Strange value being sent from controller using mixed temp/relay node

cayco

Hi! I'm starting to play with relay and I experiencing somethings similar. I have 3 sensors (two of them works great, just temperature, volt, light and humidity) one is relay sensor. First of all it just doesn't react to my commands:

mosquitto_pub -p 1883 -h 10.0.0.11 -t MyMQTT/22/1/V_LIGHT -m "1"

serial shows just this:

connecting at 115200
repeater started, id 22
send: 22-22-0-0 s=255,c=0,t=18,pt=0,l=3,st=ok:1.4
send: 22-22-0-0 s=255,c=3,t=6,pt=1,l=1,st=fail:0
send: 22-22-0-0 s=255,c=3,t=11,pt=0,l=12,st=ok:Relay sketch
send: 22-22-0-0 s=255,c=3,t=12,pt=0,l=3,st=ok:1.0
send: 22-22-0-0 s=1,c=0,t=3,pt=0,l=3,st=ok:1.4

I'm using stock http://www.mysensors.org/build/relay code, just setting node_id manually to 22.

On the controller I have:

0;0;3;0;9;read: 21-21-0 s=11,c=1,t=0,pt=7,l=5:23.0
publish: MyMQTT/21/11/V_TEMP 23.0
0;0;3;0;9;send: 0-0-21-21 s=11,c=1,t=0,pt=0,l=7,st=fail:23.0001
0;0;3;0;9;send: 0-0-22-22 s=1,c=1,t=2,pt=0,l=7,st=fail:13.0001

It looks like it tries to send '1' with garbage from last sensor read.

It does this with my humidity sensor:

publish: MyMQTT/21/12/V_VOLTAGE 5001
0;0;3;0;9;send: 0-0-21-21 s=12,c=1,t=38,pt=0,l=4,st=ok:5001
0;0;3;0;9;read: 21-21-0 s=10,c=1,t=1,pt=7,l=5:52.0
publish: MyMQTT/21/10/V_HUM 52.0
0;0;3;0;9;send: 0-0-21-21 s=10,c=1,t=1,pt=0,l=8,st=fail:52.05001

I am also using MQTT client gateway which @gadu recommended me.

I did not understood how does this workaround @Gambituk mention work. Do you know what is going on above? What am I doing wrong?

P.S. Using standart EthernetGateway code also scrambles messages (please note strange sing after '1'):

0;0;3;0;9;read: 22-22-0 s=255,c=3,t=11,pt=0,l=12:Relay sketch
0;0;3;0;9;read: 22-22-0 s=255,c=3,t=12,pt=0,l=3:1.0
0;0;3;0;9;read: 22-22-0 s=1,c=0,t=3,pt=0,l=3:1.4
0;0;3;0;9;send: 0-0-22-22 s=1,c=1,t=2,pt=0,l=2,st=ok:1à
0;0;3;0;9;read: 0-1-22 s=1,c=1,t=2,pt=0,l=2:1à
0;0;3;0;9;read: 21-21-0 s=12,c=1,t=38,pt=4,l=4:5023
MyMQTT/21/12/V_VOLTAGE

0;0;3;0;9;send: 0-0-22-22 s=1,c=1,t=2,pt=0,l=2,st=fail:1à

after this relay node does not accept any message (you can see st=fail on the last line - that was me retrying mosquitto_pub -p 1883 -h 10.0.0.34 -t MyMQTT/22/1/V_LIGHT -m "1").

Sorry, i just saw this, do you still have the issue or is it resolved?

cayco

I still have it. I need to check how this is (not)working in single sensor environment. I will laso try not to set IT manually. Only if I get some tim to do it...

cayco

I have reconnected it again and it did just starte to work as it should from the start. I changed nothing. Strange...

Gambituk

What i think happens.. in my own way of thinking!

                      1 2 3 4 5 6 7 8
                      B a d v a l u e      something longer than expected
                    1 1 . 4 v a l u e        next value is 11.4 but longer value stays in a register somewhere
                    2 1 . 6 5 7 l u e       and is mixed with the next value -
                    1 2 . 5 5 7 l u e       until restart or overwrite -

So i think there is something that needs to be changed to control the length of expected values or actual values to adapt to whatever data arrives.

For my workaround, send 1.0 and 0.0 instead of 1 and 0 seems to force the sketch to round the value to 1 or 0 even when there is "1.0dvalue" as the received instruction.

http://forum.mysensors.org/topic/524/mqtt-client-gateway/29 There is a proposed solution in the following post, i will test and see if it helps, and report back.

Gambituk

Initial tests seem that it is now resolved with the fixed version of the mqttclient gateway as modified by fotofieber

I try this code on pro mini with Vera3 but then I implementing it I have a DOOR Switch instead of Ds18b20. So is it possile to show temperature on vera and what's wrong?

repeater started, id 1

@tjay4x4

We can't help you much without any code.

tjay4x4

Sorry. :) Hek, I using this code. Vera3 find relay and it works, but also appears 3 door sensors instead of 3 temp sensors.
I try to use the my arduino board only with sd18b20 sketch and it work's and show temperature. Is it sketch suitale for vera?
