How Automatic Wind and Rain Protection Works
buyer worried about awning damage in bad weather when away
Leaving an awning extended and unattended in a sudden gust is one of the more common ways they get damaged, and wind and rain sensors exist specifically to catch that situation before it becomes a bent arm or torn fabric. Here's roughly how they work and what they can and can't do.
How a wind sensor actually measures gusts
A wind sensor typically uses a small rotating anemometer or a vibration-based sensor mounted on the frame to detect wind speed continuously while the awning is extended, sending a signal to automatically retract it once a set threshold is crossed.
Setting sensitivity correctly
Sensitivity is usually adjustable, and setting it too low means the awning retracts unnecessarily in light breezes, while setting it too high risks leaving it out in conditions that could genuinely cause damage. An installer can help calibrate this to a garden's typical exposure rather than a generic default.
Rain sensors and their limits
Rain sensors typically detect moisture on a small sensor pad and trigger retraction, useful for protecting fabric from sustained heavy rain, though light drizzle doesn't always trigger a response and isn't necessarily something the fabric needs protecting from anyway.
- Wind sensor
- measures gust speed, retracts above set threshold
- Rain sensor
- detects moisture, triggers on sustained rainfall
- Sensitivity
- adjustable to suit typical local exposure
- Manual override
- usually still available alongside automatic function
Why exposed gardens benefit most
Gardens on higher, more exposed ground toward the Pennine edge, or open sites without much wind break, see more frequent and sudden gust changes than sheltered urban gardens, making automatic wind retraction a genuinely useful feature rather than a nice-to-have extra.
What sensors don't replace
Automatic sensors reduce risk but don't eliminate it entirely, particularly in genuinely severe weather where manual judgement about retracting or removing fabric altogether is still the sensible approach. They're a safety net, not a substitute for common sense in extreme conditions.
Common questions
Do all electric awnings come with sensors as standard?
Not always — some are motor-only with sensors as an optional extra, so it's worth asking specifically if this matters to you.
Can sensors be retrofitted to an existing awning?
In many cases yes, provided the motor system is compatible, though it's worth checking with your installer for your specific setup.
Will a wind sensor retract the awning too often in a normal breeze?
Not if sensitivity is set appropriately for your location, which is why calibration during installation matters rather than leaving a generic default.
Does a rain sensor stop the awning getting wet at all?
No — it retracts the awning once sustained rain is detected, but some initial wetting before that trigger is normal and expected.
In short
Wind and rain sensors automatically retract an awning in worsening conditions, and are especially useful in exposed, unattended gardens.
