The output text is battery percentage of keyboard half with lower value. The tooltip contains battery levels of all keyboard parts.

  "custom/zmk": {
    "format": "   {}",
    "tooltip": true,
    "interval": 300,
    "exec": "ZmkBatteryClient E1:E2:69:AB:CE:90",
    "return-type": "json"
  },

• Produce waybar json output only if flag specified(--waybar)
