It is part of Rule Machine

I just watched part of this, it is pretty good and will show you exactly how to do the if/else.
You may also be interested in this app which can do it for you among other things.
You have to use CustomAttribute as a trigger in a rule.
Here is what I have for my Ecolink Chime Siren; I assume this device has a similar custom attribute.
Pushover has been good for me.
I have 4 Z38s and a Titan w/ battery pack, so here's my alert rule as another build to consider...
These devices are placed to monitor the main circuits in my house. Since I sometimes intentionally shut down a circuit for something quick, I gave myself a 5-minute window in this rule. I built in a Refresh after the 5-minute wait just to help confirm what's afoot before sounding the (proverbial) alarm.
My hub is on a UPS, so I also use the Power Outage Manager app Jeff mentions above -- that gives me a backup notification if all power is out, and when power is restored.
Works perfect. Thank you!
No major changes, mostly just maintenance and code upkeep.
Version [1.0.6] - 2025-02-15
there is now a built in driver for this.. is that yours .. if not how does this one differ. thanks
Its not mine that I am aware of. I have never used the built in one so not sure what the differences are, someone would have to test it out and compare. If the built in one does not have all the settings available that might be the only difference, otherwise it is a pretty simple driver.
ya just switched it does not have the parameters but does report battery vs mains as far as i can tell.
is it possible to add the range and power level test like the aeotec extenders
i hacked changes to the driver (sorry lol) appologies to denny page where i got the code from...
seems to be working.. not sure if you want me to send you or post it or do a pull request or do nothing..
thanks
For something like that you could send me the full code in a PM if you want. Link to github or pastebin would work. Then I can do a diff and merge it, and I may adjust it slightly to fit my code style if needed.
@jtp10181 ... thanks for doing this 
We recently had a power outage for an extended period due to thunderstorms. My hub, internet routers, are all on UPS. The home network wasn't impacted and I was able to shut down critical devices gracefully. However, I'd been putting off purchasing a "Power outage" detector of sorts. I came across this post, saw what you've done here, installed the driver and initiated the purchase on the same day. When the ZAC38 arrived, it installed and then picked up the driver on its own! Unplugged and plugged it back - notifications show up as expected on our phones.
