 ## Known issues
 * ESP8266 won't restart after saving system configuration.
  Sometimes ESP8266 can't restart after a software watchdog timer reset, which is the only way to reset the system by software. It happened on my NodeMcu and D1 mini boards that didn't connect to anything but USB. I have no solution for it.
-* ESP8266 won't start after selecting WiFi network.
- The web server used is ESPAsyncWebServer which uses ESPAsyncTCP. I found that if ESP8266 ever enters SoftAP mode before connecting to the network, the Web server will fail on tcp_bind() and the web service will be unavailable. Not tracing the source code of the LWIP, I just worked around by reseting the system. However, ESP8266 sometimes doesn't reset.
 * The page can't be loaded correctly.
  It rarely happens after HTTP caching is used, but it does happen especially when Javascript Console is opened. During developing and testing, I found corrupted html/javascript pages. Without the abliity and time to debug or develop the web server and or TCP/IP stack, I decide to live with it.
 * Incorrect temperature chart.
  The log format before v2.0 is vulnerable. There seems to be some unconsidered conditions that break the log. 
+* The gravity caluated by the controller is slightly different from that shown on chart. It is because the formula are derived speratedly. Due to different float precision, the formula is different. The difference should be small, though.

 Note: The GPIOs of ESP8266 are not all **General Purpose**. Some of them has special functions, and might not be usable. For example, some PINs on my NodeMcu board don't work normally.
 **!!Important !!** It is hightly recommended to pull up GPIO0 and GPIO2 while pull down GPIO15 so that the system will start up normally instead of staying in bootrom mode in case the system crashes. Updating the system configuration and firmware also results in restart of system, and sometimes this issue happens if the circuit isn't implementated. Check this url for detail information:
