Allowing a device to send values for its sensors in bulk

[longthanhtran]

Allowing a device to send values for its sensors in bulk, up to 500 values for each of its sensors instead of just 1.

• If the internet goes out in a home, the AC unit will reconnect when it can to the wifi and send all the data to our servers that it couldn’t send before. After that, it will continue sending data normally, once per minute.
• Should our servers go down, the devices may retry a few times. Repeat attempts will pack values together until our server goes back up.
