Fourth beta for 2026.7.3. Everything from b2 (the measured-values-only redesign), plus:
- Fixed: a sensor blipping a few negative milliwatts could render as "-0.00 kW" on a chip; values rounding to zero now display as a true zero (#290).
- Added: a buildings download diagnostic in the editor's buildings section, under the force-download button: the outcome of the last attempt, mirror by mirror (building count, HTTP error or timeout). If your buildings are missing, press the button and the report names the culprit (#291).
Install: HACS > Helios > menu > Redownload, enable "Show beta versions", pick 2026.7.3-b3, then hard-refresh your browser.
