_(That +3C in the name is just to remind me that it's reporting about 3C above the actual temperature)._

Sorry taken a while to get back to this, I was uploading every 4 results and powering over USB.

Has there been any improvement here? If not I'm wondering about trying to alter the code to do the data upload on a different cycle to reading the data.

Just spotted this is probably the same issue as reported in #134

I just reported issue #137 against the pico enviro indoor where I am seeing a similar increase in reported temperature of 3 to 4 C when running on USB power.

In earlier versions I wasn't able to get it running whilst powered by USB. So it would have been on battery power then.
