FoxESS Community - Owners & Installers Forum

Hi,

Had a new system installed this week with 2xH1 inverters, each with a pair of batteries and a Wifi Datalogger.

The Fox Cloud is OK, but pretty basic and ultimately i'd like to integrate it into Home Assistant for more accurate visualisation etc but the FoxESS Cloud integration, while pretty cool, is always slow to update.

Given i have the Wifi dataloggers, and they're on my network, I was wondering if they support anything more interesting? ModBus would obviously be the simplest but i can't find anything on my network listening on the standard tcp/502 port. Is this something that can be enabled somehow?

Failing that, is there any kind of interface to the datalogger that I can potentially query for data? I'm a software engineer so happy to write somethng to scrape the data etc

Basically I'm trying to work out if what I have is enough, or if I need to consider anything additional? The inverters are installed outside so i'd rather not be drilling any more holes through walls if I can help it

There is no direct connection available to the dataloggers, they send packets of data to the cloud every 5 minutes and that can be accessed in the cloud.

If you setup a home assistant there is a cloud interface that gathers all of the totals and 5 minute samples as sensors which works ok - but is obviously dependent on the Fox cloud which can be temperamental - this is a link to the cloud integration https://github.com/macxq/foxess-ha

Or there is a modbus integration that provides real time access to the inverters and allows you to control them without needing to use the cloud - here is a link to the modbus integration - i've linked it to the wiki which explains wiring and suggests some adapters that work well (but ignore the USR W610 that can be a bit slow). https://github.com/nathanmarlor/foxess_ ... ring-Guide
