Pyssel

Updated 2024-12-13 ! When starting up a new project with Raspberry Pi I like to start up fresh and with a minimal OS.  Therefore i always use Raspberry Pi OS(ROS) Lite and then adding what I need .  Doing it right You don't have to use an external display, keybord and mouse, just a " ssh "  client. Flash to a SSD ? Check this post .

  Updated 2024-12-01 ! In my underfloor heating project, using Node-RED, I have to have one sensing thermometer per room/zone, seems to be 8 in total, so therefore it would be nice with a wireless battery sourced device with good resolution and frequent updates. During the test phase I used a Z-way device but the resolution was pretty bad. Another device mentioned is  the  Ruuvi tag  but since it's a bluetooth device the transmitting range could be better. After some googling I went for 433 MHz devices.
