They work nicely with my zigbee2mqtt setup. They are DJT11LM, which integrates nicely with home assistant. I have one usecase where I will use one on the washingmachine to be notified when it is finished. But I have not tried that yet. Very fast delivery.
Not as discribed, the sensor not working and not detected the vibration or movements, so not recommended if someone he want using it as security. Or for any other purpose The seller is not answer I raised the dispute for refund. Seller not cooperative to solve the issue.
