    Switch and Sensor seem to not work when cold

    I'm not sure of the exact model, i will need to look at the device to determine that, it's some version of MS-OPS, just a sensor and switch, no dimmer functionality.

    Most mornings the light will not turn on, neither the sensor nor the push button switch will cause it to come on. I live in california, and it does not reach freezing temps where I live but it can get down in to the 40's or 50's in my garage over night.

    Has anyone else had this issue?

    Thank you for reaching out. The normal operating temp range is from 32F-104F and recommended for indoor use only. If the temperature has dipped in the space, it could have an effect on functionality.

    Here is a link to a spec sheet for the MS-OPS line of products:
