Transmitting an alternative light command for a longer period

An electronic device for causing one or more lighting devices to render a light effect, the electronic device comprising at least one processor configured to:

• determine a first part of said light effect to be rendered by said one or more lighting devices during a first period based on an original first light command,
• determine a likelihood that an original second light command specifying a second part of said light effect to be rendered by said one or more lighting devices during a second period, succeeding said first period, will not arrive at a destination of said original second light command is above a threshold,
• determine said second part of said light effect, and
• determine and transmit an alternative first light command, instead of the original first light command, in dependence on said determined likelihood and based on said determined second part of said light effect, said alternative first light command being determined based on said determined first part of said light effect and said determined second part of said light effect and said alternative first light command specifying a portion of said light effect for both said first period and said second period.
