I guess I’m not the only one who have several battery powered led kabel / strings / and any kind of small scrap which includes led and battery.
Now I’m looking for a solution to make those things smart. I think I have to take zigbee or zwave (I personal have only zigbee) due to power consumption, but I don’t know any product.
Any hint or already deployed solution are warm welcome.
Many LED’s with battery will work with a remote that can be RF or IR.
So if you have for example a BroadLink remote you can learn and use buttons from your remote in HA script/automations.
