Wireless 8-Relay / 6-In Input Output Controller


IoT8-Z – Model # 3012A Input Output Controller

IoT8-Z provides on/off control of small to medium sized electrical loads (lighting, irrigation, garage door openers, HVAC dampers, alarms, etc.) through 8 separate Form-C relays.  Additionally,  4 digital and 2 analog inputs enable monitoring of external electrical signals such as switch closures, analog sensors, digital sensors, motion detectors, liquid sensors, etc.  The device mix of inputs and outputs enable many applications that combine sensors and actuators in the most flexible and efficient way.

Smart Possibilities:

  • Control irrigation and outdoor lighting from one compact controller to implement the perfect smart yard
  • Automate water circulation pumps and lighting in a pond
  • Automate water system in a rural residence (well pump, resorvoir tank, booster pump)
  • Use ZigBee or Insteon keypads or switches to control multiple “non-smart” devices
  • Sound an alert or chime when your garage door is opened and operate doors remotely.


  • Eight general purpose, Form-C relays rated 3A @120VAC/24VDC
  • Four opto-isolated digital inputs (logic high: 3-30VDC)
  • Two inputs configurable as digital (0-1VDC for OFF, 2-2.4VDC for ON) or analog (10 bit resolution)
  • Compatible with ZigBee 3.0 and HA profile
  • Available with LoRa protocol (select option in menu)
  • Compatible with Insteon networks (requires a Smartenit ZBPLM).
    • Acts as an Insteon sender with each of the inputs able to trigger a unique group on/off command
    • Responds to Insteon (direct or group) commands to turn on or off each of the 8 outputs
    • Extensive command set for maximum programming flexibility
  • 1 year Smartenit warranty


IoT8-Z is a combined input and output controller, that allows sensing incoming signals from up to 6 wired sensors (analog and digital) as well as controlling up to 8 small to medium sized devices.  This puts input/output control at the point of need, eliminating wiring nightmares.  IoT8-Z allows the use of simple and cost-effective sensors such as magnetic door contacts and analog temperature sensors.  The many combinations of sensors and actuators allow an abundance of solutions in homes, buildings, factories, farms, etc.

NOTE: The included 12VDC power adapter is required to operate the device. To purchase additional adapters click here.

For Insteon connectivity, purchase a compatible ZBPLM (Mfg Date 1/20/2018 or later).

Outputs EZIO2X4 IoT8-Z IoT4R
Supported Protocols Insteon & X10 ZigBee, WiFi, LoRa & Insteon Insteon, X10 and WiFi
Controls Each output can be linked to an Insteon group to be controlled by an Insteon scene controller (Ex. Keypadlinc, Switchlinc, etc.)
INSTEON ‘All-Link’ A snapshot of the outputs can be recalled with a single group command (i.e. respond to a switch or a button on a Keypadlinc, ControlLinc, etc.)
Timers Timers from 1 second to 255 minutes can be set up to turn off each output
# of Outputs 2 8 4
Types Relays (normally open) Relays (both normally open and normally closed provided) Relays (both normally open and normally closed provided)
Ratings 30VDC/120VAC, 0.5A 24VDC/120VAC, 3A 30VDC/120VAC, 0.5A
Output Uses General purpose contact closures of small loads limited by relay voltage and current rating. General purpose contact closure of larger loads limited by relay voltage and current rating. General purpose contact closures of small loads limited by relay voltage and current rating.
Inputs EZIO2X4 IoT8-Z IoT4R
Controls For the digital (opto isolated) inputs, each input is ON when when current flows through the input or OFF when current is absent. Changes from OFF to ON and from ON to OFF can be used to control other ZigBee or Insteon devices. For analog inputs, voltage levels translate to points and On/Off transitions can be regulated by programmable trip points thresholds.
Timers Delayed OFF commands (from 1 to 255 minutes) programmable on each input. This timer resets (starts over) if a new ON command is received.
# of Inputs 4 6 None
Inputs Type 2 Opto-isolated (3-30VDC), 2 digital or analog (0-5VDC) 4 Opto-isolated (3-30VDC), 2 digital or analog (0-3VDC) N/A
