The Python request library periodically uploads temperature information to the yeelink platform and modifies RC. the local script enables the Python script to run in the background at startup, and reports the temperature information to the platform every 5 mi

connecting to WIFI, the IP address of Raspberry Pi is displayed on the tray icon. [SHH] With the IP address, you can use SSH. Use putty to connect to SHH: User name: pi Password: raspberry A dialog box will pop up during the first connection to talk nonsense. Just click OK. Disable standby] However, in this case, th

Raspberry Pi-rsync and Raspberry Pi rsyncYou can use rsync to synchronize folders between different computers. You may want to transfer a file from your desktop computer or laptop to your Raspberry Pi and keep the file updated. Or

after the first two steps our Raspberry Pi has worked normally, but before actually using it to develop some column configuration and software installation, so that the development will be handy, below we introduce the common software and services1. Configuration options:The first time a Raspberry Pi is used, a simple

Background: Raspberry Pi has been very popular in the past two years. It is very small and only in the size of a credit card. Many companies are also using this, And I have bought one to play. This is really a good choice for people like me who like DIY. There are three versions. I bought green boards. Recommended reading: Raspberry

route is very simple, that is, reading the index template (the template is html) and sending it to the client (browser), because the path is "/", that is, for example, the IP address of Raspberry Pi is 192.168.0.10. Use http: // 192.168.0.10: 8080 to access our "/" route (the default port of the bottle is 8080) Similarly, the second route path is "/cmd", that is, access http: // 192.168.0.10: 8080/cmd to a
