Sonoff S61s Outdoor Review: The IP44 Schuko Plug That Takes Matter Into the Garden
The Sonoff S61s Outdoor (S61STPF-PM-O) is the outdoor version of Sonoff's Schuko Matter plug: an IP44 body with a hinged cover over the socket, specified from -20C to 50C, rated 16A across 100 to 240V for a 3840W ceiling that comfortably covers a pool pump, an irrigation controller or a patio heater. Matter over Wi-Fi is what makes it worth the step up from a dumb timer, because scanning the code on the body drops it into Apple Home, Google Home, Alexa, SmartThings or Home Assistant with no Sonoff bridge in the path, and owners who paired it into Apple Home and Home Assistant describe that part as quick. The metering is the other half: live voltage, current and power, historical charts, exportable data and a cost figure built from your own tariff. The friction is real but narrow, a body bulky enough to block the lid of some garden socket boxes, scheduling in the eWeLink app that several owners found unintuitive, and 2.4GHz Wi-Fi that one owner saw drop out.

- Energy monitoring with historical charts, data export and cost tracking on your own tariff
- Overload cut-offs on current, voltage and power thresholds you set yourself, plus overcharge protection
- Splash-proof physical button and LAN control, so it still switches without the cloud
- Owners describe solid build, effective sealing and a body that stays cool under sustained load
- Two year warranty
Cons
- Bulky body that can stop the lid of a garden socket box from closing
- Scheduling in the eWeLink app is unintuitive and the box ships with minimal instructions
- 2.4GHz Wi-Fi only, with no 5GHz band, and one owner reported unexpected dropouts
- No bidirectional metering yet, so exported solar power is counted as consumption
- Energy statistics appear only in SmartThings and Home Assistant, and need firmware 1.0.6 or later
- Single socket, no USB charging ports, and no Zigbee, Thread or Z-Wave radio
Who is the Sonoff S61s Outdoor for?
This is the plug for the sockets that live outside the house, on the terrace wall, in the garden or beside the pool, where an indoor plug has no business being. The IP44 rating and the hinged cover are the reason it belongs there, and Sonoff is explicit that the load's own plug has to carry an equivalent rating and that the pair should sit in a waterproof enclosure. The jobs owners describe are exactly the ones the rating implies: pool filtration run remotely while away, garden string lights switched on in the evening, a pump on a schedule. The second audience is anyone who has already picked a smart home app, because the plug joins over Matter and behaves the same in Apple Home, Google Home, Alexa, SmartThings and Home Assistant rather than forcing another vendor app into the routine. And because the 16A rating is a real appliance rating rather than a lamp rating, the load in question does not have to be small.
What buyers love
The recurring praise is that it does the job it is bought for and does it outdoors. Owners describe the build as solid, the sealing as effective in real weather and the body as staying comfortably cool after days of continuous work under load. The Matter path draws the most consistent approval: one owner set it up quickly in Apple Home and pointed out that Matter makes it far more useful than plugs that can only be driven from their maker's own app, and another paired it straight into Home Assistant over Matter without trouble. The remote control itself is described as responsive, with app commands acting immediately. Beyond switching, the combination that keeps coming up is scheduling plus consumption: being able to run the pool pump on a routine, turn it off from anywhere and then see what it drew is what several owners say justifies the plug over a mechanical outdoor timer.
What to know before you buy
The most concrete complaint is physical. This is a tall plug, and one owner found that the shape and length stopped the flap of a garden socket box from closing over it, so it is worth measuring the enclosure before ordering. The second is the app: the eWeLink scheduling screen defeated one owner completely and was called laborious or less intuitive than rival apps by others, and the box ships with very little printed guidance. Pairing is usually quick but not always: one owner had to enable IPv6 on the router before Matter commissioning would complete, which is documented nowhere. The radio is 2.4GHz 802.11 b/g/n only, normal for the category and generally good for range through masonry, and one owner reported unexpected dropouts that made scheduled loads unreliable. Two limits come off the spec sheet rather than the reviews: there is no bidirectional metering yet, which Sonoff lists as a planned firmware feature and which means a plug shared with a balcony solar setup reads exported power as consumption, and energy statistics only surface in SmartThings and Home Assistant among the Matter platforms, on firmware 1.0.6 or later. It is one socket, with no USB ports, and it carries no Zigbee, Thread or Z-Wave radio, so it adds nothing to a mesh.
Is the Sonoff S61s Outdoor worth it?
For a budget-tier plug the sheet is unusually full for outdoor duty: IP44 sealing with a covered socket, a -20C to 50C operating range, an appliance-grade 16A and 3840W ceiling, user-set current, voltage and power cut-offs, overcharge protection, retained and exportable metering with tariff-aware costing, a splash-proof physical button, LAN control that keeps the app working when the cloud is not, and a two year warranty. Against a mechanical outdoor timer the metering and the remote control are the whole argument; against the indoor Type F model in the same family, what you are paying for is the sealing, the wider temperature range and the cover, not different software. What it will not do is fit every garden socket box, and the eWeLink scheduling is the part most likely to cost an evening. If the plan is to put a pump, a set of lights or a heater outside on a schedule and know what it costs to run, this covers it without adding a hub to the shelf.
Frequently asked questions
Can the Sonoff S61s Outdoor be left outside in the rain?
Yes, within its rating. The housing is IP44, which covers dust and splashing water from any direction, and there is a hinged cover over the socket itself. Sonoff specifies it from -20C to 50C, and asks that the connected device's own plug carry an equivalent protection rating and that the pair be installed inside a waterproof box.
Does it need a Sonoff hub or bridge?
No. It is a Matter over Wi-Fi device that talks to the router directly, so no Sonoff gateway sits in the path. You do need a Matter controller for the ecosystem you use, such as a HomePod or Apple TV for Apple Home, a Nest speaker or display for Google Home, a compatible Echo for Alexa, or a SmartThings or Home Assistant setup. Sonoff's own eWeLink app is a second pairing route for anyone who prefers it.
Which smart home platforms does it work with?
Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, all over Matter. Sonoff documents app remote control, voice control and smart scenes on all five, and Matter is multi-admin, so one unit can belong to several of them at the same time. Power and energy consumption data is additionally exposed in SmartThings and Home Assistant from firmware 1.0.6.
How much power can it switch?
It is rated 16A across 100 to 240V, which works out to a 3840W maximum load. On a 230V European supply that covers a pool pump, an irrigation pump, a patio heater or an outdoor lighting run, and you can set your own current, voltage and power thresholds so the plug cuts the supply before a limit is crossed.
What energy data does it record?
Live voltage, current and power plus device runtime and total consumption, shown as historical charts that can be reset when the appliance changes and exported for further analysis. It also converts the consumption into money using a currency and tariff you configure. Bidirectional metering, for measuring solar export, is not available yet and is listed by Sonoff as a planned firmware update.
Does it work on a 5GHz network?
No. It supports 802.11 b/g/n on 2.4GHz only. If the router broadcasts both bands under one network name it can help to split them while pairing, and at least one owner needed IPv6 enabled on the router before Matter commissioning would complete. Bluetooth is used for the Matter handshake and for Sonoff's Proximity Mode, not for everyday control.
