EasySensors “6Gang30AmpsLatchRelayEspHomeReady” (now that’s a product name!) is a DIN Rail mountable, ESP32-S2-based automation device featuring six 32A latch relays and supporting ESPHome open-source framework.
The system also comes with two inputs for Dallas temperature sensors, two buttons for manual control of relays, a USB-C port for programming, as well as an external SMA antenna for WiFi connectivity.

The ESP32-S2 firmware’s binary files are available on Github, and the instructions to get started with ESPHome can be found on Github.io. Note this requires Google Chrome or Microsoft Edge, and Firefox does not work. You can check out how to get started in the video below.
Considering the device is supposed to handle up to 32A and connect to the mains, I was quite surprised the company did not provide any information about safety, either through specific measures taken during PCB design or safety certifications like TUV or ETL.
EasySensors ESP32-S2 6-gang home automation solution can be purchased on Aliexpress for $74 plus shipping. Note it’s not the first time we write about EasySensors, as the company’s easySwitchBox LoRa wall switch was featured on CNX Software when it launched on Crowd Supply in 2019.
