    I’m running two OpenGarage devices, bought months apart, with identical configurations on v1.0.8 and integrated into my Homeassistant setup purely to detect car presence in a double garage.

    Configuration:
    Ceiling Mount
    Door Threshold 0
    Vehicle Threshold 150
    Read Intervals 120

    Over a period of time my first OpenGarage distance has become totally inaccurate, although the second one reports accurate distances.

    Expected readings:
    1. With car, 72-75 cm
    2. Without car, 223-225 cm

    Symptoms:
    1. Very occasional reading (without car): 450cm
    2. Very occasional reading (with car): 74cm
    3. Usual reading (approx. 80% of the time): 3-5cm

    I’ve tried to resolve this behaviour with the following checks / tests:
    1. Cleaned sensor and checked alignment.
    2. Reset configuration and re-configured
    3. Replaced USB power cable
    4. Replaced USB power supply
    5. Used a more powerful USB supply (now supplying 2.4a per port).

    I’ve also tried to re-upload the firmware via the UI, as well as downgrade via the UI – both failed.

    I’d appreciate any advice at this point.

    Now consistently reads 3-5cm.

    I’d really appreciate some advice at this point as essentially this unit (of my two) is now useless for the purpose I purchased it for.

    I suggest that you submit a support ticket to get a replacement.

    I’ve now been able to resolve the issue – the problem has not reappeared for the past 12 days after I dismantled it and refitted the case.
    I can only assume that something shifted inside the case over a period of time after originally mounting it.
