They are currently shipped with an TYWE3S which is an ESP8266 (as of June, 2021). You can see the pin outs for the TYWE3S at the Tasmota site.
Use a thin utility knife to open, I would recommend starting at the USB port area. There are two tabs on either side, and a few spread throughout. Once you have the device open and have connections setup you are ready to flash.

Hello,
I do not support Motion B6 – Don't Feed the Wildlife, submitted by Pete Fry.
The proposed ban is overly broad, and unnecessary. There is already a Park Board bylaw on banning feeding wildlife in our parks, which is the advertised target of this motion.
The City and Park Board should enforce existing bylaws, instead of adding new ones. And, when necessary, work with the province on enforcing laws against feeding dangerous animals.
Pete Fry stated that the proposed bylaw is also meant to target people who attract vermin to their properties. Does the City not have bylaws in place already that cover this? I believe they do.
Many residents in Vancouver feed the various birds in their area using methods banned with this proposed bylaw (i.e. putting out nuts while under observation in a container during the day: to prevent vermin), and use it as a way to improve their mental wellbeing, especially during COVID-19. This will unfairly target seniors and people with restricted social circles.
Please consider voting against this motion.
Thank you.

My partner and I purchased a new home, and it came prewired with CAT5E, and outside rough-ins for security cameras.
With those requirements in mind, I settled on the following hardware from Ubiquiti for an end-to-end solution:
I decided it was time to get "serious" and have a proper pro-sumer setup at home for Internet access, and while we were at it: Security cameras! I didn't want to go with Hikvision or any of the other Chinese manufacturers of IP cameras.
For security cameras (UniFI Protect), I went with the following:
These products, in my opinion, are not prosumer. They have a number of issues, especially for the price point (I would expect better.) In a lot of cases, pfsense would buy you better bang for your buck.
I have replaced the UDM with an opnSense install, but I don't know what to do with my existing cameras as it was not a low-cost or low-effort investment.
Ubiquiti may be "okay" if you're not doing anything complicated, but at that point you might as well buy a cheaper solution that "just works" and doesn't arbitrarily have features removed or just plain not working.
