### Sagewood   


Sagewood is a UK based logistics supplier. +44 7831 135528 - Manoj

Got some feedback on this one . Here goes… Hi Hilary, all good am still in china snd heading back tomrrow to uk. China was on national holidays from 30 April to today May 5. Now working on it. I have discussed with the team - Due to small number of meters for the system, we suggest a cloud version so you don’t have to invest in hardware. Many endusers are doing this. Meters we can handle but MOQ is around 2000 metres. Or we can manufacture them to very with other orders. So you don’t have to worry about MOQ. Allow me few days and I revert back.

#### Recommended for Residential Microgrid Applications in Uganda:

- **LoRaWAN**: If covering a large geographical area (kilometers), due to its excellent range, penetration, and low power use.
- **Wi-SUN**: For robust, medium-to-large-scale smart metering networks, especially if a mesh topology is desirable.
- **Zigbee/Thread**: Ideal for dense residential areas where devices (meters) are closer together, benefiting from low power and reliable mesh networking.

#### Recommended Wired Protocols for Residential Microgrid Metering (Uganda)

- **PLC-based (e.g., G3-PLC or IEEE 1901.2)**:
    
    
    - Ideal due to existing infrastructure (power lines).
    - Good for scalable, reliable deployments.
- **RS-485**:
    
    
    - Robust, simple wiring suitable for smaller clusters.
    - Common for direct-wired connections (local clusters).
- **M-Bus**:
    
    
    - Suitable if integrating gas, water, or heat metering alongside electricity

### 💡 Recommended Choice: Hybrid or G3-PLC

#### 📌 Primary Recommendation: G3-PLC (Wired)

Given your scenario (dense apartment blocks with existing electrical infrastructure and meters located closely on the ground floor), **G3-PLC** offers significant advantages:

- **Low Ongoing Maintenance:** No batteries to manage.
- **High Reliability:** Stable signal leveraging existing wiring.
- **Cost-effective (long-term):** Minimal ongoing costs after initial installation.
- **Robust &amp; secure**: Highly suited for apartment complexes.

#### 📌 Alternate Recommendation: Hybrid (PLC Backbone + Wireless Endpoints)

If flexibility or future expansions matter, consider a hybrid setup:

- Use **G3-PLC** within each block to connect meters reliably to a local gateway.
- Connect block gateways to a central system via wireless (**Wi-SUN or LoRaWAN**). This reduces physical disruption between buildings while maintaining the reliability within each block.

This hybrid method provides the best of both worlds—flexibility and low maintenance.

### Examples

#### Example #1

You query the meter for meter operating status and you get back this

[![Screenshot 2025-09-04 at 14.21.36.png](https://bookstack.nearlyfreeenergy.com/uploads/images/gallery/2025-09/scaled-1680-/screenshot-2025-09-04-at-14-21-36.png)](https://bookstack.nearlyfreeenergy.com/uploads/images/gallery/2025-09/screenshot-2025-09-04-at-14-21-36.png)

#### Answer 

**Meter operating status = 1008**

**Step 1: Interpret the Code**

- In many AMI/CalinMeter integrations, codes like <span class="s1">**1000**</span> and <span class="s1">**1008**</span> map directly to <span class="s1">**relay/disconnect statuses (Code 87 sub-codes)**</span>.
- **1008 = Sub-code 8 under Code 87**<span class="s1">.</span>
- From the guide:
    
    
    - <span class="s1">**8 → “Not-active”**</span> → *Meter not commissioned*.

**Step 2: What This Means in Postpaid Setup**

- The meter is physically installed, but it hasn’t been <span class="s1">**commissioned**</span>.
- In this state, the meter will <span class="s1">**not supply power**</span>, regardless of load or tariff configuration.

**Step 3: Field Action (from Quick Action Guide)**

- <span class="s1">**Action**</span>: Commission the meter using the <span class="s1">**commissioning token/code**</span>.
    
    
    - Default commissioning code is <span class="s1">**12345**</span>.
    - Enter this via the CIU (Customer Interface Unit) or backend if supported.
- Once successfully commissioned:
    
    
    - Tamper detection is activated.
    - Relay will close and supply will start flowing.

<span class="s3">✅ </span>**Summary:**

<span class="s3">Your AMI response of </span>**1008**<span class="s3"> means </span>**“Meter not commissioned.”**

👉 To resolve: Enter <span class="s1">**12345**</span> (or your site-specific commissioning token) on the CIU/backend to activate the meter.

#### Example #2 

[![Screenshot 2025-09-04 at 14.36.50.png](https://bookstack.nearlyfreeenergy.com/uploads/images/gallery/2025-09/scaled-1680-/screenshot-2025-09-04-at-14-36-50.png)](https://bookstack.nearlyfreeenergy.com/uploads/images/gallery/2025-09/screenshot-2025-09-04-at-14-36-50.png)

#### Answer

Great — let’s now map <span class="s1">**1000**</span> through the same guide.

Case: Meter operating status = 1000

**Step 1: Interpret the Code**

- In the AMI integration, <span class="s1">**1000**</span> corresponds to <span class="s1">**Code 87 sub-code 00**</span>.
- **00 → “Relay Closed”**<span class="s1">.</span>

**Step 2: What This Means in Postpaid Setup**

- <span class="s1">The meter is </span>**active and commissioned**<span class="s1">.</span>
- The <span class="s1">**relay is closed**</span>, meaning the meter is supplying electricity normally.
- No tamper or abnormal condition is blocking supply.

**Step 3: Field Action (from Quick Action Guide)**

- <span class="s1">**Action**</span>: No intervention needed.
- Record this status if troubleshooting, since it confirms the meter is healthy and delivering power.

<span class="s3">✅ </span>**Summary for your case:**

<span class="s3">Your AMI response of </span>**1000**<span class="s3"> means </span>**“Relay Closed – supply ON.”**

👉 Everything is normal; no technician action required.

⚡ So together:

- **1000 = Relay Closed (meter supplying power)**
- **1008 = Not-active (meter not commissioned; activate with commissioning code)**
