Generic adapter to use excessive PV power by an EV Wallbox #629

Open gidhap opened 3 years ago

gidhap commented 3 years ago

What kind of device or service you would like to see an adapter for? Many ioBroker users own a photovoltaic (PV) system AND an electrical car (EV). One of the main challenges is to use the excessive power to charge the own EV, rather than sending the energy back to the grid. No matter if free or sold, sending to the grid is a loss compared to self consumption. So far many ioB Adapters for individual Wallboxes are available, but no solution for maximising self consumption. Everybody tries to invent "something" . So what I thought about: Why not creating an adapter which basically "only" provides a smart logic (if-then-else...) to manage the wallbox, based on several parameters and input/output values and command. The generic input/outputs could be linked to datapoints which are already existing in ioBroker (e.g. solarpower, feedback to grid, load, etc) and commands required to control the wallbox (e.g. start, stop, paused, max. power etc), which are available in many cases as well (APIs or even an existing adapter). Unfortunately I am not a programmer, but maybe somebody volunteers and other guys would be willing to test and donate ;) as well.

Is an official API including documentation is available? Several APIs available by various wallbox vendors

Are other libraries for an integration available?

Is this device already integrated in other Smart Home systems? Several adapters to connect various wallboxes are available

I like the idea, but would extend it also for other bigger enegery-consumers (dryer for instance, or a pump ... whatever needs "lot of energy".

SO The first this wpuld be to find rules and definitions for that and try to make it as generically working as possible - so someone from the users could write a small "concept" that described incoming data, configuration data, outgouing actions and such

About the original idea

Currently the https://github.com/iobroker-community-adapters/ioBroker.kecontact adapter supports this feature but only exactly for Keba wallboxes.

There is also the product https://openwb.de/main/ which aims to do exactly that - but is currently in no way connected to ioBroker.

About @Apollon77's suggestion

This would be a great idea, perhaps also a bigger "community" project.

I would also be happy about an adapter with which the excess energy of the PV system can be used sensibly. In the adapter you should be able to set the switch-on and switch-off values ​​and the data point to be switched. so you could switch pumps, switchable sockets, etc. An adapter where you specify everything in one instance.
