Updating Code ready for openHAB upgrade

[Taffy (Rhys)]

Good afternoon,

Im currently in the process of upgrading my openhab but need to update all my files as the last time i tried an upgrade all my mqtt items wouldn’t respond as they items files were wrong.

Ive managed to create things and items for 95% of my devices ready for the move im just struggling with this last one regarding LWT.

Could anyone point me in the right directection or have an example of how to format the thing for this device?

Switch Hallway_Fire_Alarm  "Hallway Smoke Alarm is [MAP(switchtrigger.map):%s]" <smoke> {mqtt="<[broker:tele/Hallway_Fire_Alarm/LWT:state:MAP(online.map)]"}

Thank you in advance

Does the first topic in this post help?

Control Tasmota flashed devices via MQTT

Slightly more advanced configurations This post assumes that the Things, Items and Sitemap files are already configured as in the previous post. Topics Device online/offline status The STATE message Device Wi-Fi signal quality Status on startup Device online/offline status In order to know whether our Tasmota device is actually reachable we can interrogate the Last Will and Testament (LWT) topic.

When Tasmota connects to the MQTT brok…

It does yet but I’m still confused about where I put the switchtrigger.map and the online.map?

@Taffy

put the switchtrigger.map and the online.map?

Same place as always, in the transform folder.

If you mean where in the configuration, please post the contents of both files to determine the best course of action.

[Taffy (Rhys)]

Thank you @hafniumzinc. Yes the files are already in use in the transform folder. I will reply with my configuration once I finish work today

@hafniumzinc

Ok so this is my item

Switch Hallway_Fire_Alarm  "Hallway Smoke Alarm is [MAP(switchtrigger.map):%s]" <smoke> {mqtt="<[broker:tele/Hallway_Fire_Alarm/LWT:state:MAP(online.map)]"} 

And this is my sitemap for said item

Text item=Hallway_Fire_Alarm

These are the 2 transform files

online.map
Online=ON
Offline=OFF

switchtrigger.map
OFF=Idle
ON=Triggered!
-=idle
NULL=unknown

Please could you provide info on where I should implement the online.map and switchtrigger.map in the new format.

So just to understand - you are using the ONLINE/OFFLINE status from the MQTT LWT topic to ascertain whether your fire alarm has been triggered? Does that mean when it just sits there un-activated, it is not connected to the MQTT broker, but when it senses fire it connects to the MQTT broker?

Either way, to get it working exactly the same as before:

Thing

Assuming all your MQTT Things are nested inside your MQTT Bridge/Broker Thing:

Thing topic fireAlarm "Fire Alarm" {
    Channels:
        switch : LWT "Fire Alarm LWT" [
            stateTopic = "tele/Hallway_Fire_Alarm/LWT",
            transformationPattern = "MAP:online.map"
        ]
}

or you can get rid of one of your maps:

Thing topic fireAlarm "Fire Alarm" {
    Channels:
        switch : LWT "Fire Alarm LWT" [
            stateTopic = "tele/Hallway_Fire_Alarm/LWT",
            on="Online",
            off="Offline"
        ]
}

Item

Fill in the BROKER in the Channel with your broker name, if required.

Switch Hallway_Fire_Alarm  "Hallway Smoke Alarm is [MAP(switchtrigger.map):%s]" <smoke> {channel="mqtt.topic.BROKER.fireAlarm.LWT"}

Yes I used this guide

How to add Wifi to a cheap smoke alarm

I thought I’d shared what I’ve done here with a few smoke alarms to integrate them with OpenHAB. For years I’ve had regular battery-operated smoke alarms in some rooms, but it would be nice to also get notified out of home if they were ever to go off. However I didn’t want to spend boatloads of money on funky z-wave or KNX smoke alarms, and there was no wiring or space for putting any in. Adding an ESP8266 and therefore some Wifi was the obvious temptation, but it would have drained the alarm…

Thank you I will give that a go

Yes I used this guide

Ah, I see! Makes sense now!

What’s your configuration now, and have you restarted openHAB since you’ve made the changes?

[Taffy (Rhys)]

all sorted i just added
NULL=Idle on my switchtrigger.map and its all working as it should be
