Battery Moving Sensor

Hi, I have installed a garden light from Govee what is integrated in my WLAN. I would turn on the light if someone is in my garden. I hope the only thing I need is a moving sensor. But here starts my problem because I don’t know which outdoor battery moving sensor I should use. Do you have any recommendation?

Solution 1 would be to search for tasmota/esphome motion sensor outdoor.
Solution 2 would be to search for zigbee motion sensor outdoor (additionally take a look at zigbee2mqtt’s supported devices. I found the Luminea ZX-5311 which could fit for you).
Solution 3 would be a camera with motion and night vision functionality, which works with home assistant like Reolink. That way you can also monitor your garden.

It depends if you can get power/PoE to the location. 1 and 3 use more energy than 2 but you dont need to set up a zigbee network.
