Siri can't find Home

Question

I tried setting a reminder in Siri on my new iPhone 5, like "Remind me to put my pants on when I leave Home".  This used to work on my 4S, but now Siri responds with "Sorry, I don't see 'Home' in your contacts." or "I don't know who 'Home' is."  However, I do have a contact named 'Home' and it has always worked before.  Using "Here" works, but it shows my neighbor's address, and is not useful if I'm not at home.
Apparently, it works for Mitt Romney.  “Do you mean summer home, winter home, vacation home, Swiss village, island retreat, Welsh castle or ski lodge?”

Answer 1

I had the problem that whenever I asked Siri to remind me to do something when I get home or to work, it would  respond with "Sorry, I don't see 'Home' in your contacts." or "I don't know who 'Home' is."
I sorted this out by reviewing my contacts. I had a big mess between contacts that were in my iPhone and in the iCloud.
So, I copied all the contacts from iCloud to my outlook (yes, with the new iTunes there is a plug in for Outlook).
Next, I erased all the contacts in iCloud.
Next, I went to my phone and erased all the orphan (unlinked) contacts in my iPhone. (There were 2 or 3 stragglers there)
Last, I carefully chose the contacts I wanted, making sure I didn't have duplicates (including for self) and copied them from my local contacts in outlook to the contacts in iCloud within Outlook.
My phone then synchronized immediately and when I asked Siri to remind me of something when I get to work she did it correctly. Also, I had to reset my relationships like, I had to tell Siri, my wife is so and so because when I deleted all the contacts to start fresh she got that relationship erased.
Now that my contacts are tidy, all is well. I hope this helps someone with the same issue.
Cheers.
