Uninterruptible power supply for the node



  • Hello!
    Recently, I thought about the autonomy of the system in the event of a power outage. In order that in the absence of current in the network of my apartment all the nodes of the system switched to batteries. Make a standalone server and gateway (Raspberry PI) will not be difficult. But I do not particularly understand how to do this with Mysensors nodes in order to preserve their miniature sizes. Do you have any ideas on this?

  • Depending on what sensors you are using you may be able to just power your nodes from battery.
    I have MySensors nodes that report temperature in different rooms of my house that will run 2 years on a set of 2 AA batteries. You would not need any type of UPS for the nodes in that case.

    See this link for info on how to get good battery life from a MySensors node:

    I use it as the UPS for a Raspberry Pi running Octoprint. The built-in 5v USB connector is enough to run the Raspberry. And you get surge protection too.

    Ooops. I just noticed that you meant for the nodes, not for the gateway. Sorry.

    A lot of sensor nodes can run for many years, maybe even decades, on just two or three AAA's. It's rarely an issue if they're well designed.
