  • Manages a high capacity (30A at 120/240VAC) load, ideal for pool pumps or water heaters
  • Available as Normally Open or Normally Closed (select option prior to adding to cart)
  • Approved for indoor or outdoor installations (NEMA 4X enclosure)
  • Energy metering measures instantaneous (kW) and lifetime (kWh) energy consumption of loads
  • Also acts as ZigBee router/ range extender providing increased stability and coverage for your network
  • Smartenit app accessible
  • 1 year Smartenit warranty


ZBMLCSR is a wireless, high capacity, load controller that tracks its loads’ power consumption and offers remote control for ultimate ease of use.

When used within a ZigBee HA system managed by one of our Harmony gateways, ZBMLCSR is accessible through our mobile app.  You will be able to clearly see power consumption data, have on/off control of the connected load, and include the ZBMLCSR in automation events or schedules all from the convenience of your smart phone. As part of a larger ecosystem, you can turn off loads in response to energy thresholds, set usage windows, and have loads respond to external sensor data.  Joining an HA network is easy and once achieved, ZBMLCSR also acts as a router, boosting your network’s coverage and stability.
