Hi, I just got a charger installed and its working great however I am struggling with implementing it with my Home Assistant setup as the power output only seems to update every 5 minutes which impacts my energy usage and solar usage quite considerably. Is there any way to change the 5 minutes to a 1 minute interval for the update interval? Otherwise is there a way to access the API directly over wifi or bluetooth without using the cloud implementation? Most other chargers I looked at were able to do this but I cannot find a way to implement this at the moment. Thanks
At present there is no way to change the reporting rate or use another comms channel. What is it that you’re looking to set up? If it’s about maximising self-consumption of solar then I’d recommend just turning on that option in the charger - export is monitored multiple times per second to see if the charge rate needs to be altered. But perhaps that isn’t what you’re looking for? If you let me know then I can see what we can do.
Hi Tom. Thanks for your response. I am implementing the charging into Home Assistant where it also monitors my power use for the house. The issue with using the solar diversion in the app is that it will suck all of my solar and not leave any to power the house which will then be powered from the grid. This way I can monitor my solar output, house power usage and charge the car with the excess that goes into the grid. I’ve got this set up but as there are so many variables involved it changes quite a lot within 5 minutes between power usage and solar. I have a 10kw system.
I would expect the charger to handle that scenario for you automatically. It should behave as a “tail-end” consumer so all the house consumption is factored in before looking at what is available for the car. So if your panels are making 7kW and the house is using 3kW then only 4kW will go into the car. Then if a cloud comes over and the panel output drops to 3kW, the car will stop charging as there will no longer be any excess.
If that isn’t your experience then it’s possible that the CT has been installed on the wrong wire - what we need to monitor is the main incoming (or outgoing!) supply to ensure that we really are the “tail-end”. I’d suggest calling our support line (1800 959 377) to talk it through with someone who can take live readings as you try out some scenarios to check that everything is correctly set up.
