Do smart toilet seats, bathroom heaters, and water heaters need to be connected to WiFi? The bathroom signal is the worst in the whole house. After installing three things, only one is worth it

the National Day holiday, I added things to the bathroom: I replaced the electric water heater with WiFi, casually bought a smart bathroom heater, and the toilet seat was stocked up by my wife before Double 11. But out of the three, two were matched with the network, and I was so frustrated, I went back and forth for half the night. The reason is simple—the bathroom is the room with the worst signal in my home, bar none.

first understand: why is the bathroom a graveyard for whole-house WiFi

the test about blind spots I walked around the room holding my phone, and I still remember the numbers: living room -44, dining room -55, kitchen -74, bathroom -79. The more dBm is negative, the weaker the signal becomes. -79 is a level even vacuum cleaners dislike—it's a 'can connect but drops at any time' scenario.

There are three reasons why

bathrooms are miserable. First, location: the router is in the living room TV cabinet, separated by two walls from the bathroom, or at the end of the corridor, which is naturally far away. Second, the wall materials have been upgraded: behind the tiles is a cement mortar layer, which is denser than ordinary partition walls, and signals are both absorbed and reflected; Above the head, there's an integrated metal ceiling frame and a room full of water pipes, and metal is even more unscrupulous for 2.4G. Previously, I wrote about smart door locks where I mentioned that metal security doors are signal black holes. The same logic applies to the tiled wall in the bathroom, except the door blocks one gap, while the wall covers the entire side.

a hidden knife while showering: the whole room is filled with steam. 2.4GHz happens to be the frequency water molecules love to absorb—microwaves heat food thanks to the frequency of water gnawing. Normally, it's -79, and once you turn on a hot shower, the signal drops even more. So when smart devices are soaked in the bathroom, it's like being the farthest from the router, the hardest to penetrate walls, and even covered in water outside. If the network fails, it's really not the device's fault.

Water Heater: The only one of the three that you can keep your eyes shut and connect with

to put the conclusion here: among the three, water heaters have the highest networking value, and no one can persuade you to do so.

core is the laptop billing account. A 60-liter electric water heater runs 24 hours a day, providing 2.5 to 4 kWh of electricity per day—boiling tap water from 15 degrees to 60 degrees takes about 3 degrees. The rest is the loss from repeated heating during insulation, and the worse the energy efficiency rating, the greater this aspect becomes. Switch to an app for appointments: on the way home at 6 o'clock, or set it to automatically heat at 18:00 on weekdays, so when you get home, it's hot—1 to 2 kWh a day. With each round trip, the daily difference is one or two degrees, about thirty degrees a month, about twenty yuan. Over 200 yuan a year, that's enough to buy a remote control version for the toilet seat. about electricity bills I measured the line of devices in the weak current box with a metering socket, and I only covered up the water heater bill this time.

if your home has peak or off-peak electricity rates, you can move the heating to the off-peak hours at night, and you can cut your electricity bill even more. This app lets you set it all up. There are also two handy benefits: during the days you go out during the National Day holiday, you can just turn off your phone and cut off the power in the app, so you don't have to worry; Install one at the elderly woman's home and teach her to press a button, which is more worry-free than running it every day and worrying about it every day.

the water heater is actually the best of the three. It hangs on the wall about 1.8 meters tall, with the antenna facing outward, no ceiling covering overhead, and my home network installation passes in one go. The next post about the bathroom bomb will be a negative example.

bathroom heater: networking is useful, but value depends on the person

I bought the Smart model from Aop, which can schedule heating via the app: set to automatically turn on at 6:45 AM, and getting up at 7 AM to enter the bathroom is already hot. In winter, just a few dots in the living room half an hour before bathing the kid—they don't get fluttered when you pick them up, but this one really works.

to be honest: the bathroom is only three or four square meters, and it only takes two seconds to press the wall switch at the door. Remote control can basically be replaced by "timing," which is a machine-local function and runs without internet connection. What really keeps me connected is the voice command—when your hands are full of foam, just say 'Xiao Ai turns off the heater' is much easier than reaching out to press a panel full of water droplets. This is a real experience point.

pit also hit a trap: the bathroom heater is installed in the integrated ceiling, the metal panel acts like a big pot lid, and the antenna is directly plugged inside. My first device had an app that didn't work after installation. After checking the manual, I found the antenna needed to be pulled out of the mounting board, so I fixed it again to stabilize. Before buying, ask customer service if the antenna can be pulled out. If you can't ask, scroll through the three words 'can't connect' in the negative review section.

Toilet Seat: Don't Spend More on the WiFi Version

wife's toilet seat is the WiFi version, which costs 80 yuan more than the Bluetooth remote version. After installing it for a month, I opened the app twice—once for network setup, and second time to see what other features it had, but never opened it again.

break down the functions: flushing, seat rim heating, water and air temperature adjustment, remote control—none require a grid. The WiFi version adds remote warm-up (who warms up the toilet at work), water usage statistics (just a glance and you get tired of it), and voice interaction (commands like "I need to use the bathroom" are too embarrassing for anyone at home). The essence of the app is to replace the remote control, which itself doesn't require internet.

worse, the location is the toilet at the innermost corner of the bathroom, right next to the pipe well—-79dBm is exactly what it means. To keep these useless features stuck in the worst signal in the house for years and repeatedly reconnect, each reconnection of the WiFi module consumes more power than an hour of standby—it's a case of paying for a painful experience. The conclusion is simple: buying the remote control saves money and signals as well.

signal is insufficient, three levels of remediation are done in sequence

first tier is zero yuan, moving equipment position. Don't stick the water heater antenna against a dead wall; the bathroom heater antenna should be pulled out of the clip board. As for the toilet seat, forget it—there's no choice about the position. You also need to choose the right timing for the setup—after showering, the water vapor has cleared before installation, which increases the success rate. about network configuration failure I wrote about smart devices only recognizing 2.4G, and my home router has dual-band integration. First, I split the two bands and name them for pairing, then reassemble them after pairing. I've written about this method more than once the method of disassembly.

second tier is 100 yuan, plus nodes. Mesh sub-routers or old routers can be replaced with repeaters and hung on corridor walls—not in bathrooms, where water vapor can rust the circuit; Place it in the corridor, just go through a door and you'll arrive. The principle for placement is simple: place it at the edge of the main router coverage, next to the bathroom. How exactly do you find this location? Mesh the placement article I tested eight points, just follow the instructions.

third gear, accept it. The toilet seat is fully functional even without internet connection, so you can physically declutter directly, and the router device list is much cleaner. dozens of smart devices in the whole house, I've the capacity ledger separately. The bathroom is the last piece of the puzzle—the fewer the less, the more worry.

more important than signals: water and electricity

bathroom crowded with smart devices, first run through the sockets. Wherever the showerhead can splash, use a splashproof box (the kind with a cover). The water heater socket should be set higher and farther from the side of the showerhead. This is not a matter of formality, but a bottom line.

the circuit in the distribution box that manages the bathroom is leak protection, the one on the panel that says "once a month." If you really press it once, it won't go down or won't close after pressing, so call an electrician immediately. When smart devices multiply and the leakage protection trips, the troubleshooting approach is simple: unplug each new one by one before closing the switch. This is how my bathroom heater trips the first time—the neutral and live wires are connected inverted, which has nothing to do with networking.

Here's the order for finishing: first stand in the bathroom and check the signal—install anything below -75, fix it outside -80 before buying; The first water heater is connected, and the electricity bill dividend starts that day; Check if the bathroom heater has voice and timer habits at home; The toilet seat is done with the remote control version. When it comes to smart bathroom devices, the ranking of whether they're worth connecting to the internet is never about how smart they are, but about how many functions remain after the internet is cut off.
