Light Symphony Smart Timer Astronomical - App, Alexa/Google voice & dusk/dawn control

Garden Lighting That Follows the Changing Seasons

The Light Symphony Smart Timer, model LS30952STIM, adds automatic scheduling and smartphone control to a Light Symphony garden lighting system. Its astronomical clock calculates sunset and sunrise, helping the lighting follow the changing seasons without repeatedly resetting a fixed evening start time.

It is useful when you want the garden illuminated as daylight fades, with different areas following different routines. A terrace can serve evening entertaining while the approach to the house follows a separate schedule.

The Indoor Link to Your Outdoor Lighting

The Smart Timer connects to your router and communicates wirelessly with Light Symphony lighting controllers outside. The white ABS unit measures 170 x 65 x 30mm and carries an IP40 rating for indoor installation.

It belongs inside the house or another suitable dry indoor location. The outdoor controllers remain responsible for switching or dimming the connected lighting circuits.

How the Nine Timers Work

Nine independent timers provide scope to organise different parts of the scheme. The astronomical settings account for dusk and dawn through the year, while the router connection allows the clock to set automatically.

Timer settings can be managed through the app. This brings routine scheduling and everyday adjustments together, rather than requiring a separate physical timer for each lighting area.

App, Voice and Handheld Control

The Smart Timer supports the Light Symphony app and compatible Alexa or Google Assistant voice control. It can be added alongside existing handheld controls, so using a phone does not have to become the only way to operate the garden.

Its repeater function relays compatible wireless commands. Positioning still matters: walls and other obstacles affect radio coverage, so test communication with the outdoor controllers before settling on its final location.

Where It Works Best

This is the accessory to choose when an existing key fob operated system needs regular schedules, or when a new installation should offer both app and physical controls. It pairs naturally with the 4 Channel Lighting Controller for a garden divided into several circuits.

For suitable colour changing systems, its light show function can synchronise compatible LED lighting. Standard white fittings do not become colour changing simply by adding a timer.

Questions People Ask

Does the Smart Timer replace my Light Symphony controller?
No. It adds app, timer and voice control to compatible Light Symphony controllers, which still do the actual switching or dimming.

Will I need to change the timer every season?
No, not for normal seasonal changes. The astronomical clock adjusts its sunset and sunrise calculations through the year, so dusk based schedules stay more natural.

Can I still use my key fob?
Yes. A compatible Light Symphony key fob can still be used alongside the Smart Timer, so you are not limited to phone control.

Can the Smart Timer be fitted outside?
No. The LS30952STIM is an IP40 indoor unit and should be fitted in a suitable dry indoor position.
