Hello Romain, Laurent
Looks really cool what your trying to achieve, I think addressing this at a fundamental level would be to to include your input and work in the ARM SystemARCH group and SystemReady programs. As this is working with the actual device vendors and manufactures, e.g OEMs' ODM's It steer's what data we expect out of ACPI for example. USB-PD started to put pressure too on this topic. like CPE's, POE based devices and more carrier gear you see in the TN stacks at Telco's
I work with ARM, i;m in the technical committee for both groups above. A large majority of network gear is built on, as energy and performance is key driver for them. Just reach out directly to me
btw.. two challenges with your setup: in-line power is physically difficult, most network gear has two circults, two PSU's, and current goes up to 16A access to PDU data will give you mA over SNMP, but mostly in management networks

Dear all,
My name is Romain; I’m a researcher at ETH Zürich working with Laurent Vanbever. I have led projects on sustainable networking for about 2+ years now.
One important challenge the academic community currently faces is the lack of quality data for the energy a router or switch consumes. To address this, we work on fine-grained power modeling of network devices, and we need data to validate their accuracy “in the wild.” To facilitate that, we worked to realize the vision of “RIPE Atlas for power data” I pitched at last winter’s RIPE meetinghttps://ripe87.ripe.net/archives/video/1143/. And I’m happy to say that we are ready to start distributing measurement units!
Concretely, we are looking for people willing to
* Install measurement units in series of each PSU of routers and switches. The measurement unit is an MCP39F511Nhttps://www.microchip.com/en-us/development-tool/ADM00706 power meter combined with a Raspberry Pi for management and data collection:
[cid:part1.Gh4kAtHz.OQ00ccNf@ethz.ch]
We will provide the appropriate cabling. To control the unit, the Pi needs to be connected to a publicly reachable network via RJ45 (WiFi connectivity is technically possible as well, but requires additional setup)
* Share device-specific data with us, including at minima
* Packet and/or byte counters for the active device interfaces. * Types and numbers of transceivers plugged in.
and optionally
* PSU-internal measurements * Operating system version * Fan speeds * CPU load * Average room temperature conditions * Let the measurement run for at least one week.
* Send us back the measurement units (we provide pre-labeled packaging for that).
In return, we can only offer our sincere gratitude and the guarantee that your effort will contribute to the progress of science! I know it s not much, but I hope that’s worth something :-)
➡️ If you are interested, please let me know by replying to this email. Thank you in advance!
Note: We want to publish the collected data (in an anonymized way), but that is optional. If you are willing to contribute but your organization opposes the data sharing, we won’t publish it, and we will sign NDAs if necessary.
Thank you again for reading! Looking forward to hearing from you,
