ChgInd: Charge State Indicator¶
Control three LEDs to indicate charging & SOC level
Version 1.0 by Michael Balzer <email@example.com>
Following an idea by “green_fox” on the german Twizy forum (not limited to the Twizy) to implement an externally visible charge indicator.
Use a red, a green and a blue LED to signal charge state:
- OFF = not charging
- RED = charging, SOC below 20%
- YELLOW (RED+GREEN) = charging, SOC 20% … 80%
- GREEN = charging, SOC above 80%
- BLUE = fully charged (held for 15 minutes)
This plugin uses three EGPIO lines to control the three LEDs (KISS). By using a shift register this could be reduced to two lines, by using a serial protocol to one line. The latter would need protocol support in the EGPIO (todo).
Add line to
chgind = require("lib/chgind");
script reloador evaluate the
// EGPIO ports to use: const LED_red = 4; // EIO_3 const LED_green = 5; // EIO_4 const LED_blue = 6; // EIO_5 // Time to hold BLUE state after charge stop: const holdTimeMinutes = 15;
chgind.set(state) -- set LED state ('off'/'red'/'yellow'/'green'/'blue')
