Logistics - Akash will make a new email series, including Jude. Agendas will be sent 24 hrs in advance over email.
Whatsapp: - OpenAMI Coms Integration → Inhemeter
Tech Comm and OpenAMI → used for presentations
ISV AMI Subcommittee
Arila is not on Whatsapp
Ask Rajan if he wants the weekly emails 1) Any updates from the crowd – Donsun, Sparkmeter, EarthSpark current state Rahul + Daniel - SparkMeter has been “handed over” to EarthSpark after SparkMeter collapsed. Allison is the president of EarthSpark. She makes the call if/when SparkMeter becomes Open-Sourced. Vivien is the guy leading the open-source effort. Sparkmeter's operating costs are artificially very high. Sparkmeter wraps the cailin's hardware in their own protocol. Worldbank M300 → project from World Bank for electricity reach 300Mill new people in africa Things we need How we're doing vending
Correct timestamps
Information about the grid Proposed solution: take the telemetry from the field, add an additional service (?) and have access to the data via the server infrastructure 4 organizational members: IEEE, EnAccess, NESL, Arila Rahul proposal:
Open AMI server, standardize schema (glenn has started this), called Grid Fabric. Linux foundation project. Not the Hyphae project. * This project takes the logs from the DCU
MicroPowerManager needs a plugin to ingest this data.
Grid Fabric supports 2 protocols, both can be run on DCU * DLMS → MQTT → Vendors are offering the keys to these protocols, not hacking the solutions * Donsun, StemaCo, Inhemeter (not explicitly yet)
Donsun - has offered access to DCU (serial console / Telnet). Busybox linux environment. They have spare CPU cycles we can run other processes in. * The guy who offered the keys is now gone though, and said Donsun is bankrupt
We weren't talking to Donsun directly though.
“Leets” from Donsun
Jude has Nigeran Donsun hardware
StemaCo - service provider * Donsun is one of 6 chinese OEMs that StemaCo will support
If we go through StemaCo – EnAccess - any updates/questions/agenda topics? – Sparkmeter source code access? — Rahul/Enaccess currently have it – Akash-plan/idea to hack the SparkMeter from Sun Gate Solar Rahul has access to code base, but it's “a mess” Jude:
We thought we had commitments to get keys to access hardware. * Inhemeter is now asking for a contract
Sparkmeter - stuck asking Alison (EarthSpark) trying to get opensource access 1 month later * There may be some Google Drive with limited access to see source We Cannot use anything from this drive, legally, without Open-Sourcing it
Rahul - we have pretty good reference of the architecture, but legally we cannot use it till Alison approves. * TAM (AMDA): 1M meters, $20/meter = $20M TAM
Seems unlikely we'll get access for free
Donsun - collapsed mid-conversation
StemaCo - we will probably hit the same wall As of today, we have no keys to any hardware. Only open hardware is our own board. 2) Clarification of problem statements, both short-term and long-term. – Short term will include exit of major metering vendors – Long term will include discussion of software and hardware solutions – We can use the Cairo OpenAMI slide deck ( link ) to start the discussion.
Don - are we trying to hack existing systems or use the OpenAMI as our own standard?
Last meeting, we found all the OEMs are having the same vulnerability. Don't want to support legacy products of theirs. Question: Should we have this be a software-only solution? – Jude, Akash 3) Hardware discussion – Utility and desires for the MeshEMS gateway – Arila, Jude, Glenn, Akash, Rahul – What if we made our own hardware?
2 major players have already failed
Rajan is skeptical
Vivian - thumbs up. Not for the meters, but maybe for the DCU.
Jude - yes let's talk about this * Lots of donor money available
Roadblocks - local developers/infrastructure
Stemaco, Sparkmeter → were all whitelabeling a few OEMs. Did not make their own hardware (both metering and DCU).
Sparkmeter - was whitelabeling their own meters, but making their own DCUs.
Jude's idea: * AMDA developers have 3 priorities: * Vending
Monitoring ability
Ability to do operations (on/off control)
Vending: * Solved by STS/OpenPay Go
So long as you have the CIU (customer intefface) at the meter level, and the token generation software, you can vend irrespective of the (?)
Monitoring and Operations * This is not yet solved. What if we take this as a standard?
Like STS, we build a comms standard that can be deployed by the OEMs for people that want to go beyond vending.
Maybe this requires an open-source DCU to go with it
Building software that can go on DCUs that lets the data seen in multiple places
Similar to an STS certification, this could be a selling point for new developers to use OEMS that are “OpenAMI” compliant OpenPay Go and STS - similar For talking to the edge meter (supports STS, version 2)
You'd need a key that talks to the STS 4) Blockers / goals for setting up Yaounde lab with Glenn's VPN hardware – Glenn, Jude, Endurance 5) ISV Funding and Project Plan Revisions – Don, Rajan, Jude
Adam- how can we live stream any existing data from villages?
October 15th, 2025:
0) Recap of Oct 8th meeting for folks traveling back from Power Africa (Arila or Daniel)? (5-10 mins)
Nothing major to discuss 1) Akash/Jude: Power Africa Recap (5-10 mins) a. Presentation recap
Discussed with minigrid developers
Sun Moksha - Indian minigrid company that is building smart metering. 3 priorities * Vending - ability to make sales
Manage the energy / assets
Monitoring - what sparkmeter can provide
Sun Moksha agrees on scarcity of metering suppliers / availability
They have a prototype working on this that has solved their problem
Make their own controller that talks between the meters (modbus) and server (wifi mesh), which then talks to the cloud
They are open to share IP with the IEEE community; they've invested a lot of $ and don't have too much incentive to provide
Not open-sourcing, but some sort of license that gives other vendors
They built their own proprietary hardware (with ESP32 equivalent) that they could sell b. Discussion recap / feedback session
Jude: This looks like another locked solution, we would have the risk of being stuck on them
Arila: Is there any openness from the open-source perspective from SunMoksha? * Jude: This was developed for India, they had a sponsored project from India. Was a larger for minigrid developers in India previously, but currently isn't such a big market
Arila: Is there an open solution available on the cloud side?
Akash: * Mou Riiny - interested in OpenAMI, frustrated with Sparkmeter
Shared a sparkmeter to debug (malfunctional)
Sparkmeter * Vivien/Jude might have access to their repos
What's the goal with this one? * Just a test bed for now
Akash to share
Jude may have functional sparkmeters * Nova / Edge Meter
Has some spares c. Akash - will try to make a slide on this 2) Jude: Client/customer's wishlist (5-10 mins) a. Jude's thoughts on the current status of the project b. Include pivots of the direction he would like to take this 3) Inhemeter call - Jude/Michel/Akash (5 mins) a. Recap of call with Sanji from inhemeter They want a signed document before providing documentation Awaiting on the confidential agreement from Inhemeter <→ Michel F is working on this b. “Cannot support the Inhe-4000 you got from nigeria” Latest model available is the Inhemeter-5000 c. “Please give us your specs for a new order” Donsun - sales person is no longer at Donsun Donsun is now bankrupt (!) Purchased sample meters through StemaCo Rahul - Sparkmeter Sparkmeter has custom radios, not modbus 485 Need to be on their custom neighborhood network Rahul has access to the codebase and developers → can share answers to the queries Dominant architecture in Africa Radios are working on a certain set of frequencies, these are pretty locked Seems very hard to jailbreak existing sparkmeters based on this Recommends avoid committing to jailbreaking this Maybe easier to do if we are already in contact/customers with them Arila: Was under the impression that there is Modbus Donsun Splitting into 2 One for Africa One for rest of world? Could expect code stubs for AMI potentially Rahul → older conversations \\ 4) Formal roles within volunteer team - Jude a. Product Manager b. Project Manager c. Administrators d. Other roles? 5) Auditing/Changing of project timeline - Akash in place of Don (cannot make it) 6) Techincal debug and setup of REI-Cameroon Lab - Glenn/Endurance/Rahul a. Summarizing status of remote access b. Setup of new hardware / VPN from Glenn Looking forward:
So many meter vendors going bankrupt or not helpful
How do we salvage existing meters/hardware in the field from these bankruptcies? * Specific to REI-Cameroon, * Jude has Sparkmeter and Stemaco (using Donsun) * Sparkmeter has also moved to stop usage of older hardware
Currently has ~800 sparkmeters
Other hardware is at risk too
Rahul: * Would be great if we can support legacy systems. Some vendors (Sparkmeter for example) are not open to being supported
While providing this legacy support, we basically create the support/framework for OpenAMI Vivien:
Sparkmeter has not yet committed to becoming open, but needs help (has a lot of tickets, backlog, etc). Sparkmeter
Allison is the person we need to convince
Rajan has talked, Vivien has talked to them, Jude has also talked to them, AMDA has also talked to them
M300 has given them $ to stay alive, we have about 3-6 months of funding there What do we as OpenAMI focus on in the next 3-6 months?
Rahul: Support on legacy solutions
Jude: Re-formulate the implementation plan * Seems like everyone will be legacy soon
Go back to drawing board
Open-Source Hardware?
Arila: * Open-source meter for EnAccess
Yes - but not available for use though
For next week: * Come with proposals for OpenAMI
Akash - hardware gateway prototype * No progress to report
Is anyone blocked by this yet?
Could be useful for some hardware prototyping
Glenn's hardware *
Endurance hasn't been able
Follow-ups
- Rahul weekly meeting?
Stemaco and Donsun relationship?
Vivian hardware access?
Sparkmeter source code access?
