use sensor battery status to give to homekit

[tvillingett]

From the API

The battery status is now also included in the sensor/info and sensors/list API call. Possible values are:
0-100 - percentage left, if the sensor reports this
253 - battery ok
254 - battery status unknown (not reported by this sensor type, or not decoded)
255 - battery low

with no batteryinfo:
{"id":"9044149","name":"Garage inne","lastUpdated":1478118807,"ignored":0,"client":"130828","clientName":"Torodd1","online":"1","editable":1,"battery":254,"keepHistory":0,"protocol":"fineoffset","model":"temperaturehumidity","sensorId":"231"}

with battery OK
{"id":"7877912","name":"Utetemp norrsida","lastUpdated":1478118860,"ignored":0,"client":"130828","clientName":"Torodd1","online":"1","editable":1,"battery":253,"keepHistory":0,"protocol":"oregon","model":"EA4C","sensorId":"130"},

in homekit set StatusLowBattery = 0

and with "battery":255

set StatusLowBattery = 1

Otherwise with 0-100 % use set low battery at maybe 5% ?
(because the temperaturesensor in homekit don't support percentage, only ok or low battery)

I have no sensor device to test with and I don't know the format of the getSensorInfo response so I wouldn't know how to implement that, although it should be quite simple yes:

something along the lines:

            if (cx instanceof Characteristic.BatteryLevel) {
                cx.on('get', (callback) => {
                    TelldusLive.getSensorInfo(this.device, (err, device) => {
                        if (err) return callback(err);
                        const val = device.DONTKNOWWHATSHERE;
                        // TODO TRANSFORM VALUE TO 0-100
                        this.log("Battery sensor " + device.name + " [" + val + "]");
                        callback(false, val);
                    });
                });
            }
