Re: Why does my charge rate oscillate so much when ForceCharging triggered by HA ?

Can you confirm exactly how you're invoking a force charge with HA? I have a H1-gen2 WL on my test bench and it works fine with HA force charging.

Re: EVO Firmware

I don't see any post-factory firmware releases for the EVO product yet.

What versions are you running currently and i'll see if I can narrow down more information.

Re: KH inverter USB to Modbus connection query

If it doesn't have an integrated aerial like in this video, you will need to provide an external rs485 to modbus adapater.

Re: Foxess H3 overload problems

Running your whole house off the EPS is not recommended. You should install an ATS/Gateway so you're on the EPS port only when the grid is down.

Remember, your backup loads are 1/3 of the inverter's rating which is why you're seeing the overload.

Re: Fox ESS Evo 10 parasitic drain?

Sounds like the inverter is still running even with limited load so you’re seeing the worst case system losses or battery warming maybe?

Once the system is commissioned check back in should you need any help.

Re: Number of calls per day:0 Remaining calls for today:0

Is it resetting at mid night each day? Are you using any VPP providers as it all counts towards your api limit. I believe fox can increase the limit if you're using a VPP.

Re: Real time update

If you have a H1-Gen2 WL or KH-WL you can ask Fox Support to install the beta software which reduces the poll rate to around 5-10 seconds from 300 seconds (5minutes). Note, currently only supported on the WL version with the integrated data logger but expected to be rolled out to all smart WiLAN and ...

Re: Does the fact the Inverter display has the wrong time effect the Mode Scheduler?

Your installer can correct the date/time and remotely install the latest firmware for you.

If you want to update the date and time on your inverter, it's under settings > 0000 > date/time

I would also make sure the timezone is correct in your site's settings.

Re: Does the fact the Inverter display has the wrong time effect the Mode Scheduler?

Hi,

Yes, the inverter date/time being correct is critical you can manually correct.
If it continues to drift, make sure all your firmware is up to date as older versions had an issue with the inverters time not correctly syncing with the cloud.

Re: Wallbox Homeassistant integration

Just to confirm because "wallbox" is a brand of charger but I assume you mean the EV charger fox sells.
If so, currently there is no integration for this but I hear that fox will soon be exposing modbus registers with the AI link and then you can HA to the fox AI LINk box and pull data from it ...

Re: Anyone else having issues using the Octopus Agile mode scheduler?

I know major effort is going into the new mode scheduler with better agile support. It might be worth disabling until the next big fox update comes out.
