Hi everyone,

I’m part of an early-stage team working on an AI energy product for California homes with rooftop solar, batteries, and EVs. We’re software-first today, but we’re evaluating whether adding a small CT-based in-home electricity monitoring device is technically and commercially justified, or whether it would introduce too much hardware, installation, and certification complexity too early.

The engineering decision we’re trying to sanity-check is this:

Should a software-first energy product add its own home energy monitoring hardware, or rely on existing inverter / battery / EVSE APIs and third-party monitoring devices until the product is more mature?

The areas we’re trying to understand are:

1. Smart metering / energy monitoring hardware:

smart meters, submeters, CT-based energy monitors, metrology ICs, AFE design, firmware, calibration, ODM manufacturing, electrical safety, and US certification. Especially helpful perspectives would include engineers who have worked on firmware or AFE/metrology for companies such as Itron, Landis+Gyr, Honeywell Smart Energy, EDMI, or similar smart metering companies.

2. Smart home / IoT protocols:

Matter, Wi-Fi devices, MQTT, local APIs, Home Assistant integrations, cloud-vs-local architecture, and connected energy devices.

3. DER / inverter / battery / EVSE API integrations:

the current practical API landscape for ecosystems such as Tesla and Enphase, including data availability, granularity, reliability, permission limits, and whether those APIs can replace or partially replace our own monitoring hardware.

Specific engineering questions:

- For a CT-based home energy monitor, what are the main technical risks around measurement accuracy, phase identification, calibration drift, installation variability, safety, and connectivity?

- If using an ODM, what engineering constraints tend to be locked in early: metrology IC choice, CT selection, enclosure, installation method, firmware architecture, calibration process, or certification path?

- At early production volumes, what BOM drivers usually dominate for a simple but reliable monitoring device?

- For a US launch, which certification paths tend to matter in practice for this type of product, such as UL 2808, UL 916, FCC Part 15B/C, or other standards depending on architecture?

- From a smart home integration perspective, how important are local access, MQTT, Matter support, open APIs, and avoiding cloud-only data?

- For Tesla, Enphase, or similar DER ecosystems, what data is realistically accessible today through APIs, and what are the limitations around real-time access, permissions, reliability, and long-term maintainability?

- If designing from scratch, would you start with Wi-Fi + local/cloud API first and add Matter later, or design around Matter compatibility from day one?

- What are the common engineering mistakes software-first teams make when they add electrical monitoring hardware too early?

This is not a product promotion or a hiring post. I’m trying to understand the engineering tradeoffs before we make an architecture decision.

If anyone with direct smart metering, CT-monitoring, certification, Matter / Home Assistant integration, or Tesla / Enphase API integration experience is open to a short expert interview, please email tvd55085@gmail.com with a brief note on your background. For safety, we’ll only coordinate through that email and won’t respond to unsolicited DMs.

Thanks in advance.

Hi everyone,

I’m part of an early-stage team building an AI energy product for California homes with rooftop solar, batteries, and EVs. We’re software-first today, but we’re trying to decide whether it makes sense to add a small in-home device for household electricity monitoring.

Before we go too far down the hardware path, I’m trying to sanity-check the real-world productization side with people who have actually worked on smart meters, submeters, CT-based energy monitors, or similar connected electrical devices.

The questions I’m trying to understand are pretty concrete:

• If this type of product goes through an ODM path, what would a realistic minimum MOQ look like?
• For a simple but reliable home energy monitoring device, what BOM range should we expect at early production volumes?
• For a US launch, which certifications are likely to matter in practice? For example, UL 2808, UL 916, FCC Part 15B/C, or other standards depending on the architecture.
• Are there any common mistakes software-first teams make when they try to add metering hardware too early?

I’m not trying to promote a product here. We’re still at the decision stage and trying to learn from people who have been closer to hardware, manufacturing, or certification than we have.

If you’ve worked on smart metering, energy monitoring, ODM manufacturing, or certification for connected electrical devices, I’d really appreciate your perspective. Also happy to learn what kind of expert we should be looking for if this becomes a deeper workstream.

Thanks in advance.
