Internal hardware analysis of the EP40 reveals high-quality Songle relays and a MediaTek or Espressif chipset, depending on the revision. The unit features an IP64-rated chassis assembled via ultrasonic welding to maintain resistance against dust and water ingress. The dual-outlet design allows for independent control logic, with a total load capacity of 15A.
Performance metrics demonstrate that the external-facing antenna design facilitates 2.4GHz penetration through exterior wall structures. While the device lacks internal hardware for energy monitoring, it provides local API accessibility for stable, non-cloud dependent operation.
- Independent addressing for both power sockets.
- Local control via Python-based protocols to reduce cloud reliance.
- Reinforced strain relief for improved structural durability.
Operational insights recommend vertical mounting to prevent water wicking through the power cable. The unit is not rated for submersion or standing water.
If your technical requirements include tracking electrical costs, the WiFi Smart Outdoor Plug with Energy Monitoring provides the necessary shunt resistor hardware.
This switching node is classified under the smart power hardware group.
