    Hello.
    I have been playing around with HA for about a month now. I purchased on aliexpress a microwave presence sensor (zigbee) powered by USB (5V about 150mA).
    What 5V/2A power supply (charger) do you recommend for 24/7 operation, I would need a few pieces. I found somewhere on the internet that someone recommended chargers from IKEA. Maybe chargers (branded) for phones (just how to be sure if not fake)? Any other suggestions?

    Any 5V 1A charger from a phone. You can buy for nothing, e.g. Apple original with usb.

    I am not concerned with the parameters but with the model that colleagues have been using for a long time in their smart home.
    Requirements:
    1. to not have a gratis fire (design faults of the power supply, no short circuit protection)
    2. to ensure that the power supply does not emit too much interference (no filters on the primary side) "to the socket" but also to the sensor being powered.

    Because of these 2 points, I reject power supplies/chargers from aliexpress (well, unless someone can recommend a proven model).
    I am wondering about chargers from IKEA (rather they should not sell lime) - maybe someone uses(s)?
