Fibaro Universal Binary sensor wrong temperature, no outputs

[Domosapiens]

Elektrotek,

Regarding my fibaro software, it shows exactly the same library, protocol and application version as yours.

Find below the code of one of my FGBS001 sensors as in my zwcfg_0xnnnnn.xml.
Looking at it, line by line, can you find any significant difference?

When you use the inputs 1 and/or 2, polling must be on.

Hope this helps

When you use the inputs 1 and/or 2, polling must be on.

Hope this helps
Domosapiens

Thank you Domosapiens,
Apart from the fact that you use 4 sensors instead of one, the only difference is the part in bold, which is totally missing in your file:

name="COMMAND_CLASS_SENSOR_BINARY" version="1" request_flags="5">

Mine:
name="COMMAND_CLASS_SENSOR_BINARY" version="1" request_flags="5" innif="true">

The rest of the code is the same.
Thank you very much Domosapiens. Can be the cause of this using OpenZwave?
Is anybody using OpenZwave with Fibaro universal controller with Domoticz?

BR,

I don't know what innif means but I think it's not relevant for your temp problem.
"COMMAND_CLASS_SENSOR_BINARY" is related to IN1 and IN2

The relevant part for temperature is:
<CommandClass id="49" name="COMMAND_CLASS_SENSOR_MULTILEVEL" version="1">
here you need to see 1, 2, 3 or 4 sensor items

Is anybody using OpenZwave with Fibaro universal controller with Domoticz?

Postby Domosapiens » Mon Jul 27, 2015 8:13 pm
I have 4 of them working with Domoticz like a charm, for almost 1 year (?) now.

Domoticz is using OpenZwave.

In the meantime I share your disappointment, I discovered also a problem.

I have 4 of them working for a long time.
Two are under installation (DIN rail housing), so no result yet.

Number 5 works in the mean time correctly.
Number 6 has problems. No temperature sensors are detected. IN1 and IN2 are working correctly.
Exclude/Include gives a new Z-wave ID but no temp sensors.
Hard reset (Exclude, power off, button pushed, power on, pushed for 10 seconds, power off, release button, power on, Include) does not help for temp sensor detection.
No "COMMAND_CLASS_SENSOR_MULTILEVEL" in the zwcfg_0xnnnnn.xml.

Number 5 left, number 6 right:

20151002_122609_small.jpg (230.8 KiB) Viewed 3222 times

Unit number 5 and it's temperature sensors, in the housing of 6 works correctly:

20151002_122917_small.jpg (243.96 KiB) Viewed 3222 times

That means:
- The infrastructure of 6 is OK.
- FGBS-001 number 6 is defect OR,
- one or more DS18B20 temp sensors of number 6 are screwing the protocol
I still have to exclude the last one, before I declare the FGBS-001 "Defective on Arrival"

they have always voltage (2,6-3V). Is it normal?

Yes, this is normal (average voltage of the communication protocol)

Hope this helps,
Domosapiens

[Elektrotek]

Thank you for your answers Domosapiens.
I am sorry that you also got problems in your installation.
What I mean is that I have only tried my two FUSensor with OpenZwave, both with a SIGMA dongle and the Razberry.

<CommandClass id="49" name="COMMAND_CLASS_SENSOR_MULTILEVEL" version="1">

</CommandClass>

This is my segment in regards to temperature. It just shows what can be seen right on the domoticz interface "164-172"c
I think I am just cursed with technology.
Thanks mate.

My problem is solved.
1 of the 4 DS18B20 sensors had a problem.
For 1 sensor there was zero Ohm between TP and TD, I think that caused a data fetch problem for all 4 sensors.
(all 3 combinations of GND, TP, TD measure infinite on my other sensors on a 200 Ohm scale)
Removal of the faulty DS18B20 did the job .... after a hard reset.
I executed the hard reset in this way:
Exclude from the dongle; power Off; push button; power On while button is pushed for 10 seconds; release button; power Off; Power on; wait a while; Include.

Elektrotek: did you executed that procedure carefully?

In the log of Domoticz, during Z-Wave start, I see that the old NodeID is removed and a new one appears.
Do you see the same?

Domoticz was not able to recognize the temp sensors within the "Allow new hardware for 5 minutes".
So I switched polling temporary On for the FGBS-001 and gave an additional "Allow new hardware for 5 minutes" and then the 3 temp sensors where there.

Your

Code: Select all

</CommandClass>
<CommandClass id="49" name="COMMAND_CLASS_SENSOR_MULTILEVEL" version="1">
<Instance index="1" endpoint="3" />
<Value type="decimal" genre="user" instance="1" index="1" label="Temperature" units="C" read_only="true" write_only="false" verify_changes="false" poll_intensity="0" min="0" max="0" value="164.00" />
</CommandClass>

looks correct (you have polling off).
The temp value in the zwcfg_0xnnnnn.xml is afaik the last measured value before Domoticz switches off (a kind of data storage) and not the actual value.
It could be the data of the last inclusion.
Is the time/date of the Temp sensor in Domoticz close to the actual time?

An other option is to remove the whole section of the FGBS-001in zwcfg_0xnnnnn.xml.
The procedure for that is: disable your Z-stick, remove the section in zwcfg_0xnnnnn.xml, save zwcfg_0xnnnnn.xml, "Allow new hardware for 5 minutes" , enable your Z-stick.

Keep on trying !

Hello,

I've the same issue. The sensor give me a crazy value (between 160 and 180 degree!). I've tried others sensors but all have the same behaviour.
How do you solve this problem ?

Thx,
Totof.

[cul8r]

Hi,

Have same problem, my sensor is giving 160-200 degree readings. (Raspberry Pi 2 / Razberry / Domoticz / openZwave / FGBS-001)

Have an idea that it could be resolution setting, 9 bit to expected 12 because reading divided by 8 would give me almost correct values.

Tested sensor by making a simple connection to GPIO9 and 1-wire support in Razbian give me correct results: see attachment

Found a suggestion on how to change resolution in this post:
https://www.raspberrypi.org/forums/view ... 37&t=77611
Tested on GPIO10 but I cannot get it to work, no response from sensor after Start-conversion-request.

Any suggestion on how to change resolution? or maybe just go out and by a new sensor

[cul8r]

I will answer myself on the temperature question:

The logs from OpenZWave show that FGBS-001 was reporting temperature and always with last byte = 0:
... Node013, Received: 0x01, 0x12, 0x00, 0x04, 0x00, 0x0d, 0x0c, 0x60, 0x0d, 0x03, 0x01, 0x31, 0x05, 0x01, 0x44, 0x00, 0x00, 0x55, 0xf0, 0x72
otherwise the hex values correspond to correct temp with resolution 9 bits (0,5 degree resolution) Tested with kernel GPIO 1-wire and readings where ok. (see previous post) Still Domoticz is showing wrong values and this happens when DS18B20 is not set to 12 bits resolution.

This is what I did to fix the problem:
My sensor, brand new from a well known store here in Sweden, was showing 160-200 degrees for room temperature 20-25 degrees C:

For a while I was thinking to make a Dummy Temp. sensor and a LUA script that divided the result by 8 and updated the Dummy sensor!

Made an DS9097E interface, dusted off an old XP, installed my old 1-wire program from 2004 (Tsa-Lämpömittari):


and changed resolution to 12 bits, now it is showing result with decimals:


Now installed sensor back in the FGBS-001 and now the values in Domoticz/OpenZWave correct!

[Totof]

Thank you cul8r for your investigation !

I have no luck ! I've buyed 5 sensors who are setted to 9 bits resolution by default ...
It will be nice if Domoticz could read correctly all sensors type.

[cul8r]

And also if Fibaro could make a change in the Config options so one could define the resolution of the temp. sensors, that would be even better!

I am leaving the FGBS-001 as a 1-wire interface, will use kernel support (w1-gpio/w1-therm modules) and with my own script to update User Variables from the temp. sensors.

I have decided to use User Variables instead of dummy temp. sensors, in this way I do not need to change the script with information of any change in Domoticz. I am not god enough to write all in python (to be able to handle decimal) so it is done in 2 scripts. It handles only DS18B20 sensors, but could easily be change to also look for other types of sensors (the prefix “28-“ says that it is a DS18B20 sensor)

To do is to check and avoid updates if values are not changed and some more error checking.

This is how to use it:
Install and make a 1-wire interface (http://www.raspberrypi-spy.co.uk/2013/0 ... er-sensor/)

Make a note of your sensors serial numbers, for ex.: 28-xxxxxxxxxxxx

For any sensor that you want the script to update, make a User Variable type Float with name = sensor serial number. For all other sensors that do not have a matching User Variable are ignored.

Place the python script in /home/pi/get-ds1820.py and make it executable:
(Can be used from command line like this: “./get-ds1820.py 28-0215618024ff”)

Code: Select all

#!/usr/bin/python

        f.close()

            print TEMP
    else:
        # print 'Missing or wrong argument of',len(sys.argv), ' arguments'
        print 999

Place the bash script in /home/pi/update-temp-var.sh, edit and change to your Domoticz server IP number and make in make it executable:
(Every time it runs it will update all User Variables with names that matches a sensor serial number and also write info into Domoticz log)

There is a way to change resolution from a Raspberry Pi! I have tested and it is working.

Found a program Raspberry forum, courtesy of Daniel Perron, modified to work on Pi2 and now I can change resolution on sensor.

Compile with
gcc -o configDS18B20 configDS18B20.c
and run it with
sudo ./configDS18B20

and you can change resolution!

It sounds great Carlos !!

Now I've to find my electronic tool box and if I've all needed resistors to connect the sensor to the Raspberry Pi.

Thank you very much.

Hi guys!
My problem with universal binary sensor and 3 DS18B20 is the teperature values:
They are all about 5-8 degrees hiyer then real ones!!!!!
Seems incredible.. so in my case the temp. 'Range' is correct (resolution is ok) but detect an offset of some degrees!!
Could be a power source problem (ripple)? I am using a 12v 500mA power supply....
I conneced temp. sensor with an audio cable (2 wire +ground wire and shielding)...
All inclusion and exclusion goes like a charm.....
I also tried to reset the UBS but nothing changed.
Help me!!!!!
