Venue 45 - Lascar loggers

Venue 45 was able to deploy a bunch of Lascars at once - commercial USB-stick loggers that also record temperature, and relative humidity if you pay enough. We can’t always support this, but it can be useful for understanding balance and circulation problems and thinking about which rooms are really struggling with heat loss.

We haven’t looked at whether the Lascars handle the clock change so it’s possible that they go an hour out at that point.

You can get a line to disappear by clicking on it in the legend.
