The house is a valuable asset that needs to be guarded, not infrequently some people experience undesirable things happening in the home environment, these things include fires and theft. Anticipation is not just enough by manually such as locking the door, or preparing fire extinguishers, in addition to the manual way of anticipation can be added by automation, namely by installing devices that can monitor the condition of the house and also can control electrical equipment in the house. The automation tool intended in this study is an IoT-Based Smart Home Controller Using the NodeMCU Lua V3 Microcontroller and Telegram Chatting Application. The use of automation systems like this is an option to be implemented because it saves power and the price is relatively cheap. This device / system uses 2 NodeMCU Lua V3 microcontrollers and several sensors (fire sensors, motion sensors, temperature and humidity sensors) and also this role utilizes the 4 Chanel Relay Module which functions as a switch to turn off or turn on electrical equipment in the home. The control function of the smart home controller device also utilizes the Telegram chat application bot that is planted on an IoT-based system device with the function of receiving commands from users through the Telegram chat application to monitor the condition of the house and also controls the relay module used as a switch of equipment.
