Title: Switch an old valve amp on and off as required
Post by: purps on January 27, 2012, 11:46:51 PM
I was looking at some old valve amps with the aim of using them with LMCE. I was thinking use it with a z-wave plug adapter like this http://www.uk-automation.co.uk/products/Z-Wave-Appliance-plug-by-Everspring.html

My question, is what would be the best way to set up LMCE to turn it on and off? Obviously I want it to come on when it's needed (TV, audio, videos), but switch off after a period of time when not in use. Is this feasible?

Cheers,
Matt.

additional code would need to be added to the media plugin to handle "Power" pipes.

Another option would be a duct tape solution: Create a device template for the amp. Power On would execute a commandline messagesend to the Zwave device for power on, and power off in the device template would be the same for a commandline messagesend to the Zwave device for power off. Don't ask me about the ruby syntax in a GSD for commandline execution, but I am sure the wiki has something like that.

I've got a manual solution for my valve amp. I use a Tellstick controller, but the solution will work for any power controller.
Add a wall outlet device (#1897) and connect it to your power controller. Add any adresses/config needed and test that it works from the web admin.
Then add two scenarios - in my case it goes under Climate for unknown reasons - one for power on and one for power off. Regen orbiter and - viola, now there's two buttons on your orbiter to power on and off.

But posde's solution looks interesting, I'll investigate it.

Just looked at the wiki. This might be helpful, and a bit less "duct tapey":

Thanks chaps, some great ideas there.

Joakim, I was hoping I would at least be able to do it like that, so that's good to know.

I will look into the more automated solution (either/both the duct tape method and the proper method) in slower time (house move in a few weeks, still got two workshops to pack up!!)

Cheers,
Matt.
