trying to use this node with after upgrading to current version. Seems to crash node red and I have to restart in --safe mode. Since this is the only node that works for what I'm trying to do I was wondering if anyone else has had the issue.
That isn't a node I've seen mentioned in the forum before and not one I'm familiar with.
Looking at its GitHub page, the node was published 4 years ago and hasn't been updated since. There is an open issue asking if it works... Issues · theminor/node-red-contrib-tcc-honeywell · GitHub
So I'm afraid to say you may not get very far with it.
