Also factory reset the one that won't add, sometimes that wakes them up

How old is your plm? If you're not sure, there's a sticker on the back with four digits, post those digits

Lake Michigan near Petoskey!

I get it... we spend a lot of our time camping around the Great Lakes, in fact we're out now 😉

Hot and cold temps are a factor... but my experience with those is the frequency of activation... the more they're used, the faster the batter dies. My experience with these and Insteon motion sensors is that when the batteries run low or dead they get flaky, it helps to factory reset them and right click on them in iox and pick restore device.

I would also pick a device that's in a scene with several other devices, right click and pick "restore device"

The new plm may have gotten 'confused' by the initial bad restore. I would try: Factory reset the PM: Unplug the plm from the wall, press and hold the set button while plugging it back in the wall, keep holding it until it beeps Unplug the ISY, wait about 10 seconds, plug back in, give it a couple minutes to fire up Try to restore the backup and then restore plm

A possibility is that the PLM was so far gone that when you backed up, you backed an empty and/or corrupted PLM data table.... and that's what was restored. Do you have a good backup from before the problems started? Restore that and then restore the PLM, retest

Is there an outlet that is between the buildings, or any electrical lines to something like a lamppost where an outlet could be added and a dualband device like a lamp module could be plugged in and put in a weatherproof box? Dual band lamp type modules will repeat the insteon traffic in both directions. If the power drop is close enough to both buildings it's plausible that it will work.

If you go to the programs tab, and then to the Summary sub-tab, take a look at Next Run Dates/Times for these programs and see if they make sense. When I first switched from my ISY to eisy, I had similar problems. I believe it was resolved by letting the eisy run for a couple of days and then it cleared up for good. Take a look here

I found your other post. The center button is used for linking. Take a look here https://support.insteon.com/support-knowledgebase/tag/2473SWH

Hi What are the devices / model numbers?

You'll need to configure Gmail to allow your home automation controller to send notifications. Enable App Passwords – you need to generate an App Password in your Google Account settings. This is a special password that allows third-party apps to send emails without requiring your main Gmail password

Most of the plugins have a trial period. You can try it, if it doesn't work the way you like, uninstall it

We're kinda getting to the fringes here problem solving wise... Did UDI have you replace the data cable from the eisy to the PLM when you upgraded? If a specific lead was broken, that possibly explains it.
