if someone else doesnt know better than me:

• Change radios if possible
• Send commands without relays attached (to see if there is some spokes or disturabnce from relay)
• Connect MYSController to debug if possible

Whats your node ID on that node?
Im not good reading those serial lines but if they are beginning with 0 its like its sending to the gateway!?
In my case when i send: 103;1;1;1;2;1 where 103 is node ID, Child(Relay) 1, MsgType = 1 (Set), Ack = 1 (yes), 2 = V_LIGHT, 1 = On
