+# Homie-RCWL #
+
+## RCWL-0516 radar occupancy sensor with esp-01s. Using MQTT with homie convention to transmit data.
+
+## Notes ##
+
+* using RX pin on ESP-01s as GPIO0 and GPIO2 seem to cause boot issues because of internal pull up resistors.
+* The 3v3 output pin on the RCWL does not supply sufficient current to power ESP-01s
+* RCWL is 5v powered
