Switch KH to Input registers #512

Closed canton7 closed 5 months ago

canton7 commented 6 months ago

See: #505

canton7 commented 6 months ago

I'm probably not going to merge this -- I'd rather do something intelligent using the manager version if we do get confirmation that input registers are gone for good on the KH.

williamjeccles commented 6 months ago

@canton7 agree, hold off until I hear back to from Fox, if they fix it in the next version this patch isn't needed. I will update you.

canton7 commented 6 months ago

Apparently Fox are working on a fix.

canton7 commented 6 months ago

@williamjeccles give that a try, see if it re-enables min/max soc, max charge/discharge current and work mode

williamjeccles commented 6 months ago

@canton7 appears to not work, all my values are unavailable and I see the following in the logs:

This error originated from a custom integration.

canton7 commented 6 months ago

Are you comfortable using modpoll? If so, can you try reading register 41000 on its own, and as part of a block of registers?

We've found that some holding registers on the H3 can only be read 1-by-1, so maybe that's what's happening here.

williamjeccles commented 6 months ago

@canton7 can you confirm the modpoll command?

I'm using:

canton7 commented 6 months ago

That suggests the ip address is wrong, or your modbus adapter is offline? Or maybe HA is connected to it, and is tying it up?

williamjeccles commented 6 months ago

@canton7 any better?

That looks more promising...

Can you try with -0 -1 -t 3 and -0 -1 -t 4? If either of those works (manages to read a value), add in -c 2, see if it still works.

Interesting that it's available to read as an input register. Can you try with -t 3 -c 2?

It lokos like we can read those registers 1-by-1 as holding registers, but the USR-W610 will really struggle to do that many individual polls.

canton7 commented 6 months ago

Actually, mind trying to read 41007 with -c 2, and both -t 3 and -t 4? The problem might be that register 41001 (which is TBD in their spec) is unreadable.

So, looks like they can be read as input or holding registers, but they have to be read 1-by-1.

It's probably the same as the H3 in that respect. Have a try with that latest update, see if that works.

canton7 commented 5 months ago

Released in the beta v1.10.0b3.

(It'll be a little while before I can get a proper release out, as we're in the middle of figuring out force charge/discharge).
