Managing Multiple Phones Without a Server: How Local Deployment Works

Last winter a friend who runs a studio came to me. He was about to expand to twenty phones and asked which server to buy.

I asked how many he was running. Six, on an old computer, and it had stayed steady. The computer stayed on with the phones.

He thought more phones meant a server, because other people talk about cloud control. I have heard the same thing several times. A lot of people buy a server after hearing that someone else moved to the cloud.

When a server is needed

Devices sit in device rooms in different cities. You are in the office and need one place to check status and send tasks. The phones are not beside you, so a local setup cannot reach them.

Agency work is the same. The client’s devices stay on the client’s side. You only have remote access, so the route is cloud networking.

Both cases are devices you cannot reach. When the phones are in the studio and one computer can connect them, monthly rent, maintenance, network setup, and sending data off your machine are costs many small teams do not use.

How a local setup is wired

One computer, one workstation program, and anywhere from a few phones to a few dozen.

Install the iEasyRun AI workstation on the computer and the matching program on each phone. On the same LAN, or over a USB cable, they can talk to each other. Task scheduling, execution records, assets, and screenshots all stay on that computer. Nothing goes through a third-party server.

Pick the connection by phone type:

Phone type	Connection	When it fits
iPhone	USB cable	You want the steadiest link, and you need mirroring on screen while you watch
iPhone	WiFi	You do not want a cable, and the phones can sit wherever there is room
Android	WiFi	The phone stays in a pocket and the computer sends the tasks
HarmonyOS	USB cable	A HarmonyOS phone attached to the computer

The four setups are compared on the installation selection page. Pick by phone and by the space you have.

After install, check three things. The workstation home page opens. At least one phone shows as online on the devices page. You can send that phone an instruction from the conversation page. Once those three work, the rest is adding devices.

How many phones, and when to move to the cloud

There is no fixed software limit. How many you can carry depends on the ports, the network, and how heavy the tasks are.

With phones on cables, a computer usually has four to eight native USB ports. Extra phones go through a hub. A hub without its own power starts dropping connections after a few phones are plugged in. Once the count grows, use a hub with its own power supply, and spread the phones across different USB controllers.

Phones on WiFi hit a limit on how many connections the router can hold at once. A consumer router carrying dozens of devices often refuses a new connection, or reconnects over and over. At that size, use enterprise gear, or split the devices across several networks.

Plain taps and typing are fine for fifteen or twenty phones on an ordinary computer. If every phone also needs live mirroring and screenshot recognition, the load multiplies and the number you can carry drops.

Load-test with your own tasks. Run ten phones and watch whether the CPU and memory curves stay flat. If they stay flat, add more. If the curve bends, stop before the bend.

Local falls short in three cases.

The devices are spread across several sites. Machine rooms in different cities, nobody on site, and a local setup cannot reach them.

Several people need to watch the same devices at once. A local workstation runs on one computer, so working together means sharing that machine. On the cloud, people can open a browser under separate accounts.

You need tenant isolation. If you are an agency and you rent grouped devices to different clients, and each client’s data must stay hidden from the others, a single local machine cannot do that.

Outside those three, most people managing around a dozen phones are fine on a local setup.

Screenshots, accounts, and business records stay on your own machine. The software is free, and there is no monthly server bill. Saved workflows run locally, so an outage does not send you out to call an external service. The data side is covered in phone automation data security.

To check the devices you have to be at the computer, or at least leave that computer on. Checking status on a trip, without the computer, is outside what a local setup can do.

If the computer fails, the tasks stop. The cloud can keep spare nodes. Locally there is one machine, and a hardware failure stops the work directly.

Adding devices means adding computers, hubs, and network gear. Those are hardware costs.

If those costs are acceptable, local is the cheaper route. If they are not, you are at the size where the cloud fits.

How to keep many devices straight

Once the count grows, what you watch is which phone is online, how far a task got, and which phone failed.

Write aliases you can read. “Sales 1” and “test phone A” in the list are easier to find than a string of random device ids.

Group by the work. By category, by model, or by purpose, as long as you can pick the right group at a glance when you send a task. Dispatching a batch by group is faster than ticking phones one by one, and you tick the wrong one less often.

An offline device can only be viewed. It cannot run. Confirm the target is online before you dispatch. If it shows offline, go back to the install page and check USB, WiFi, the phone-side program, and the workstation.

He did not buy a server. The money went to a better computer and a hub with its own power supply. The twenty phones have been running for more than half a year. He said later that how far the devices are from you decides the server question more than how many phones you have.

If the phones are within reach, try one first from the installation selection page. The software is free. You can test the idea before you spend money on a server.
