I have six Peanuts that I removed from the network and my problems stopped. I originally bought them when I had a lot of the older Sylvania (Osram version) lights and they didn't seem to make a bit of difference in the frequency of devices dropping off the network. I started adding Samsung (as much as I hate Samsung) and Sylvania plugs and saw improvement in responsiveness and reliability with each plug I added. Just from the getChildAndRouteinfo table I see the new Samsung plugs repeat for up to 8 devices (at least what is listed on the table at the same time) and the Sylvania plugs repeat for up to 5. I haven't tried to do this since updating the firmware on the Peanuts, but I could get them to drop off the network just by switching them on and off rapidly from the dashboard. I would also have to rejoin one or two of them on a weekly basis; not the kind of reliability you want from a repeater. I'm pretty sure they are also the reason my Lightify 4-button controllers would not stay connected in areas of the house that had peanuts for repeaters. I now have all of the end devices on their own HE with all of my Samsung and Sylvania plugs (plus a few GE in wall dimmers) and have not had a single issue in over a month. I primarily did this to see if the Lightify 4-button controllers would work properly on another hub; one free from lights and peanut plugs. I have 9 of them that I bought when they were $8 each so it was worth the investment in another hub and they have worked flawlessly ever since.
I rejoined the Peanuts to my "lights" hub after updating their firmware, and am still undecided as to their usefulness. I have not seen a perceptible difference since adding them back, but Hub Watchdog (virtual switch) has been consistently slower ever since with no other changes except for the latest update. They may end up back in the drawer until next Christmas.
BTW the Sylvania plugs are on sale on Amazon 4 for $51
