Hyperion Mioty Profile  

Firmware and Data Profile Reference for Hyperion Energy Meter

📄 You can view the PDF above or download it here .

Overview 

The Hyperion Energy Meter (Sentinum) transmits energy data via the MIOTY protocol. This document describes the payload structure, profiles, and field definitions (from firmware v1.3 onwards).

Device info:

  • Type EUI: FCA84A0000000006
  • Vendor: Sentinum
  • Protocol: mioty
  • Firmware: v1.3+ (payload only for fw_minor_ver ≥ 3 and status = 0)

Setting Profiles 

Profile Setting/Value
0 0
1 001
2 002
3 003
4 004

Familiarize yourself with the display

Step 1: Mioty DEVEUI

Use the down arrow key to scroll down to the "Mioty DevEUI Settings" section as shown on the screen. Here you will see the device number.

Step 2: Navigate to Mioty Payload profile 

Use the down arrow key to navigate to "Mioty Payload Profile Settings."

The number below indicates the set payload profile.

Step 3: change the profile 

Use an insulated screwdriver to press the button on the bottom right, as shown in the image. The number will then be displayed as 3 digits, in this case 001. Use the button on the right to navigate through the decimal places, and the button on the bottom to manipulate (increase) the respective place.

 
Note: The profile must always be specified in the following format: 001 or 004, etc. Even if the meter setting for a code of 009 is possible, for example, this is not a valid profile. A 0 can be reached again by counting up to 9, after which the digit jumps back to 0. Please set the profiles 000 to 004.

In the following image, 004 has been set 

Step 4: Confirm profile 

 
Note: To change the profile, press and hold the button on the rear right with an insulated pen or screwdriver until the display and keypad flash briefly.

Power 32b int 1:1 W
Energy 64b uint 1:1 Wh
Power Factor 8b int ÷100 (÷10 for LE) –

Usage Instructions 

Profile selection:

  • Profile 0 = Full monitoring
  • Profile 1 = Voltage quality
  • Profile 2 = Power analysis
  • Profile 3 = Billing
  • Profile 4 = Historical data

Example .js:

const voltage = raw_u_l1 / 10;  // 2350 → 235.0 V
const pf = raw_pf_l1 / 100;     // -85 → -0.85
const net_energy = e_ta_a_i - e_ta_a_e;
const ct_ratio = ct_act_prim / ct_act_sec;

Compatibility

  • Firmware ≥1.3 required
  • Payload only with fw_minor_ver ≥ 3 and status = 0
  • All fields are visible, no hidden fields
  • Observe endianness correctly
  • Optimize profiles — Payload size depending on use case
  • Profile 4 enables time series analyses with epoch timestamps
