Ethernet based home automation system

-

hey guys,

i working on building home automation system using ethernet based connection. controlling appliances via relays , needed advice regarding selecting relay controlling 2 ton air conditioner.

i have found relay seems have high current capability of 30 http://www.seeedstudio.com/depot/grove-spdt-relay30a-p-1473.html
will enough 2 ton ac . other alternative measures can suggested switching ac appreciated.

thanks

the relay can handle fine, worry connections wires.  things carry 30 amps, lot of power, have big connnections.  little heating there cause arcing, cause more heating until connection burns up.

take close @ ssr (solid state relay), these can controlled directly arduino , isolate control ssr pretty effectively.  last long time; i've never had failure.  have big connectors.  don't make noise.

just thinking though.

Multithumb configuration params not working? - Joomla! Forum - community, help and support

hi, i've installed multithumb 1.1 on joomla 1.011 site , works fine in basic set-up (and jce-editor). except when try tweaking mambot params, things stop working. specifically: if use "only in these categories" setting , fill in categoryname, e.g. "news", pop-ups/thumbnails stop working, categories, including "news". if use "not in these categories" these categories still use pop-ups. if select "use thumbnails" "no" not no thumbnails no pop-ups anymore. so way use multithumb selectively use optioni "apply content {multithumb}", bit cumbersome. there more people having these issues? hi bikey, i having issues bit different - yet same.  saying have way set configuration plug-in.  not know how find cong this.  if can maybe read posting - don't bore process.  jce editor - have not installed - still using default html editor - cant recall name.  why not see config file? anyway - find if use static page , pass com
