Libbi Temperature #526

In the Libbi integration, there is a state 172: "BMS Charge Temperature Low" Has anyone ever seen this status? If this does indicate a slow charge situation that would be really helpful. Thanks for any help |

I have seen that status. IIRC the battery temperature was something like 2 or 3C. Charging was severely limited; it was 940W on the 5kW inverter. |

I have an HA automation that calculates my target Libbi SOC based on the Solcast forecast and then calculates the required charge start time so that the target SOC is reached at 5am when my cheap rate finishes. I hope to integrate this to the Libbi when @trizmark completes the integration being worked on.
The problem is that the charge time varies significantly with temperature (especially below 10 degrees C) so it would be very helpful to know the Libbi temperature. Temperature isn't on the status API https://s18.myenergi.net/cgi-jstatus-Lxxxxx but the historic API https://s18.myenergi.net/cgi-jday-Lxxxxx-yyyy-mm-dd has
ivt - Inverter temp
batt - Battery temp
batrt - Battery radiator temp
ambt - Ambient temp
contt - Controller temp
If temperature was available then this could be used to optimise the charge time. It would be great if some or all the temperatures could be available on the integration.
