Smart Grid: when the connection to the broker came back (a Home Assistant restart, a WiFi blip), the Smart Grid state was re-announced as "Free Running" whatever the relays were doing. The real mode is now reported, and kept retained so Home Assistant shows it after its own restart too. A restart of the board itself still comes back in Free Running, as the relays do. Thanks @rogervdh.
Rotex protocol S: "Delta-Tr(deg)" is the weather-dependent leaving water target and is now named "LW setpoint (main)" like on the Altherma units, so the drawing and the card show it as the target next to the leaving water. Its Home Assistant entity gets a new id (sensor.espaltherma_lw_setpoint_main). Thanks @TungstenE2.
Detection report: the heat pump survey now also reads the software version of the hydro board (iu_sw_id), the one the hot water / leaving water target control depends on. It tells which boards are in use and which the control should learn next. It is part of the report sent when the "Help others" box is ticked (it is by default); See exactly what is sent shows it.
Home Assistant card: v1.0.10 (unchanged).
