Why not just buy an ERV? It's available, comparable in costs, and in 5-10 years, there will still be parts, unlike this project where the author hasn't actually shared the most crucial component, the exchanger.
Canada checking in. Data caps have only recently increased. Note, I did not say things got cheaper. My understanding is the Canadian government asked for a lower $ per GB. This means by throwing data at customers that isn't needed, they're actually charging "less".
I think Starlink is a huge game changer for rural Canadian areas served only by copper, and to be honest, I'm not sure if Bell cares when the large cities are where most of the population is and that's where they can make their money.
Indeed. Rural areas have always been neglected due to The economic realities. It's just very expensive to build and maintain infrastructure out here to less dense populations, and realistically The big earners who could afford to pay high rates are all in the city. There are sometimes requirements forcing providers to deliver some service, but they will always do the bare minimum because there is just much more money to be made in the denser areas. Starlink is the first time where the script is being flipped somewhat. Starlink works better with less density. It is also delivering reliable and excellent service. I have been using starlink since it was very first available, and it has really been life-changing.
Left out is a bit of the saga of ratgdo and that it's not actually open source hardware. There is a separate effort in that space - https://github.com/Kaldek/rat-ratgdo
I have no issues with closed hardware and making money. However, the ratgdo maintainer will actively delete any references to other alternatives which I think is poor form and leaves a bad taste. Especially since his product relies so heavily on other open-source such as esphome, as well as the Security+2.0 protocol work that is out there (eg. https://github.com/argilo/secplus )
This guy has a few videos on his channel dedicated to the batteries.
