KH inverters no longer support input registers?

[williamjeccles]

Add support for the FoxESS KH 10.5 series, which currently appears to be unsupported.

[canton7]

Ah, they've changed something. We're looking for "KH-" at the start.

[canton7]

Opened #506.

[williamjeccles]

thanks @canton7 that makes sense, if you ping me the PR I'll test it for you if you like.

[canton7]

Cheers, can you give #507 a try?

[canton7]

Let me know if you need a beta to test.

[williamjeccles]

thanks, working on it now @canton7

[canton7]

Fixed in v1.9.0.

[williamjeccles]

@canton7 any easy way to prove this? Happy to manually run a patched version to help test and I can report back to Fox to aid a fix

[canton7]

@williamjeccles If you're comfortable using modpoll, that's a quick and easy option. Try reading holding register 31000 and input register 11000.

Alternatively, I've switched the integration to use holding registers for the KH in this PR: #512

@canton7 bingo

now working just with some of the BMS and controls for SOC / workmode broken.

Let me know what I should report to Fox unless you have connections in Fox R&D?

[canton7]

Cool!

I don't have any links to Fox R&D, so if you could get some information on whether this is intentional that would be fantastic. If it is, we can switch the integration to use holding registers from a particular manager version onwards.

The information we have is that the KH used to expose input registers as well as holding registers, but somewhere between manager version 1.16 and 1.18 support for input registers seems to have been dropped.

Thanks!

[williamjeccles]

@canton7 on it!

[MJW911]

sorry folks, was away from emails... ive been using the modbus integration for quite a while now with no issues on my KH10.5.
master ver: 1.17
slaves: 1.012
manager: 1.13

[canton7]

Great, thanks!

[williamjeccles]

@MJW911 I can 100% confirm that after 1.18 manager my HA stopped working with input registers and I have to use the patch to switch to holding register types which means I don't have bms or workmode control currently.

I'm currently on
Master : 1.25
Slave : 1.01
Manager : 1.18

Fox R&D are looking into it also. Likely just an accidental regression that we're the first people to notice.
They've been very responsive so I'm sure it won't be long before a fix is released but will update this thread as things develop.

[canton7]

Thanks. I don't have facebook messenger on my phone, so I'll check once I'm home this evening.

resolved in latest beta version.
