I ordered two DIY pro kits (with the TVOC sensors) earlier this month and went to start working on them yesterday. After flashing the firmware, neither one would create a hotspot for me to connect to. Looking at them and doing some googling, i found they include knock-off Wemos D1 minis (labeled "mimi"). It looks like they're aware there are Wi-Fi issues, but the chips are still being used [0][1]. I sent in an email yesterday but I'm not expecting a response until at least tomorrow.

Customer support will be in office tomorrow and we are sending a free replacement to all customers that have been impacted by a non working D1.

The "Mimi" version should not have the problem and we found it to be very stable and it is currently our default version.
