LSC smart devices

LSC smart devices flashing to work with mqtt!

Door sensors and pir, 10 euro devices

You can also flash some bulbs and LED strips, using is even easier.

@fedot Ok let me add some explanation here, the pir and door sensors are just 10 seconds connected before they go offline to save battery power, soldering is Needed to keep the esp chip online.

i had this to with the pir, seemed like there is some time delay. put the pir in a room, leave for 5 minutes and check again if you walk in.

I would just let tasmota handle a timer when the devices comes online… what can you see in mqtt broker?

Its working now , thanks
