using drivers
- HLWBL CF1
- BL0937 CF
- HLWBL SEL
CSE7766 driver of former template seems to be false
Measurements:
- DANGER: GND directly connected to Mains "L" !!!
- BL0937 Pin 6 CF (Power) connected to ESP8266Ex Pin12/GPIO13
- BL0937 Pin 7 CF1 (Current or Voltage, chosen by SEL) connected to ESP8266Ex Pin10/GPIO12
- BL0937 Pin 8 SEL not connected to ESP8266Ex (not found?)
- GPIO12 -> HLWBL CF1
- GPIO13 -> BL0937 CF
calibrated with a 75W bulb:
calibrated with an 75W bulb, data is OK, Voltage 234V Test with an other bulb (6.5W) --> Voltage 40V, Power 7W ?!? Voltage is complete nonsense.
set
- GPIO15 -> HLWBL SEL (additional for testing) Test with 6.5W bulb --> Voltage 40V, Power 2W ?!?
