Fibaro Roller shutter FGRM-222 calibration solution
« on: August 14, 2016, 04:18:41 pm »
Configuration and calibration Fibaro Roller Shutter module FGRM-222.

Hi All,

First I had many problems to calibrate the module. Percentage didn?t work.
The FGRM-222 needs to be a calibration process first.

The module needs a minimum ballast of 1W or more (230V screen motor with end switches)
If you use  a relay on the outputs, the calibration didn?t work.

I have a solution for this:

First 1 connect a toggle switch(1 - 0 - 2)on the outputs Q1 and Q2  from the FGRM-222.
1 to output Q1, 2 to output Q2 and the P (middle contact) connect to a 230V/20W bulb, other site of the bulb connect to N.
If I put the switch on 1 and connect S1 to L the bulb is on. Put the switch on 2 the bulb is on if I connect S2 to L

With a stopwatch I measuring the time that the screen needs to be go up and down. (For me 40s up and 40s down).

Set the switch to position2
Now I start the calibration function (Zwave options  variable 29>1 didn?t work fine for me) so I use the manual option: Connect S1 3x fast to L, 3xfast to L, 3x fast to L and the calibration function will start
The bulb go on.
Start the stopwatch and put the switch in position 1 after the time is expire that the screen needs to be go up.
Now put the switch in position 2 after the time is expire that the screen needs to be go down.
After  these process the FGRM-222  calibration is almost completed.

NOW FIRST: go to your device option of the FGRM-222 in the vera. (Devices>FGRM-222>Device Options)

Set the variable 18 to 0 and save this. You can check this if you select back and select device options for the 2 time. Now you will see the current value. If it?s ok? it?s 0. If it is 1 or more it is not ok? and you will be need to store the variable for the 2 time.
If it is be 0 the calibration process is completed  and the FGRM-222 is ready for use. Percentage will work fine now.

Thank you very much for this.  My roller shutter module wouldn't calibrate either. I could use the Vera to initiate the calibration process, but as soon as the curtains got to one end, it would just stop and the module would blink red, instead of moving back in the opposite direction.

I hooked up a light in parallel with the motor, so that I didn't have to worry about timing it. I just flicked the attached light with a toggle switch when the curtains got to one end, and hey presto, the curtains moved back in the opposite direction like they should, and the percentage now has shown up in the UI properly.  Before doing this, if you clicked on anything in between 0 and 100%, the curtains would automatically open or close entirely; there was no in between.

I think there is still something dodgy about the Watts being reported, as it seems to be constantly on 1 Watt, but that doesn't really matter.

This was in conjunction with a DOOYA DT82TV motor.  I think perhaps the electronic limiting of the motor interferes with the calibration process as it slows down automatically, and is not relying on the Z-Wave module to find, and set the limits.

I found a setting which helps this combination of module, ( Fibaro Roller Shutter 2 - FGR-222 v2.5 ) and motor.  Parameter 22 sets the time out of the motor which is necessary because otherwise the Z-Wave module keeps powering the motor, even after it has reached the end.

It doesn't matter because the motor has its own limit switch, but if you press the button on the wall, then you need to press it twice, (once to stop the Fibaro from still keeping the motor running, and then again to do what you want).  By timing, (in my case the curtains fully opening, or closing takes ~12 seconds), I set the motor to run for a maximum of 15 seconds, as per the picture below.

Now it works with just one press, no matter if it was operated with Z-Wave via Alexa, PC, tablet, etc. or the physical switch.

The other way to avoid the problem would be to set scene activation on, (parameter 50 to 1) and monitor when you get a single keypress, and run a scene that opens, or closes.

For some reason I can't turn on scene activation on one of my Fibaro modules, even thoough it accepts the parameter.  Weird: one does, one doesn't.  You need to press the physical button and scene activation variables then show up.

I could not calibrate this motor Dt88TV with Fibaro and I have changed all the motors with DT82TS and everything is perfect now the procentage works fine: I can close 20% or 75% or 100%.
