HOMELAB · THE BILL
The Ledger
One-stop and ctrl-F-able: every line item on the house hardware bill, six phases, one table each — chips for status, links to the vendor and to the page that argues for it. Prices are street; check before buying.

- ◆ decided The smoke/CO interconnect set is the first dollar this bill spends — before anything else on it.
- ◆ decided About $2.7k of the gadget tier is already decided: sensors, UPS, alarms, the printer, the radio.
- ◆ decided The mini-split stack — unit, install kit, install materials — runs ≈$1.3k all-in.
- ○ open Attic ($3–5k) and windows ($4.5–15k) are the two big ranges still waiting on a contractor count.
- ◇ someday The someday tier — generator, NG standby, cameras — stays parked: priced, not bought.
- ◆ decided Buy in phase order. The Overview holds the plan-of-record shape of all six parts.
On this page
Every row below carries its own status, its vendor link where one exists, and a pointer to the page that makes the case for it. The subtotal under each table and the grand totals at the bottom compute themselves from the rows — nothing here goes stale by hand-editing.
