With mqttlink you can trigger mqtt messages with a redstone signal

tested with Version 1.9.3

• /mqttlink [topic] [on message] ([off message])
  • Will always link the focused block
• /mqttdel [id]
• /mqttedit [id] [key] [value]
• /mqttlist

• topic - mqtt topic
• up - on mqtt message content
• down - off mqtt message content
• t - material
