DS18B20 And fibaro binary Sensor No temp indication

This is an update. I have submerged the sensor into a water boiler and after a few moments i got a first reading of 61.50 degrees Celcius witch seemed correct.

After that i left the boiler off and waited to cool down. After 10 minutes the temp was still stuck at 61.50 C which sounded strange.

I Then filled up the boiler with cold water and submerged again the sensor. It took around 10 to 15 minutes for a value update to 28.25 C which also seems correct.

My configuration settings are:

Interval between successive readings: 30s

Interval between forcing to send report concerning the temperature conditions: 60s

Temp Report on Value Change 1

Any idea if this is a known bug of the sensor? the readings should be much faster.

Also the default value when the sensor is paired for Temp report interval is -56s ??>

Hi Karolos,

I have the same problem with this device. I have two DS18B20 connected, which give correct temperature values, both only every 16-17 mins (1000 sec?), no matter the settings of parameter 10, 11 and 12. I have tried different values for these parameters, both no changes in frequency of the temperature readings. Also these parameters need to be set with a value between 0 and 255, but any value above 127 returns a negative value setting (128 will return -128, 255 will return -1)????. Have you found a solution?

Regards, Emiel

Hi Guys

i see the problem is now over 2 Years old....and i run in the same Problem.

I tried everything to get faster updates. But nothing.

A case is open!!!

Parrall i opened a case with fibaro.

For me the temp sensor is critical because it is stearing my Solar Water Pump. If the sun rises the temp inceases in 10 Minutes over 40°. Every 26min a new value is a liitle bit to slow.

With the new fibaro smart implant it works,

Thanks for the quik answer

do you use the smart implant with an 18b20 sensor or with the fibaro combi sensor temp/humanity ?

regards Chris

I ordered some smart implant and hope that it will work.

Zipato is working on it....but you know threre is no one who can fix the problem.

From Fibaro side the case was closed: We do not have any problems withe the sensor and you are using a zipabox which is not supported. Nice Answer.

I thought that the interoperability was the master argument againts some proparitäri solutions.

But nothinks works together. This is the case nr 10 which zipato cound not solve.

Chris

Was is a not supported zipabox?

Correct

The Fibaro side closed the case because we are not using there home Gateway. With there gateway (fibaro home ceenter) they don´t have problems.

I read in some foren that some others have the same problem with these sensor (open hub).

It might be that we have some problems on the zipato sight. Zipato is working on it.......

I have same issue. 4 temp sensors DS18B20 are pared properly with Zipatile via Fibaro universal binary sensor. The temp reading interval is not reacting to the settings I do; the minimum I was able to get - each 10 minutes the temperature is updated;

Dear Zipato, was something done to fix this issue since then?

I have finally got it working. Steps to bind worked for me:

1. connect the sensors to the binary sensor

2. readd the device in z-wave network

3. go to device configuration and press re-apply device descriptors

4. go to configuration tab and set required parameters (I set the read interval to 1s and report interval to 5s. Save

5. go to the advanced tab and press configure node

after that I found my temp values frequently changing, each 5 seconds;

Good luck
