Your PETKIT fountain will not join Wi-Fi, and that is normal
- Bluetooth only: the fountain answers instantly when you are standing next to it, then stops responding the moment you leave the room.
- Nothing to select: the PETKIT app clearly knows your Fresh Element Solo is there, but the fountain never actually starts using it.
- Frozen numbers: water level, filter life and drinking records are still showing whatever they showed the last time your phone was nearby.
- No alerts away from home: no low-water or filter notification arrives while you are out.
- Stop working on your router: PETKIT lists the Eversweet Max 2 (model P4116) with a Bluetooth app connection and nothing else. There is no Wi-Fi radio in the fountain to fix.
- Remote access comes from a second device: PETKIT calls it Interconnection. A PETKIT device that is on Wi-Fi picks up the fountain over Bluetooth and passes its data to the cloud.
- Turn it on from the fountain, not the feeder: open the Eversweet Max 2 in the app and choose the master device there.
- Respect the three conditions: the master must sit within 8 metres (26 ft) of the fountain, with no obstacle blocking the signal, and it must be running the latest firmware.
Why the fountain stays on bluetooth
Owners usually arrive here after an evening of router work: splitting the 2.4 GHz band, rebooting the feeder, reinstalling the app, resetting the fountain. None of it helps, because none of it addresses what is actually happening. The fountain is not failing to join Wi-Fi. It was never able to.
There is no Wi-Fi radio in the fountain
The specification table in the PETKIT Eversweet Max 2 (Cordless) user manual lists one line for connectivity: App Connection, Bluetooth. The product page language around remote control and smart monitoring describes what the wider PETKIT system can do, not what this fountain does on its own. So the moment your phone leaves Bluetooth range, the fountain has no other way to reach you.
The relay is a radio link, not a network
Interconnection does not put the fountain on your network. Your Fresh Element Solo keeps talking to the internet over Wi-Fi, and separately keeps a Bluetooth link open to the fountain. That second link is short-range and physical: PETKIT gives a hard limit of 8 metres with no obstacle in between. A wall, a fridge or a full metal appliance sitting between the two devices is enough to break it, even though both look perfectly healthy in the app.
Once you know that, the fix stops being a network problem and becomes a placement and settings problem, which usually takes about fifteen minutes.
How to set the interconnection up so it holds
Work through these in order. Part A confirms the Solo is genuinely able to act as a master; Part B turns the link on and keeps it alive.
The Max 2 ships without a wall plug
PETKIT includes the USB cord only. A basic 5V 1A adapter keeps the fountain on mains power while you set the link up and test it.
If the issue persists: replacement options
If the fountain updates from another room but drops out again within a day, the problem is almost always where the master lives rather than how it is configured. A feeder gets moved, unplugged during cleaning, or sits one wall too far away. The devices PETKIT accepts as masters are its self-cleaning litter boxes and its smart feeders, and a litter box has one practical advantage here: it stays in one place, permanently plugged in, and is rarely carried to the sink. Putting an eligible master in the same room as the fountain is the fix that actually holds.

Advanced checks and device eligibility
Three situations come up often enough to be worth their own answers.
The app lists the feeder but the fountain data never refreshes
Seeing the feeder in the app tells you the feeder exists in your account. It tells you nothing about whether the Bluetooth link to the fountain has been established. The reliable test is the fountain's last update time: if it only ever moves when your phone is in the room, the relay has never run.
When the setting appears to be on but nothing is relayed, remove the fountain from the app and add it again while standing beside it, then set the master device once more before walking away. Re-adding rebuilds the pairing record that the relay depends on. Do this with both devices in the same room and the fountain on mains power.
Which PETKIT devices can act as a master
PETKIT's manual describes eligibility by product family rather than by listing every model, and then names the two exceptions. The table below is that statement, unchanged.
Do you actually need the interconnection?
It is worth asking honestly. Without a master, the fountain still runs its modes, still tracks drinking events, and still syncs everything the next time you walk past with your phone. What you lose is remote control and away-from-home alerts, most usefully the water-shortage notification.
If you are at home daily and the tank is a 3 L reservoir, a habit of opening the app when you feed your cat covers most of that gap. The interconnection earns its keep when you travel, when the fountain sits in a room you rarely enter, or when someone else is checking on your cat while you are away.
| Device family | Can act as master | What PETKIT says |
|---|---|---|
| PETKIT self-cleaning litter box series | Yes | Named as a supported master family in the Eversweet Max 2 manual. |
| PETKIT smart feeder series | Yes, with two exceptions | Named as a supported master family, minus the two models below. |
| Fresh Element (P512) | No | Named explicitly as not supporting interconnection. |
| Fresh Element Mini (P530) | No | Named explicitly as not supporting interconnection. |
| Fresh Element Solo (P570) | Yes | A smart feeder, and not one of the two excluded models. |
Frequently asked questions
Does the PETKIT Eversweet Max 2 connect to Wi-Fi?
No. The specification table in PETKIT's own user manual for the Eversweet Max 2 (Cordless), model P4116, lists the app connection as Bluetooth. The fountain cannot be added to your home network, and a router that does not show it is not faulty. Remote access is provided by a second PETKIT device instead.
Can a PETKIT Fresh Element Solo act as a hub for my fountain?
Yes. PETKIT's supported masters are its self-cleaning litter box series and its smart feeder series, and the two feeders it excludes by name are the Fresh Element (P512) and the Fresh Element Mini (P530). The Fresh Element Solo is model P570, so it qualifies — provided it is online, on the latest firmware, and within range.
How far can my PETKIT fountain be from the master device?
PETKIT gives 8 metres (26 feet) with no obstacle blocking the signal. Treat that as a best case in an open room. If a wall or a large metal appliance sits between the two devices, expect considerably less and plan on putting them in the same room.
Why does my PETKIT fountain show old water level and filter data?
Because the figures you are looking at were captured the last time your phone was close enough to reach the fountain over Bluetooth. Until an interconnection is running, the app has no other way to collect them, so the numbers stay frozen between visits.
Do I need the interconnection to use the fountain?
No. All the water modes, the drinking records and the on-device alerts work over Bluetooth alone. What the interconnection adds is remote control and notifications while you are away, which matters most when you travel or when the fountain sits in a room you rarely enter.
Conclusion
The frustrating part of this one is that nothing is broken: the fountain is doing exactly what its specification says, and the hours spent on the router were never going to pay off. Get the feeder and the fountain in the same room, set the master from the fountain's own page, and the remote view usually appears within minutes. If yours still refuses after that, tell us what your feeder's model label says and how far apart the two devices sit — those two details explain most of the remaining cases.
