multiple DS18D20 does not report temperature

[hek]

Make sure both temp sensors has been created on Vera by starting inclusion mode on vera and restart the node a few times (5 seconds apart).

Reload GUI on vera.

Check debug log on sensor that communication is working.

[Tomasz Pazio]

made all accept debug log.
unfortunately fail, next thing, last update time change only after re-plug arduino, it is not changing recurrently every 30000ms

[Tomasz Pazio]

and log

Today after vera update I do not have any readings from temp.sensors on onewire eaven one...
when using "generic " example for arduino all sensors are reported.
Something wrong with this example :(

[hek]

From the log above it looks like at least 2 temp-sensors were found (and presented) to your controller.

[Tomasz Pazio]

so something wrong with presenting readings :( what to check on vera side?

[hek]

If you continue monitoring the nodes log. Does it send anything after the log you posted above?

[Tomasz Pazio]

no, only this one, and nothing else.

[hek]

That seems wrong.

What if you update the libraries and sketch to latest on github. There was an update to the Onewire/Dallas library recently to make in none-blocking...

[Tomasz Pazio]

log is now different
send: 3-3-0-0 s=255,c=0,t=17,pt=0,l=3,sg=0,st=ok:1.5
send: 3-3-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
read: 0-0-3 s=255,c=3,t=6,pt=0,l=1,sg=0:M
sensor started, id=3, parent=0, distance=1
send: 3-3-0-0 s=255,c=3,t=11,pt=0,l=18,sg=0,st=ok:Temperature Sensor
send: 3-3-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.1
send: 3-3-0-0 s=0,c=0,t=6,pt=0,l=0,sg=0,st=ok:
send: 3-3-0-0 s=1,c=0,t=6,pt=0,l=0,sg=0,st=ok:

but still no readings on vera :(

[hek]

I cannot see any temp readings in the debug log...

Are you powering your 9 Dallas sensors directly from the Arduino or separately? I'm not sure how much they draw but 9 is quite much...

[Tomasz Pazio]

Now trying with one and two. No more.

[Tomasz Pazio]

There are two parts of issue:
problem with no data on vera was on this part:
// Only send data if temperature has changed and no error
#if COMPARE_TEMP == 1
if (lastTemperature[i] != temperature && temperature != -127.00 && temperature != 85.00) {
#else
if (temperature != -127.00 && temperature != 85.00) {
#endif

my reading is now -127.00
changed to -200 and now I can see the data on vera.
however this is not correct data because should be something like 27 Celsius.
so there is something with conversion as well :(

[hek]

-127 means something is wrong when reading your dallas sensors. It is a an error code. So you actually only have an issue with your temp sensors.

[Tomasz Pazio]

when I use Example for Dallas multiple sensors it works fine.

when I use example for one-wire temperature sensor ds18.... it works fine as well
so i can reed but can not use Mysensors sketch :(

[hek]

Very strange. Are you using the same OneWire library in both cases?

[Tomasz Pazio]

yes the same.

[Tomasz Pazio]

any idea?

[hek]

No, must be hundreds of users running Dallas sensors here. Trying to figure out if anything has changed in the library/dependencies but I don't see anything except the thing I mentioned earlier here.

And you can get the sensor running without MySensors library loaded...

Guess I have to hook up a Dallas sensor myself to check (tomorrow or so..)

[rvendrame]

Are you powering your Dallas sensor using the 'one-wire' method? Is your arduino 5V or 3.3V?
