The gigantic and unregulated power plants in the cloud

Grid security and national vulnerability

• Many argue that cloud-controlled inverters, heat pumps, home batteries and EV chargers create a new “soft” critical infrastructure layer that can be centrally misused or hacked, especially when vendors are foreign.
• Concern that Chinese vendors or their government could deliberately disrupt European grids in a limited conflict, without it being “total war.”
• Others counter that major grids already have many ways to be disrupted; focusing on one cloud vector may overstate its marginal impact compared to physical attacks on transformers or control rooms.
• Discussion references lab work (e.g., Aurora generator test) showing small control changes can physically damage large equipment, but some professionals say protections and layered relays make “blow up the grid via PV” scenarios unrealistic.

Centralized cloud control vs local control

• Vendors route monitoring and control through their own clouds because consumers/installer lack networking skills, support must “just work,” and devices often have tiny local storage.
• Critics note cloud could instead be a dumb relay for end-to-end encrypted local protocols; current designs give vendors full remote control and firmware update paths.
• Several users describe running systems fully offline or LAN-only (e.g., via MQTT, Modbus, Home Assistant, RS232), but this requires expertise and is not mainstream.
• Some products support both cloud and local paths; others make local control difficult or require physical hacks (e.g., removing Wi‑Fi modules).

Decentralization promise vs new chokepoints

• Solar and other distributed renewables were expected to decentralize power; central fleet control via vendor clouds reintroduces choke points analogous to big web/cloud platforms.
• Commenters connect this to broader trends: always-connected cars, bank APIs gated by web UIs, and “you’ll own nothing” device models where the vendor retains real control.

Regulation, responsibility, and safety

• Debate over where to regulate: edge devices (inverters), their cloud platforms, or grid interconnection points.
• Some call for bans or strong limits on remote control and firmware updates; others stress that certification, paperwork and fines can turn into compliance theater without real competence.
• Professionals point out that rooftop PV is generally treated as non-firm and excluded from critical load-flow planning, limiting its systemic impact, but others note that aggregate instantaneous PV power in places like the Netherlands is now comparable to dozens of reactors, making coordinated outages a serious stability risk.

Usability vs security in IoT

• Thread repeatedly returns to the tradeoff: society consistently chooses convenience over secure-by-default local control.
• Proposals include better local-network tooling, IPv6 with static addresses, standardized “cloud-free” options, and clearer, furniture-manual-style setup guides, but market incentives currently favor frictionless cloud onboarding.
