Hello Erik, Thanks for your quick reply. I use the right UID instead XYZ (EJi) I think it's not a quoting issue because when I don't put correct quotes, I get: {"_ERROR": "Could not parse payload for write_frame call of dmx_bricklet EJi as JSON: Extra data: line 1 column 4 (char 3)"} I also have a Segment Display 4x7 Bricklet and use similar synthax for function "set_numeric_value" and it work well. My MQTT bindings version is tinkerforge_mqtt 2.0.15 I try other function like "get_dmx_mode", "read_frame", "set_dmx_mode" and "get_dmx_mode". It work perfectly. Here is output of "get_identity": {"uid": "EJi", "connected_uid": "Lnk", "position": "a", "hardware_version": [1, 0, 0], "firmware_version": [2, 0, 3], "device_identifier": "dmx_bricklet", "_display_name": "DMX Bricklet"} Thanks for your help Jérémie

Hello there, I am working with bricklet DMX. I need to use it as DMX mode master and MQTT API. Unfortunately, when I publish on topic "tinkerforge/request/dmx_bricklet/XYZ/write_frame" a message with value "'{"frame": [255,128,0]}' " I get message "_ERROR": "required argument is not an integer (call of write_frame of dmx_bricklet XYZ)" on topic "tinkerforge/response/dmx_bricklet/XYZ/write_frame" It work perfectly with Brick Viewer. My setup: Hardware: DMX Bricklet with FW 2.0.3 on HAT Brick FW 2.0.2 MQTT brocker: mosquitto version 1.6.10 MQTT Client: MQTT-Explorer 0.4.0-beta Do you know if do something wrong? or if is it a bug? Thanks in advance for any help. Jérémie
