Uninterruptible power supply for the node

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.
