I’ve decided to build a thermometer from scratch. I know, I can buy it, but it’s not fun. I found it as a perfect occasion to please my wife (she wants it) and to try new things. What new things? Mainly resin.io and resinOS.

We decided to hide some EC2 instances in private subnets (VPC). They’re accessible via bastion hosts or via API (API Gateway & Lambda).

Additional time for infrastructure. Can handle it, but it’s tough sometimes.
