Dallas temp sensor in Fahrenheit, must be celsius

sundberg84

If i read the log correctly: send: 0-0-0-0 s=0,c=0,t=6,pt=0,l=0,sg=0,st=ok: is a request for Metric/Farenheit but the controller does not seem to respond.

You should have something like:

read: 0-0-2 s=255,c=3,t=6,pt=0,l=1,sg=0:M

Strange. I can not see what goes wrong.

I updated the sketch to just use Celsius.

Replace this (for the Temperature sketch) from:

 float temperature = static_cast<float(static_cast<int((gw.getConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;

With this

 float temperature = static_cast<float>(static_cast<int>((sensors.getTempCByIndex(i)) * 10.)) / 10.;

Related to this topic and the fact I used CodeBender I guess somewhere there is the problem.

The IsMetric function doesn't seem to work.

I tried again to get it to work with the original sketch.

1. send: 0-0-0-0 s=255,c=3,t=15,pt=2,l=2,sg=0,st=ok:0
2. send: 0-0-0-0 s=255,c=0,t=17,pt=0,l=5,sg=0,st=ok:1.5.3
3. send: 0-0-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
4. sensor started, id=0, parent=0, distance=0
5. send: 0-0-0-0 s=255,c=3,t=11,pt=0,l=18,sg=0,st=ok:Temperature Sensor
6. send: 0-0-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.1
7. send: 0-0-0-0 s=0,c=0,t=6,pt=0,l=0,sg=0,st=ok:
8. send: 0-0-0-0 s=0,c=1,t=0,pt=7,l=5,sg=0,st=ok:66.6

Should the M appear in line 7?
What is deciding in going for Imperial or Metric?
Can anyone help me out?

You should get a in INTERNAL/I_CONFIG message from controller. With a payload of "M".

Line 7 is the presentation message from your sensor (c=0=PRESENT).

I cannot see any incoming traffic from your gateway.. Do you have some kind of communication problems? You should have a look in the gateway log.

Petjepet

Line 8 is giving the temperature and will keep doing this.
It is also accepted by my controller (Pimatic on a RasPi) and therefore I did not think of a communication problem.

Where can I find this gateway log?
I'm pretty new to this so still learning :smiley:

hek

You might wanna check with the Pimatic plugin developer here (in the Pimatic sub forum) or in the Pimatics community.

Is this the gateway log?

I do not see a INTERNAL/I_CONFIG message.

Petjepet

Got it working now :smiley:

I installed Arduino software and mysensors api again.
Reloaded my gateway from this install.
On the node ran the EEPROM sketch from mysensors library and reloaded the DST sketch from also the mysensors library.

I think something went wrong in library updated Arduino suggested.

@hek Is it essential to work from the mysensors library (as distributed in the api) and keep that as a stable set and ignoring library updated suggested by the Arduino software?
And when updating libraries they will updated in a My Documents folder causing Arduino software to generate issues on compiling of having libraries twice. What is the way to work on this?

You got a bigger chance of getting help if you keep the versions in the distribution.
But it's not optimal in any way. Would've been nice if the IDE would have some sort package manager like Node where version could be specifed.

Petjepet

I agree.
It is very hard/difficult to keep a consistent set of libraries operational in a broader scope of elements to be managed.
