How obniz is different from other platforms
Your programs run on your own system, so even we don't have any means to see it. Also you are free from microprocessor's security issues, because your code never runs on the obniz itself.
In the very beginning, an obniz accepts anonymous access. However, after the ownership procedure, you can generate access token for each obniz. No one can connect to your obniz without that token.
obniz.js is opensourced and it is updated frequently. Using the latest version will ensure the best security. Also, obniz firmware can be updated via the obniz cloud
obniz will stop driving the io when it detects overcurrent or overheating of the driver in 5v push-pull mode. It will automatically recover from shut-down.
obniz alerts the user when power supply voltage becomes low.
