I’m so glad the continuous logging is working for you! I have another update in the works because I’ve found it still creates unnecessary number of log files with some SD cards… but it all seems to be variation in the wake-up process. Anyway, I digress.
The low voltage input (labeled Ω) is protected up to 600VAC. So you haven’t damaged anything, it should be totally fine. The protection circuitry does heat up though, and it can throw off your readings for a few minutes afterwards until it cools down.
