I apologize in advance for probably asking stupid questions. I'm an experienced OS developer but this is my first foray into Groovy and Hubitat drivers.

I'm trying to create a simple virtual driver for a Notification Device. The goal is to get text notifications to go out the Maker-API and eventually into Node-Red for further processing.

Thanks to @bertabcd1234 for pointing me in the right direction to get started, I have the following skeleton driver:

metadata {
    definition (name: "Virtual Notification Device", namespace: "BKJ", author: "Bruce Jones") {
        capability "Notification"       
    }
       
   preferences {
        input(name: "logEnable", type: "bool", title: "Enable debug logging", defaultValue: true)
       input(name: "txtEnable", type: "bool", title: "Enable descriptionText logging", defaultValue: true)
   }
}

void installed() {
    log.debug "installed()"
    initialize()
}

void updated() {
    log.debug "updated()"
    initialize()
}

void initialize() {
    log.debug "initialize()"
    Integer disableTime = 1800
    if (logEnable) {
        log.debug "Debug logging will be automatically disabled in ${disableTime} seconds"
        runIn(disableTime, "debugOff")
    }
}

void debugOff() {
    log.warn "Disabling debug logging"
    device.updateSetting("logEnable", [value:"false", type:"bool"])
}

void deviceNotification(notificationText) {
    if (logEnable) log.debug "deviceNotification(notificationText = ${notificationText})"
    
    sendEvent(name: "deviceNotification", value: notificationText, isStateChange: true)
}

But when I include a virtual device using this driver as a device exposed by the Maker API, Maker API doesn't see any events from this device.

What needs to be done in a driver for the Maker API to process the device's events? sendEvent() alone doesn't seem to be enough.

Bruce,
Your device itself has the method deviceNotification, but there is no code in this driver to test if the notification is working. For test purposes create a command "test" that calls the new method test. Test would then call deviceNotification.
