No, although the solar tracking works better with a consumption meter.

If your solar system has a consumption meter, you can see your household consumption and grid imports and exports. Without a consumption meter, you can only see solar generation.

If a consumption meter is present Charge HQ can divert the excess solar to EV charging. For example, if you turn on your oven, Charge HQ will reduce the EV charging power to avoid importing from the grid.

Without a consumption meter Charge HQ can simply adjust the EV charging power to match the solar generation. So if you turn on your oven, Charge HQ won't know and won't reduce the EV charging power. The settings do allow reserving a certain amount of solar power for household consumption.
