Seeking clarification on preferences{} and actual device params

I’m using it in the updated() event.

Thanks for the info! I think this confirms what I was thinking, updateSetting may only work when it’s used based on a user making changes in settings. I’m going to check if there’s any way to establish a session based on what the error is saying, but I’m not too sure it’s possible. Might be a security thing to prevent settings randomly changing on a user.

This is how I use updateSetting and deleteSetting in smartapp.

github.com

hongtat/tasmota-connect/blob/master/smartapps/hongtat/tasmota-connect.src/tasmota-connect.groovy#L553-L574


def deleteChildSetting(id, name=null) {
    // If a name is given, delete the K/V
    if (id && name) {
        if (settings?.containsKey("dev:${id}:${name}" as String)) {
            app?.deleteSetting("dev:${id}:${name}" as String)
        }
    } else if (id && name==null) {
        // otherwise, delete everything
        ["ip", "username", "password", "bridge", "command_on", "command_off", "track_state", "payload_on", "payload_off", "command_open", "command_close", "command_pause", "payload_open", "payload_close", "payload_pause"].each { n ->
            app?.deleteSetting("dev:${id}:${n}" as String)
        }
        // button
        for(def n : 1..6) {
            app?.deleteSetting("dev:${id}:button_${n}" as String)
        }
    }
}


def settingUpdate(name, value, type=null) {
    if(name && type) { app?.updateSetting("$name", [type: "$type", value: value]) }
