Changing units of Voltage Measurement Tile

Hi J,

The "units" parameter in SmartThings Events isn't used consistently by Device Type Handlers, so ActionTiles must ignore it.

You can change your DTH to make a more meaningful claim of Capability "Battery" instead of Voltage Measurement. Battery reports a single integer attribute "battery" of value 0 to 100 (representing percent). http://docs.smartthings.com/en/latest/capabilities-reference.html#battery

The ActionTiles "Battery Tile" will then be applicable to show your Water Tank level...

Make sense?

...Terry.

Thank you for your reply however I am not having much success with this as I am using ST_Anything for my sensors and so it is not as straight forward as I hoped. I have been able to change the Capability to 'Battery' but am not being able to get the values through.

If you have the time would you be able to show me what I need to change in Dan's code to get it to show as a battery in ActionTiles?

Mostly you just need to change "Voltage Measurement" to "Battery" and "voltage" to "battery"; but that doesn't cover the parse() method.

The parse() method is grabbing the keyword "voltage" (I think?) from the message from the device, and using that to set the name.

So my untested guess as to the code:

metadata {
    definition (name: "Child Voltage Sensor", namespace: "ogiewon", author: "Daniel Ogorchock") {
        capability "Battery"
        capability "Sensor"
        attribute "lastUpdated", "String"
    }
        
    tiles(scale: 2) {
        multiAttributeTile(name: "battery", type: "generic", width: 6, height: 4, canChangeIcon: true) {
            tileAttribute("device.battery", key: "PRIMARY_CONTROL") {
                attributeState("battery", label: '${currentValue}%', unit: "%", defaultState: true)
            }
             tileAttribute("device.lastUpdated", key: "SECONDARY_CONTROL") {
                    attributeState("default", label:'    Last updated ${currentValue}',icon: "st.Health & Wellness.health9")
            }
        }
    }
}
def parse(String description) {
    log.debug "parse(${description}) called"
    def parts = description.split(" ")
    def name  = parts.length>0?parts[0].trim():null
    def value = parts.length>1?parts[1].trim():null
    if (name && value) {
        // Update device
        if ( name == "voltage" ) { name = "battery" }
        sendEvent(name: name, value: value)
        // Update lastUpdated date and time
        def nowDay = new Date().format("MMM dd", location.timeZone)
        def nowTime = new Date().format("h:mm a", location.timeZone)
        sendEvent(name: "lastUpdated", value: nowDay + " at " + nowTime, displayed: false)
    }
    else {
        log.debug "Missing either name or value.  Cannot parse!"
    }
}

If this doesn't work, you can contact us for paid screen sharing session(s) to test & debug with your actual physical device and/or ask Dan (the original DTH coder) for assistance ... and donate to him accordingly.
