MQTT buffer length is limited and SENSOR message will be truncated above 18 DS18x20. Even less if other sensors are attached to the ESP device and present in the SENSOR message. 1-wire has been designed to be a board-bus, not to run through long distances across a whole house. At minimum, use a shielded cable. Note. If you increase the value above default, you are on your own. No support will.

Therefore, by using MQTT you can establish communication between multiple devices. Using MQTT you can send a command with a client to control output or you can read data from a sensor and publish it to a client. There are two main terms in MQTT i.e. Client and Broker. Let's discuss what actually a MQTT client and MQTT broker is: MQTT Client: An MQTT client runs a MQTT library and connects to.

What makes MQTT faster than say sending HTTP requests with your IoT device is MQTT messages can be as small as 2 bytes, whereas HTTP requires headers which contains a lot of information that other devices might not care about. Also, if you have multiple devices waiting for a request with HTTP, you'll need to send a POST action to each client. With MQTT, when a server receives information. I have an ESP-01 that I want to measure pool temperature with. It will send the data over MQTT to the broker. I have connected RST to GPIO16 so I can use the deep sleep functionality. Currently I a
