Gate sensors does not work when raining

[JamieF]

Hi,
Are you referring to the receiver end of your photocells? If so, the rain could be obstructing the photocell beam. Especially if the beam isn't very strong, due to being at its max range - rain could cause intermittence in the beam. I would recommend the following below.

- Check the alignment of the cells
- Check the max range of the cells
- Check that the cells have not been damaged internally by water ingress

I would not replace a kit just yet, especially when it is just a photocell fault showing. Firstly, i would fault find the cells - a replacement pair of cells may possibly be needed.
