Change color of RGB led strip over MQTT?

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

@UglyKidJoe I have been using OpenHAB and MQTT for a number of years now. The reason for using MQTT and not just a serial connection from the MySensors GW is partly the flexibility as many have stated previously here. Easy to test, using e.g. the mqtt.fx tool. If you want to know what is going on you simply connect to the MQTT stream and "snoop" on the messages. Another reason is that I am running three geographical sites on one OH installation. OH is running on a NUC at my home. There is also an MQTT GW here. Two other My Sensors MQTT-GW are running remotely in two summer houses. The three GW connect over internet to a cloud-based MQTT broker and OH connects to the same broker. In that way I do not have to open any ports into my home network for access should I have had a local MQTT-broker at home.

@Rachmat-Aditiya said: fhem is more stable but you need to configure everything manually, configure 'everything' is not entirely true, in respect to MySensors there's an autocreate-mode in FHEM. You will have to manually configure the gateway (e.g. 'define gw MYSENSOR /dev/ttyUSB0'), then activate autocreate (by pressing the include-button on the gateway, or setting the autocreate-attribute on the gateway device), then restart all MySensor-nodes and fhem will create a MYSENSORS_DEVICE-entry for every Sensor that sends presentation-messages while inclusion-mode is active.

@yoshida hi! Im not sure where you get that #9 should be A5? Looks right to me. The pin is connected to pin 9, and that is D3. For a rotary encoder, it depends on your input - but don't you want an analog signal in? In that case you use the analog pins. Edit: offcourse, if you use a module converting it to digital like described in the the build section you use a digital pin.

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.

@alexeinz figured it out, apparently had to add experimental and get latest mosquitto for the conf file to work correctly , now the bridge is working perfectly --- broker.conf file in /etc/mosquitto/conf.d the topics coming from gw will appear under sensor/# on mosquitto connection MMQTTtoSensor address 192.168.1.234 <-gw ip clientid MyMQTT cleansession true notifications true topic # in 2 sensor/ MyMQTT/
