Review

Hands-on Street-EMS / MeshEMS for in-country engineers on village mini-grids. Compare commercial AMI (SteamaCo, SparkMeter) with open OpenAMI cabinets. MQTT as the common bus. See OpenAMI · OBIS · VMRS · roadmap.

Code challenges (tracks that opened)

Opened Monday 16:15. Teams pick one primary track; wrap-up Thursday. Hardware + firmware paths: Street-EMS / MeshEMS and meshems-openami-metering ↗.

#	Track	Goal	Done looks like
1	SparkNet → MeshEMS / OpenAMI	What SparkNet-HTTP can usefully feed into MeshEMS OpenAMI metering — without pretending SparkNet RF meters are DLMS.	REST/SSE → MQTT (or OpenAMI northbound) bridge sketch. Document limits (proprietary field radio vs open HES).
2	DLMS/COSEM-friendly “hello world”	Smallest credible energy telemetry on Street-EMS + CircuitSetup 6-port ATM90E32 energy-cache path in `meshems-openami-metering`.	OBIS-shaped (or clearly mapped) P / V / I / energy on MQTT; note true DLMS vs CircuitSetup cache.
3	Intelligent LV feeder add-on	Choose one: continuous neutral-balance recovery or leakage detection.	Edge alert or actuation before a street-cabinet safety breaker trips. LCOE vs opex one-pager.
4	15-minute PCB smoke test	Bring-up one Street-EMS PCB. Pass/fail once.	On-board LEDs + MQTT topic (identity + pass/fail + short diagnostic).
5	Calibration testhead + QR “smart start”	3-phase PSU PCB + Street-EMS calibrated together. Unique QR. Factory file host still TBD.	Scan pair → pull cal record. Foreshadow installer/repair app on an LV feeder pole.
6	Village Simulator · microgrid O&M UX	BUILD mode + OPERATIONS / MAINTENANCE — not another pretty dashboard.	Concrete UX delta an operator would use after the change.

Shared wrap-up axes (all tracks)

Open MeshEMS/OpenAMI vs proprietary full-stack on cost · lock-in · sovereignty · comms · repair. Optional stretch: prepaid mobile-money token path if a team had bandwidth after the primary track.

Village Simulator — BUILD

Workshop progress on the Village Simulator (code track 6): BUILD mode — microgrid developers construct the system. Constructed data auto-formats to the Open Utility Network convention (not a standard — see Village GeoJSON). Layers in play: LOADS and GENERATION (Energy Assets). Main view splits OPERATIONS and MAINTENANCE. Live app: overview-solutions.github.io/smart-village-simulator ↗ (new tab if the wiki frame is blank).

Interest forms stay off this repo (no emails copied here). Name list from the sheet is pending — public CSV/HTML fetch failed without a Google login.

PCB interest sheet ↗ More interest form ↗ Code Challenge sign-up (wiki form)

Handwritten handout list TBD

Who received NESL 865B / cabinet kits on paper is not transcribed yet. Empty until organizers type that list. Do not treat the Google sheet as proof of boards handed over.

Personas

Stylized figure at a laptop with a notebook and small project board — **Students** use the system for a project

Stylized figure at a scale fork between a small cluster of houses and a larger cluster — **Founders** considering whether they can scale with this kind of system

Stylized figure holding a clipboard beside stacked study notes and a chart — **Researchers** assist in conducting research studies

Follow-up — next few weeks

Transcribe the handwritten PCB / cabinet handout list onto this page (names + org only if the person already signed the public interest sheet).
Work the PCB interest sheet and the more-interest form — no emails published here.
Keep simulator BUILD → Open Utility Network convention (LOADS · GENERATION) and the OPERATIONS / MAINTENANCE split.
Carry MeshEMS / OpenAMI thread into the OMS Workshop Nairobi (30 Sep–2 Oct) and OSEAS Kigali (26–27 Oct).
AMDA outreach still open: #14.

Kits

Brought for take-home: NESL 865B MeshEMS v2.0 (15–20 PCBs planned), 3–5 TC2.0 cabinets, DLMS meters, CircuitSetup 6-port expansion meters, 100A CTs. BOM / firmware: MeshEMS hub · meshems-openami-metering ↗. Who walked out with which board: handwritten handout list TBD.

Came away with

Workshop left initial use-cases / starter projects to learn the system.

Starter projects

Line drawing of a house with a lamp, outlet, and small energy monitor — **Smart Home project**

Line drawing of a solar array and battery with a clamp-on monitor on the cable, no revenue meter — **Monitor for non-metered energy system**

Line drawing of three-phase bus bars, a DIN-rail controller, and a circuit monitor — **Industrial circuit monitor/controller**

Training

People at the workshop asked for a training session on OpenAMI EMS, the Village Simulator, and the workshop stack. ISV will run a training session in a few weeks. No date, venue, or sign-up on this wiki. Separate catalog of work that needs training (OMS pre-session interest + this ask): OMS / village training skills — catalog only, modules TBD.
