2022-01-30: GSC Crawled - currently not indexed
Am I the only one to use the "Index > Sitemaps > sitemap.xml > Excluded > Crawled - currently not indexed" list as a clue for pages that could do with a bit of TLC and tweaking?
2022-01-18: GSC Desktop Page Experience
A Desktop Page Experience report just became available in Google Search Console and in the page experience summary I see the headline:
96% URLs with a good page experience on mobile
100% good URLs on desktop

2022-01-10: RE Utils V1.1.12
Working up to integrating the heat battery, I need to make the current grid intensity easily available, in the file system or over HTTP. The latter if I run a second RPi just to talk to the heat battery, possibly at lower power than a long RS422!
reutils release publishes live raw plain-text gCO2e/kWh value eg suitable to poll over HTTP, eg to decide when to fill a thermal store from the grid for hybrid DHW provision.
2022-01-09: Power System Tweaks
I need to reduce mid-winter load a bit (go back to just one RPi for example) or add a bit more generation (~250Wp of upward-facing / near-horizontal panel?). In the interim I have tightened up the power management code to be a little more protective, sooner, after an extended period of weather too dull to make the battery FULL.

2022-01-06: Sitemap Timestamp Tweaks
I was basing the timestamps in
sitemap.atom on the timestamp of the
.*.html source files. (Usually: if there was an insert for the file then its timestamp could win.) This was to avoid bothering search engines (SEs) with non-content changes, eg when one of the build scripts was updated, or there were some site-wide style changes.
But this was starting to get complicated.
These have now been changed to use the build time of the
.html HTML files. Note that the pre-compressed
.htmlbr files still may have later timestamps than the sitemap entries.
Also: AMP has finally gone from the GSC 'Enhancements' list in 'Overview'!
