1. Version History

2. Overview

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

Device Info:

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

3. Configuring Profiles

Familiarize yourself with the display.

3.1. Step 1: Mioty DEVEUI

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

3.2. Step 2: Navigate to Mioty Payload Profile

Use the down arrow key to navigate to "Mioty Payload Profile Settings." The number at the bottom indicates the selected payload profile.

3.3. Step 3: Changing the Profile

Using an insulated screwdriver, press the button on the lower right, as shown in the image. The number will then be displayed as a 3-digit value, e.g., 001. Use the right button to navigate through the decimal places, and the down button to adjust the respective digit (increment).

In the following image, 004 has been set.

3.4. Step 4: Confirm the profile

To change the profile, please press and hold the button on the back right with an insulated pin or screwdriver until the display and keypad flash briefly.

5. Naming Conventions

• Voltage: u_lX (phase/line)
• Current: i_lX (phase/total)
• Power: p_lX_a (active, phase/total)
• Energy: e_t{a|1|2}_{a|r}_{i|e} (e.g., e_ta_a_i)
• Power Factor: pf_lX
• Frequency: f
• Transformer ratio: {ct|vt}_{act|old}_{prim|sec}

7. Factory Setting

Profile 0 is used as the factory setting (see 8).

8. Profiles

8.1. Profile 0 – Complete data

Comprehensive measurement values: power, current, voltage, energy, power quality.

• Power (W): p_l1_a, p_l2_a, p_l3_a, p_l123_a
• Current (mA): i_l1, i_l2, i_l3, i_l123
• Voltage (V ÷10): u_l1, u_l2, u_l3, u_l12, u_l23, u_l31
• Energy (Wh): e_ta_a_i, e_ta_a_e, e_ta_r_i, e_ta_r_e
• Power Quality: pf_l1–3 (÷100), f (Hz ÷10)
• Status: pwr_fail

8.2. Profile 1 – Voltage & Current

Focus on voltage and current values with power quality.

• Voltage (V ÷10): u_l1, u_l2, u_l3, u_l12, u_l23, u_l31
• Current (mA): i_l1, i_l2, i_l3, i_l123
• Power Quality: pf_l1–3 (÷100), f (Hz ÷10)

8.3. Profile 2 – Power & Current

Focus on active power, currents, and power quality.

• Power (W): p_l1_a, p_l2_a, p_l3_a, p_l123_a
• Current (mA): i_l1, i_l2, i_l3, i_l123
• Power Quality: pf_l1–3 (÷100), f (Hz ÷10)

8.4. Profile 3 – Energy Meter

Minimal payload for billing & monitoring.

• Energy (Wh):
  • e_ta_a_i, e_ta_a_e
  • e_ta_r_i, e_ta_r_e

8.5. Profile 4 – Historical Data

Extended profile, including timestamps, rates, and CT/VT configuration (Little-Endian).

• Time/Index: index, epoch, epoch_old
• Energy by rate (Wh):
  • T1: e_t1_a_i/e, e_t1_r_i/e
  • T2: e_t2_a_i/e, e_t2_r_i/e
• Currents (mA): i_l1–4, i_l123
• Power (W): p_l1_a, p_l2_a, p_l3_a, p_l123_a, p_l123_a_avg
• Voltage (V ÷10): u_l1, u_l2, u_l3
• Power Quality: f (Hz ÷10), pf_l1–3 (÷10)
• CT/VT configuration: ct_act_prim/sec, ct_old_prim/sec, vt_act_prim/sec, vt_old_prim/sec

9. Data Encoding

10. Usage Notes

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;

11. Compatibility and Notes

• Firmware version 1.3 or higher required
• Payload only if fw_minor_ver ≥ 3 and status = 0
• All fields are visible; no hidden fields
• Ensure correct endianness
• Optimize profiles Payload size depending on use case
• Profile 4 enables time series analysis with epoch timestamps
