A bit difficult terrain until #2, but then really nice until #9 or so when my fitness ran out..
Mistakes at the start into #2 (passed really close on the first try) and direction into #3 (should have found the dashed stream?). Otherwise quite easy running along roads and paths. Sunny and +15 C or so.
I made a new batch of the SFP Breakout Board.
With a 1 Gbit/s SFP transciever the bandwidth when transmitting from the TX port of one board to the RX port of another board seems to be almost 1.8 GHz.
I got this husdata datalogger for my heat-pump.
It plugs in to a 3.5mm audio-connector inside the electronics box of the pump. On an IVT geo 312C pump it's fairly easy to install by removing the big front cover, then a smaller black cover, and then opening the electronics-box. I routed the wire into the pump via a tube-hole at the top, and then through the cable-hole of the electronics box (lower right). It plugs into a 3-wire 'BBT' interface.
The datalogger reads info from the pump and broadcasts it over wifi either to the husdata-website or over MQTT to any compatible device.
The start was on a road wher this crazy youtuber did an everesting...
Drifted onto the wrong hill at #8, otherwise mostly ok. Not the nicest terrain to run in... +15C and sunshine.
