Why smart homes fail.
Consumer platforms optimize for convenience. Estates need resilience, separation, and accountability. Here is the gap — and how HouseCommand answers it.

Accountable by construction.
Every action — and every refusal — is written to a tamper-evident, hash-chained record. Nothing the platform does is unattributable. The chain below is real — SHA-256, computed in your browser. Try to get away with an edit.
Every command logged
Executed, confirmed, refused, recommended, rolled back — all recorded.
Tamper-evident chain
Each record hashes the last; any edit, insert, or deletion is detectable.
Verified actuation
Safety-critical commands confirm device state by read-back before they count as done.
Manual override preserved
Physical switches, valves, keys, and breakers always work — independent of the platform.
each record hashes the one before it. edit any record — silently — and verification exposes it. try it.
