Superior MegaHub is a hybrid control panel that works with up to 999 Fibra and Jeweller devices.
Increasing the limit to 999 devices requires system improvements on both the hub and device sides. Therefore, upgraded firmware versions have been developed for Fibra and Jeweller devices.
Devices manufactured with upgraded firmware have the “999 ready” label on their packaging. This means that you can add up to 999 devices to the hub without restrictions.

Devices manufactured earlier that do not have the “999 ready” label on their packaging and that support the DFU feature can download and install the upgraded firmware remotely. Once the upgraded firmware is installed, you can add up to 999 devices to the hub without restrictions.
Devices manufactured earlier that do not have the “999 ready” label on their packaging and do not support the DFU feature remain on legacy firmware. Such devices can still be added to Superior MegaHub, but the device limit is reduced to a maximum of 250.
Thus, Superior MegaHub supports both devices with upgraded firmware (i.e., marked “999 ready” and updated via DFU) and devices with legacy firmware. However, no more than 250 devices with legacy firmware can be added to the hub. The remaining devices within the 999 limit must have upgraded firmware.
For example, you added 100 devices with legacy firmware and 100 devices with upgraded firmware to the hub. The number of available device slots is now 799. You can add up to 150 devices with legacy firmware and up to 649 devices with upgraded firmware to the available slots.
If you try to add more than 250 devices with legacy firmware to the hub, you will receive a warning that the limit has been reached.

Superior MegaHub running OS Malevich 2.37 supports up to 250 Jeweller devices, including those with upgraded and legacy firmware. This is a temporary limit that will be removed in future updates.
