When doing my own Z-Wave installation I have decided to make it without rush with simple steps. As such I have started with measuring temperature. When I moved in I have prepared for this 6-wired cable going along the garage wall and outside to the garden. My RazBerry controller is waiting at home and I gather equipment. I plan to limit soldering and use more connectors – some may be too big but I do not make precise probes (yet).
In this article I will come back to installation of home controller based on Raspberry PI and RazBerry daughter board. I will try to start from very beginning. In later posts I will be building environment around this control station – if I change my mind I will clearly describe it 🙂
For controller I want to use Raspberry Pi 3, RazBerry daughter board and system will be installed on 32GB card. I do not claim it is the only solution – but easy to start.
A few years ago when moved to new house I had a plan to introduce some automated system to control heating at first. Key reason was that I was very unhappy with heating system which was based on hot steam provided by power company. Problem was that with several houses on single connection there was huge loss and problem with getting satisfying temperature at given moment. As I had no clear idea at the beginning I though about building some wireless system which would allow me to control different components of the system.
That time I had Raspberry Pi and found out about Z-Wave.
This is my third try with rennet cheese – the second one was a complete disaster.
During my first try I used 4 liters of cow milk bought from the farmer at local market and pasteurized it in around 70-72°C. However as the process of heating it and on my oven and then cooling was taking some time I decided to use next time pasteurized milk from shop 3.2% fat. I knew UHT is useless as due to high temperature lactic bateria (LAB) dies – and cheese will fail. During my second attempt shop bought milk failed to make thicker consistency. I tried to rescue this but eventually after two days whole stuff was thrown out 🙁
This time I have prepared the following ingredients:
