Calibration problem (<4w consumption)

Morning#Glitter#8474

Hi all, I have just installed my shelly 2.5 as roller shutter following the guide here:

https://shelly-forum.com/lexikon/index.…zmD0r7gKlF4LC7g

Shelly configured as roller shutter mode and when testing the power consumption "1. First check if the power consumption works correct" the app reports a less than 1W consumption as per attachment.

Performed a twice reset and also factory reset, no changes... calibration cannot be com

What can I do next?

Thanks in advance.

Hi @Stexxe , welcome to the forum.

Officially, this will not work due to the low load.

What you can try is:

Measure the travel times

Connect 2 light bulbs to the shelly to simulate the engine.

You start the calibration and switch off the corresponding lamp when the previously measured runtime has been reached.
When the second lamp lights up, switch the first on again and vice versa until the calibration has been completed.

Then you connect the roller shutter again.

Good luck.

Hi,

I have the same 4W problem as my shuther is contrable through both a telecontroller and a pushbutton and therefore has a low voltage receiver.

Firstly, I tried the light bulbs trick but was having problems with it (don't know why). Then I realized that I have another shutter with the same size as the problematic one (same travel times) but without the telecontroller low voltage receiver so I connected Shelly to this one to calibrate it.

I suceeded on it and the shutter started to show the positioning bar, but when I put my Shelly 2.5 again in the problematic one, it wasn't able to position the shutter in the position I want. For instance, If the shutter is up, and I put it at 50%, it starts goind down and suddenly the cursor goes to 0% and the shutter closes completely. Same doing the opposite from down to up not being able to stay at the position I want.

I was wondering if it needs more than 4W power not only in the calibration process, but also during its regular working.

Thanks in advance.

Hi Antonio, welcome to the forum.

Do you have activated security features (obstacle detection, ...) ?

If yes, you can try without this functions.

Thanks 66er for your quick response.

Obstacles detection is disabled and security interruptor is disabled by default as I don't use a single button input.

I just have enabled max power protection at 1840W. I've just checked to disable it and it's still happening the same, it just ignored the position that I want and keeps progressing to the end (and the position marker in the app too, going from 100% to 0% no matter what I choose).

Don't have a clue on what to do.. to be honest..

Thanks

Antonio
