Looking for some collective brainstorming on the topic of using Homey as an Energy Management System. With the latest updates, Homey brought the Energy tab to provide insights into energy usage. And of course you can utilize flows to automate things, but I’m not entirely sure whether this is going t…

I think it depends on the algoritme you want to use, and how sophisticated you want it to be. The more sophisticated, the more probability will be involved which will lead to less understanding of what is happening. To give you an example: when I want to use the washing machine, I always switch it …

Agreed. Great example of the washing machine btw, I do have a smart washing machine which already takes into account dynamic pricing for it’s optimal start time. But once again; this system is on it’s own and does not take other components into account. For the washing machine specific I (and my wif…

[image] jsiegmund: But when these components don’t talk to each other this is hard to achieve. When this components have each individual time control, you can make an overall time schedule without an HEMS. Like setting the boiler temperature higher from 13:00 till 16:00.

Yes, I have already done so, but such a schedule does not align with the real world. Availability of things like solar power and energy tariffs are different over the course of days and months. The amount of energy needed for heating differs and I do not use my car every single day. A fixed schedule…

Interesting brainstorming here! I am in the middle of a similar project for my home. For now it is split around devices: Heat pump I use the power level of my east-directed solar panels to lower the water temp, to surpress the overshoot when the sun is shining. My south- and west-directed panels …

Nice! So have you done everything using just flow? From what I gather from your post I suspect your battery itself determines the best time to load? I already found a few drawbacks of the system I have in that it does allow me to schedule based on dynamic tariffs, but it will not calculate what the…

It would be nice if Homey would work with something like the S2 standard: https://s2standard.org/ These connections should eventually be standardized.

I am now investigating the possibilities of Solcast and how well that can be used to predict the solar production in my situation. I am using airconditioners to heat my house (when my solar power exceeds a certain value) and next month I will receive a battery. At this moment I am further making cal…

I have created a flow to control the export of the solar panels at a negative rate. Unfortunately I still have to manually set the value into the inverter because the Solis app does not yet have the function to set the power limit. (Make a suggestion :wink: ) After some testing and tweaking it works…

I’ve got a similar setup: I use several Eastron SDM230 kw/h meters and homewizard plugs to measure my connection to the grid (as I don’t have a smart meter), the power consumption of ‘heavy’ users (like a boiler, dishwasher, dryer, etc) and the productivity of my solar panels. I’ve got 2 strings o…

For the local app I believe you can find the people behind it on the Tweakersnet forum: https://gathering.tweakers.net/forum/list_messages/2306860
