Why do PV1 Power Total / Grid Consumption Total / Feed-in Total / etc show "Unknown"?

(And yet other sensors are showing correct data).

These are Riemann sum integral sensors provided by Home Assistant: they sum up the total energy seen on the corresponding "PV1 Power" sensor (etc) over time.

For some reason, Home Assistant needs to see a number of power values before it starts displaying a sum. Just leave it for a few hours and it should sort itself out. If your "PV1 Power" etc is showing 0 (e.g. because the sun is down), you may need to leave it until you get some non-zero values.

How do I configure the update frequency of some sensors? I'm worried about network traffic / bloating Home Assistant's database

This integration reads multiple registers at a time (rather than one at a time, as StealthChesnut's integration does). With a good adapter (i.e. not the W610), we're able to read all registers in 2 read operations. It's therefore significantly cheaper to read a register than to avoid reading it. We also only tell HA that we've updated a sensor if its value has actually changed, so reading a sensor which isn't changing is practically free.

If you're still seeing too many values added to Home Assistant's database from sensors which change a lot (e.g. PV1 Power), there's an option under "CONFIGURE" to round and filter the worst-offending sensors, which should significantly improve the situation.

How do I change my inverter settings ?

(For example, change the IP address of the inverter, change from a direct LAN connection to an RS485 adapter, or add another inverter).

In Home Assistant, go to Settings -> Devices and Services. Some settings can be changed by clicking "CONFIGURE". Otherwise, remove and re-add the integration by clicking the 3 dots in the lower right, then Delete, and re-add using "ADD INTEGRATION" in the bottom right. As long as you keep the entity ID prefix(es) for your inverter(s) the same, your sensors and their history (and any customisations you've made) won't be lost.
