+## Ghost Switching
+Some of these devices are prone to hardware ghost switching. You may need to experiment with `ButtonDebounce` and `SetOption40` to reduce or eliminate these issues.  
+
+Also, during the flashing process, you may have soldered a lead to GPIO0 in order to connect it to GND for putting the ESP into programming mode. If there are any random oscillations on GPIO0, this can trigger the relay. The contacts on the PCB are very close together. Check that you don't have any stray solder to another contact. Even if there isn't contact, over time heat and humidity can cause any residual flux to become resistive and allow conductivity. Be sure to clean everything after removing any leads.

 ## Known so far
 * When pushing a button, the touch chip lift the power high to the EFM8BB1, and the EFM8BB1 chip ties the signal line for each button low, for the full duration of the keypress. Debouncing is not needed.
 * 433MHz remotes are compatible with the Tasmota firmware
