Stuck relays controlling blinds



  • Re: Stuck Relays

    I have a similar issue on my unipi neuron L203 when trying to control blinds.

    The blinds operate with 2 relays: one for up and one for down.

    The specs mention a rated current of 0.49 A, so I figured it would be fine to drive them with the built-in relays. Given I got the issue on 2 blinds shortly after each other, I'm not so sure anymore whether I can actually use them to directly drive the blinds.

    Even after powering down, I can measure (with a multimeter) that the 4 relays are still given contact -- so I'm fearing the worst, that the contacts really got stuck.

    Is there anything I can do in this situation?

    Thanks in advance



  • Replying to my own question here:

    Later in the day, after some back of forth switching of the relays I was able to get 3 of the 4 relays functioning again (the other one seems lost).

    My guess is that it's probably not ideal to use the simple built-in relays to drive the motors directly, so my current thinking is to have a look at a set of external relays to drive the motors.
