DIN Rail Automation Controller - JetHome JetHub D1+

An updated model of the popular JetHome JetHub D1 controller.

The Linux controller is designed for building automation systems and monitoring: polling sensors, use as a data collection device and data transmission, execution of PLC functions in smart home systems, direct load control.

JetHub D1+ can be used as a central controller in a smart at home" together with wireless (Wi-Fi, ZigBee) and wired (RS-485) devices from other manufacturers.

Replacement of the "constructor" in the form of Raspberry PI + external devices.

Most of the interfaces required by the user are available out of the box.

The controller body is designed with the possibility of mounting on a DIN rail and allows you to conveniently place the controller in the electrical panel at home.

Motherboard revisions

• PD76-BASIC (v2) - Basic motherboard for D1+ processor module
• PD76-BASIC (v3) - Galvanically isolated RS-485 ports and dry contact inputs

Main differences from JetHub D1

• The processor is now located at the bottom, which made it possible to install a radiator on it and prevent excessive heating.
• RAM is now DDR4. Available with 2GB.
• eMMC 32GB.
• The console is output to MicroUSB on the front panel.
• MicroUSB on the front panel for flashing via Burning tool.
• LEDs have been replaced with SMD.
• Added microSD slot (currently software limitation - either SD card or WiFI works).
• Replaced Wi-Fi + BT module (it is possible to install AML W155S1 or RTL8822CS modules).

Main characteristics

• Quad-core Amlogic A113X (ARM Cortex-A53) processor with an operating frequency up to 1 GHz.
• Dual-band Wi-Fi + Bluetooth.
• Ethernet 100Mbit/s.
• Wireless module Zigbee 3.0 (optional)
• 2 RS485 interfaces compatible with modbus protocol.
• 3 relays 5A.
• 4 dry contact type inputs.
• 1 Wire interface (software, on GPIO).
• USB type A connector for connecting devices.
• The controller is powered by an external power supply 9-56v, (in kit not included), or using "Passive POE" technology via the Ethernet connector.

Peculiarities

• When connecting different power sources simultaneously, it will be from an external power supply connected to the power terminal. When one source is disconnected, the second will continue to operate.

Software

• The controller comes with pre-installed Armbian Linux operating system.
• Any other automation software can be installed on the controller, which works on Linux: Home Assistant, ioBroker, openHAB, Domoticz, MajorDomo and others.
• Documentation on installing software and using controllers is available at docs.jethome.ru

Dimensions and weight

• Dimensions: 130 x 75 x 57 mm.
• Weight: 180 g.
• Possibility of mounting to DIN rail.

Operating mode

• Working temperature: 0..+40 C.

Restrictions

• To use the device you need to have basic knowledge of Linux (ping, ssh, systemctl, ..)
• The device is not intended for video processing. Video processing may cause increased load on your processor, overheating and breakdown.
• Due to the peculiarity of the software implementation of 1 Wire in Linux, the maximum number of device sensors on one bus is 5 pcs.
