Making your RF 433mhz sensors and devices communicate with your home automation, gateways comparison
After more than one year of usage of home automation (HA) I have seen that one critical point is the communication between the sensors/devices and the HA system. There is several possibilities for that: Infrared 5,8ghz 2,4ghz 867mhz 433mhz wire ... And for each of these possibility we can have a huge amount of different protocols. The goal of this article is to draft a list of the 433mhz gateways that can be found. We will focus on 433mhz due to the fact that i n european countries 433mhz devices/sensors are quite easy to find and with a correct price. We will take the following citerias: Price DIY complexity Number of protocols taken into account Complexity of home automation integration And take a look at RFXCom, RFLink, 433toMQTTto433 ESP8266, 433Utils, Broadlink RM... I will put in green the keypoints of each gateway. E&R = 433mhz emitter and receiver, can be a FS1000A and a XD-RF-5V or a superheterodyne one (recommended)
