Color Control GX: v1.21 Firmware released

Firmware version v1.21 for the Color Control GX has now been released.

Changelog

The changelog from v1.20 to v1.21 is:

• Fixed bug ‘Power (W) and energy readings (kWh) incorrect for parallel systems’. See below for full a description.
• Fixed bug, introduced in v1.20: after switching off a Multi via the CCGX, and then rebooting the CCGX, the Multi would no longer be visible on the CCGX. And because it was no longer visible, it was also impossible to turn it back on again.

 The known issues are:

• Support of recovery from USB sticks does not work on all sticks.
• Finding a USB-GPS might take a while.
• Reconfiguring a VE.Bus system with VEConfigure, while leaving the CCGX connected to the system, can result in kWh peaks on the VRM Portal. Note that doing this (using VEConfigure without disconnecting the CCGX) might result in many other problems too!
• The Tiles page will show ‘HUB-1’ in case there is an MPPT in the system, even when there is no HUB-1 assistant loaded into the Multi: confusing.
• When VE.Direct products (BMVs, MPPTs) are connected via USB, their device instance might change. This causes double entries in the device list on the CCGX. And it messes up the graphs in the advanced tab on the VRM. Note that this does not happen in all such installations. It might be related to long USB cables.

Full description for bug: ‘Power (W) and energy readings (kWh) incorrect for parallel systems’Affected systems:

VE.Bus systems with units running in parallel: in single phase installation (2 or more units), split-phase (4 or more units) and three phase (6 or more units).

 Description:

The reported Power (W) and Energy readings (kWh) are wrong while connected to the AC input, for example during charge and pass-through operation. The bug was in the VE.Bus firmware, and has been fixed in VE.Bus firmware version xxxx159, xxxx209, xxxx306. That firmware was released on February 17^th.

CCGX version v1.21 and newer work around this bug by checking the VE.Bus firmware version when it detects a parallel system. When the VE.Bus firmware version contains the fix for the Power and Energy readings, it does nothing special. When it detects an older VE.Bus firmware, it activates a work around:

1)      It uses the real power from each phase-master, and multiplies that with the number of slaves.

2)      It no longer reports kWh readings for the VRM solar yield and consumption tab.
