I would like to build a battery powered siren for alarm activations. There are commercial products that claim a battery life of 3 years.
I have read that for a mysensors node to act as an actuator, it cannot sleep?
I've searched the forum but there is not a lot of info in the past couple of years.
Just wondered if anyone has any tips for what I am trying to achieve.
So far I have ordered this: siren
@grumpazoid yes that's correct.
For your use case a mains powered node with battery backup is probably the best solution.

@mfalkvidd Sounds reasonable. I am thinking a small UPS would be a good idea so I could keep my raspberry pi's, router, switch etc going as well.
Time to look at that relay node then!
