Yeah... That requires a standard way to communicate the energy price to the fridge. You won't get that with municipal regulation.
And without devices auto-adjusting their behavior, you won't get a lot of savings.
- rootusrootus 2y agoIt could just be telling it what your time-of-use rates and hours are. I think most places with variable rates at this point are on a schedule that does not often change, only a few places have completely dynamic pricing that would need real time information from the grid operator.
- Scoundreller 2y agoGenerally Time of Day electricity billing is just an average costing at fixed windows of time. 2-way (or really, just 1-way is actually necessary) comms not required. Not too common to have totally dynamic pricing. And even if you did, they have general trends.
- TeMPOraL 2y agoYour fridge doesn't need to know energy prices. Fridges are for cooling, not computing your bills, and giving them access to too much data only encourages the usual IoT vendor abuse patterns. It should be enough for it to get a proxy signal. "Cheap tariff" / "expensive tariff". Or maybe continuous 0-1 control signal. Optimizing energy use for household or building already requires an external decision-making center anyway.
- bronson 2y agoBut it does need a warning. If the two wire suddenly tells it "expensive tariff," that's too late to cool down a little.
