Yes, you will be able to use your plugins with version 2.0
The plan is for plugin developers to get a beta copy of 2.0. We were asked to test our plugins and if anything breaks to let HST know about it and to not change our plugins. They want to make the changes in 2.0 so the plugins work with no changes to the plugins.
Great, thanks for the replies. I don't know what I would do without my favorite Homeseer plugins which includes:
Caddx Plugin by Nitrox
Ocelot Plugin by McSharry
WAF Caller ID by Kindred
MLHSPlugin by Krumpy
I really wouldn't use Homeseer at all if it were not for those plugins!
