Tech updates: heating schedule thoughts...
Considering the optimal method to choose the distribution for randomising the scope for consulting on considering a grass-roots movement to form a citizens' assembly to set terms for a Royal Commission to guide the forming of a ministerial task force to consider the scoping and creation of a focus group to sketch terms of reference for a study group to outline the agenda for a pre-meeting to form a steering group to get ready to think about upgrading the RPi server, easy does it...

2025-07-10: Heating and SSES

Mid-summer and temperatures in the 30s (°C) is obviously an optimal time to tweak the heat-pump weather compensation adjustment schedule.

(Do not look at me in that tone of voice!)

Thus I am now looking at when there was actually a call for heat to the boiler ("b":1) seen in the OpenTRV data January to March this year. (I am ignoring the effect of the clocks going forward at the end of March, as we turned the heating and the boiler controller off . So UTC times are good.

(Maybe I should have looked at the data before devising the new SSES-friendly schedule ... stop scowling at me!)

Raising the flow temperature in the hour from rather than as previously in the hour from may make a noticeable difference.
