Still struggling with integrating traditional sensors into Home Assistant? Try this palm sized small module
Are you still troubled by the inability to connect the door magnets, leak detectors, and smoke alarms in your home to Home Assistant? Are you still struggling - despite having various sensors deployed at home, you can only watch them "absent" in the smart home system due to incompatible signal types?
For smart home enthusiasts,Dry contact sensorIt is the most common type of signal output - door magnetic switch, water immersion detector, emergency button, smoke alarm... These devices all output dry contact signals-However, to convert these physical signals into digital signals that Home Assistant can recognize, traditional solutions often require complex wiring, additional gateway devices, and even manual soldering of circuit boards-.
. "Every time you want to connect a new sensor, you have to tinker with wiring and code" - this is a common pain point for many HA players. Not to mention the sensors installed inside the 86 bottom box and distribution box, which have limited space and difficult wiring, making people hesitant. If there is a product that can connect any dry contact device to HA within 3 minutes, and its volume is only the size of a palm, would you be tempted?

Core Function Disassembly
Dry Contact Universal Access - All in One, Everything Can be Connected
What is the function?
HA DI01 is equipped with1-channel dry contact input channel, which supports converting the signal of any dry contact device into a digital signal recognizable by HA-Dry contact is a passive electrical switch signal - the device is either "on" or "off" and does not rely on external power supply-Almost all traditional sensors output this signal, including door magnetic switches, water immersion probes, smoke alarms, emergency buttons, and liquid level switches.
How to operate?
Simply connect the two signal wires of the dry contact device to the moduleIN end and G end(Public end), the module can automatically recognize the signal status after power on-The wiring method is extremely simple——No need for welding, no need for additional resistance, no need to configure pull-up and pull-down.
What benefits does it bring to you?
No longer have to worry about whether this sensor can be connected to HA.As long as your device outputs a dry contact signal, HA DI01 can be connectedThe old door magnets, industrial grade liquid level switches, and property installed smoke detectors in your home can all be "resurrected" and integrated into your smart home system.One module to solve the access problem of all dry contact devices.

88 port independent backend - real-time status viewing, data autonomous and controllable
What is the function?
HA DI01 has a built-in88 port independent web backend, which can view device status and configuration parameters without relying on any third-party cloud platform. The backend supports switching between Chinese and English, as well as switching between light and dark themes, and comes with built-in features?.
How to operate?
Enter the device IP address and port number (such as192.168.10.186:88) in the browser to enter the independent backend. Here you can:
-
real-time viewinput channel status(triggered/not triggered);
-
ConfigurationMQTT server connection(server address, port, username, password);
-

for you?
The data does not leave the house and is completely autonomous and controllable. Unlike some smart home devices that rely on the manufacturer's cloud platform to function, all data of HA DI01 flows locally-. You can directly collect data and monitor status through the 88 backend, or configure MQTT to push data to your own server. How to useis entirely up to you..

User verification and summary
"Previously, in order to connect an old-fashioned leakage detector to HA, I tried to write code and solder the circuit myself using ESP32, and after a whole weekend of tinkering, I still couldn't get it done. Later, HA DI01 was replaced, and from unpacking to seeing the sensor status in HA, it took less than 5 minutesLess than 5 minutes. Now all six dry contact sensors at home have been connected to HA, and the door magnetic linkage light and water immersion automatic valve closing -no longer need to get up in the middle of the night to turn off the faucet. ”Mr. Wang, a smart home enthusiast from Shenzhen
We specialize in smart home integration services. In the past, every time we installed door magnets and smoke detectors for customers to connect to HA, we had to write the configuration on site, which was time-consuming and laborious. After using HA DI01,was reduced from 2 hours to 20 minutes, and the failure rate was almost zero. Customer satisfaction and our profits have both increased. ”A smart home integrator in Shanghai, Mr. LiCustomer satisfaction and our profits have both increasedLi Gong, a smart home integrator in Shanghai
