**** BEGIN LOGGING AT Sun Dec 31 03:00:02 2017 Dec 31 04:14:53 -->: would be cool to have a kind of rotex cape that could extend the box for controlling home micro grids with solar and a heat pump or so Dec 31 04:15:37 Get weather forecast and then derive a control strategy to save some bucks Dec 31 04:16:39 Or hook up your sma sunnyboy to it Dec 31 04:16:41 define rotex Dec 31 04:17:14 As far as I understand it's a beagle based controller for residential heating systems Dec 31 04:17:46 http://www.rotex-heating.com/heating-control-via-app.html Dec 31 04:18:09 Oh cool they have that Dec 31 04:19:37 Basically you want to maximize self consumption as an owner of a solar system in Germany given the feed in tariff regulations Dec 31 04:21:27 Seems Rotex is a company. And they have various products. No standard jumps out as to what they are doing. STandard interfaces exist in most systems. Likely they have there brand of controllers and custom interface. Dec 31 04:23:07 Yeah they are building beaglebone based controllers Dec 31 04:27:52 Again standard interfaces exist for all that stuff. However it does require some work. For example you can make a thermostat to run your furnace and AC because all the connections are mostly the same and the controls are on off. Solar power et al is a different matter that requires an inverter that syncs with the grid power. Dec 31 04:28:16 It's not likely they are doing anything all that special. Dec 31 04:28:34 However they have something that works. Dec 31 04:30:06 Yeah true. Data exchange between different inverters / trackers and loads is still a major nightmare. Even between model generations of the same manufacturer. Dec 31 04:31:00 But if you can cover the complete system e.g. on the DC side you can work with that Dec 31 04:32:33 For larger systems the DOE has an interesting working group called orange button initiative. They are working on a XBRL derived standard for data exchange Dec 31 04:36:27 And for micro grids - no generic control for in the horizon. Still very technology specific Dec 31 04:36:41 * Dec 31 04:36:46 storage Dec 31 04:39:51 most of the micro grid stuff self controls (because it's designed to automatically sync to the grid) if you use micro inverters one per panel you actually have 0 configuration to do. They supply your local power as much as they can and if you demand more it comes from the outside grid. Otherwise it gets fed into the outside grid. Dec 31 04:40:33 If you want to store power that's a bit different and more complex. Dec 31 04:44:02 Well that and then adding small wind or run off river hydro Dec 31 04:44:22 Plus makjgnsurenthe fridge in the local pharmacy always has juice Dec 31 17:41:50 you know, the worst part of OS dev is porting in a userland to make use of your KERNEL Dec 31 21:17:53 3~so how is everyone Dec 31 21:17:56 very quiet in here Jan 01 01:45:04 guess everyone is out drinking **** ENDING LOGGING AT Mon Jan 01 03:00:00 2018
