Communication with External Devices

When you connect a smart meter, smart plug, or other device to the micro-storage system, the system will automatically communicate with it to collect power consumption or generation data.

• Local communication (LAN): used for real-time data acquisition (fast response)
• Cloud communication (remote): used for App display and historical data logging

Communication methods vary slightly across different brands, but the system automatically adapts—no manual configuration is required.

Brand	Local Communication	Cloud Communication
Shelly	HTTP	Routed via Micro-Storage
Ecotracker	HTTP	Routed via Micro-Storage
Stromleser	HTTP	Routed via Micro-Storage
HomeWizard	HTTP	Routed via Micro-Storage
SOLARMAN	UDP broadcast	Direct-to-Cloud
INDEVOLT	Private protocol	Routed via Micro-Storage

tip

“Routed via Micro-Storage” means data is first sent to the micro-storage system and then uploaded to the cloud in a unified way.

1. Local Communication

Local communication is used to obtain real-time device data. Update frequency may vary depending on the device.

info

The device data refresh rate adjustment feature is not yet available. It will be added in a future App update.

1.1 HTTP Communication Devices

Data is obtained via local LAN HTTP interfaces, offering stable performance.

• Default update interval: 2 seconds

• Adjustable range:

  • SolidFlex 2000 / PowerFlex 2000: ≥ 1 second
  • BK1600 / BK1600 Ultra: ≥ 2 seconds

• Supported devices

P1 meter reader	P1-2W P1-2W-C	500 ms	≥150 ms
Smart plug	SP-2W-EU	500 ms	≥150 ms

note

The following device is under integration and will be supported in a future release:

• P1-2WR

1.3 INDEVOLT Devices

Communication is based on a proprietary private protocol developed by micro-storage.

• Default update interval: 2 seconds

• Adjustable range: ≥ 1 second

• Supported devices

  Type	Model
  Single-phase meter	SMD1
  Three-phase meter	SMD3
  Smart plug	SP16

2. Cloud Communication

Cloud data is used for remote access, such as viewing device status or historical records in the App.

All devices follow the same rules:

• Default update interval: 300 seconds (5 minutes)
• Fast refresh mode enabled: 1 second refresh
