Entes EPM-07S multimeter

Register map(s) for this device, each at the trust rung it earned. Addresses are 0-based as on the wire. Word order and scaling are confirmed at the hardware-verified rung and at no rung below it.

interop-verified

Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.

field reports — community-sourced, unverified (checked 2026-06-11)
  • The official Entes EPM-07S manual contains a typo stating 'Energy values are sent in 64 bytes' when they are actually sent as 64-bit (8-byte) long integers. [source]
  • The official Entes Modbus register table lists continuation registers (e.g., 88, 92, 96, 100) as separate rows with blank names, which frequently leads to integration errors where developers assume 32-bit spacing instead of the actual 64-bit spacing. [source]

The trust ladder

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.

If your device isn't here, upload its register map. Generation is free, and the connector keeps the rung it earns under testing.

To prove a connector against your own device, order hardware verification. If it doesn't verify, you don't pay.

Platform builders can license the verified library: machine-readable maps, the firmware matrix, API access.
