Change color of RGB led strip over MQTT?

augusthalverson last edited by

I was wondering how you change the color of RGB LED strips over MQTT with a raspberry pi gateway. Thanks in advance

Hi and welcome to the MySensors community @augusthalverson !

In general, you just set the color in your controller. It works the same way regardless of which type of gateway you are using, so there is nothing specific about mqtt.

You might be able to get some inspiration from https://forum.mysensors.org/topic/4934/wall-mounted-mood-light-v2

I really don't think this is a sitemap issue. I don't know the language well enough to speak of this but the error I am getting is [ERROR] [o.u.i.items.ItemUIRegistryImpl:411 ] - Cannot retrieve item 'itm_office_mqtt_motion_switch' for widget org.openhab.model.sitemap.Switch This makes me think it is an item issue not a sitemap issue. I captured this startup information from the log file: [DEBUG] [.b.mqtt.internal.MqttActivator:34 ] - MQTT binding has been started. [DEBUG] [i.internal.GenericItemProvider:334 ] - Start processing binding configuration of Item 'itm_office_mqtt_string (Type=NumberItem, State=Uninitialized)' with 'MqttGenericBindingProvider' reader. [DEBUG] [b.mqtt.internal.MqttItemConfig:71 ] - Loaded MQTT config for item 'itm_office_mqtt_string' : 1 subscribers, 0 publishers [DEBUG] [o.i.t.m.i.MqttBrokerConnection:476 ] - Starting message consumer for broker 'officepi' on topic 'office_string' [DEBUG] [m.internal.MqttEventBusBinding:61 ] - MQTT: Activating event bus binding. It shows the process for binding the itm_office_mqtt_string Item, but there is no mention of the binding of the itm_office_mqtt_motion_switch Item. Should there be? If so, anyone know why it might not be there? As I said above, when I comment out the itm_office_mqtt_string Item in the items file, OpenHab refreshes (see below) and allows the itm_office_mqtt_motion_switch Switch Item to function. [INFO ] [c.internal.ModelRepositoryImpl:97 ] - Refreshing model 'mini.items' [DEBUG] [i.internal.GenericItemProvider:154 ] - Processing binding configs for items from model 'mini.items' [DEBUG] [m.i.MqttGenericBindingProvider:73 ] - Removing message consumers for item itm_office_mqtt_string [DEBUG] [o.i.t.m.i.MqttBrokerConnection:505 ] - Unsubscribing message consumer for topic 'office_string' from broker 'officepi' [DEBUG] [m.i.MqttGenericBindingProvider:106 ] - Removing message publishers for item itm_office_mqtt_string [DEBUG] [b.mqtt.internal.MqttItemConfig:71 ] - Loaded MQTT config for item 'itm_office_mqtt_motion_switch' : 1 subscribers, 0 publishers [DEBUG] [o.i.t.m.i.MqttBrokerConnection:476 ] - Starting message consumer for broker 'officepi' on topic 'office_motion' [DEBUG] [i.internal.GenericItemProvider:133 ] - Read items from model 'mini.items' The sitemap works when the item can be retrieved, but I don't know why only one item is being retrieved, not both.

By creating the file org.eclipse.smarthome.mqttbroker.cfg in the service folder (/usr/local/etc/openhab2/services in my case, chown to openhab), with the contents name=mosquitto host=192.168.1.69 secure=false port=1883 username= password= retain=true I was able to just create the MySensors MQTT gateway (using paperui) and it stayed online (no mqtt broker defined, but its addon is installed). I had the impressions that with the latest versions it should be possible to do everything in the PaperUI, and that the broker would use the mqtt2 addon (but in paper ui, service, config, mqtt tab, mqtt system broker connection, manage->plus button -> expert mode, I get to see the contents of the cfg file above) But unfortunately, it seems that the discovery services enters a endless loop (maybe I need to update my arduinos sketch to the latest mysensors code?) and I don't get any auto discovered things. If I trigger a new discovery it will stop the previous one and start again. Finally, I was able to manually create a thing, and link items on it. Eventually my battery level and humidity were displayed in the paper ui control page (after some weird delay, not updating once it shows in the log. the temperature didn't show up though). Not sure if my understanding is off (or paperui is limited in this sense) but in the "thing" creation page I only get to specify one child id. Then my multi sensors/value nodes would need to be define in multiple things? As I can't properly define channels for each child id, and I'm not sure what var1-5 are all about. I'll try defining things/channels/items directly in files in the following days, because so far I couldn't enjoy most of the benefits of this new version (auto discovery, logical grouping of physical device in "things", questionable "do-it-all in paper ui"), and I'm almost considering using mqtt1 binding in the new install

@Jan-Gatzke said: Did you install the exec addon? Thank you Sir! was asking in a different forum as well, nobody had the idea to install this binding first and I didn´t know a binding is needed for execution of commands... Well then, problem solved

@AWI @Hoffan @sundberg84 I can see both sketches are working, this is what the gateway prints out: 0;0;3;0;14;Gateway startup complete. 0;0;3;0;9;read: 105-105-0 s=255,c=0,t=18,pt=0,l=5:1.5.1 105;255;0;0;18;1.5.1 0;0;3;0;9;read: 105-105-0 s=255,c=3,t=6,pt=1,l=1:0 105;255;3;0;6;0 0;0;3;0;9;read: 105-105-0 s=255,c=3,t=11,pt=0,l=5:Relay 105;255;3;0;11;Relay 0;0;3;0;9;read: 105-105-0 s=255,c=3,t=12,pt=0,l=3:1.0 105;255;3;0;12;1.0 0;0;3;0;9;read: 105-105-0 s=1,c=0,t=3,pt=0,l=0: 105;1;0;0;3; 0;0;3;0;9;read: 105-105-0 s=2,c=0,t=3,pt=0,l=0: 105;2;0;0;3; 0;0;3;0;9;read: 105-105-0 s=3,c=0,t=3,pt=0,l=0: 105;3;0;0;3; 0;0;3;0;9;read: 105-105-0 s=4,c=0,t=3,pt=0,l=0: 105;4;0;0;3; Is this correct?

I'd say it is the same but it would you will need to do more coding I guess. There is a node-red Google group if you want to ask there also.
