Yeah that's the error I expected. There is still something wrong with the removal on occasion and everyone just points fingers at the other party and says it works fine here. Nodes that get stuck in "Pending" like that seem to be the worse. 95% of the time it seems to work fine these days.
If I had time to try and reproduce one like that I really want to get some zniffer traffic and see why TF the zwave chip thinks it is getting a response from a dead node. Supposedly the HE system just sends commands to the zwave processor and that is what is refusing to remove the device and kicking back the error message. The software on the zwave chip is provided by Silicon Labs. So it is a hard thing for the HE team to overcome.
Hmm... I have an idea. When you click refresh a couple of time do you eventually get a "Replace" option along with the remove? Do you have ANY other zwave devices you could pair there temporarily? If you could get a device paired into that node, you could then do a proper exclusion which will remove it!
Here are my instructions on doing a replace: [Guide] Updating Firmware and ZWave Replace
