#loadsharing — Public Fediverse posts

And that's called Load Sharing ;)

TLDR: I've been working on a way of using #HomeAssistant to replicate the #loadsharing functionality of our #OpenEVSE charging stations using #nodeRED. So far, so good ;)

There are quite a few rules:

1) If one of the stations ‘goes offline' - ie it drops off the network, we assume it's pulling its maximum current, and restrict the other one to 6 Amps.

2) Both stations default to 6A when charging has finished, regardless of if there's a second vehicle connected. 6A is the minimum because if we go to 0, it can cause the car or the station to not properly detect they're connected.

3) The system looks at the current being drawn and the limit set, if the current draw is more than 2A lower than the limit, it'll drop the current limit, and allow the OTHER station to get MORE current.

4) They're not allowed more than 40A between them :)

Should I put it on GitHub?
