Market Reality: Industrial Zigbee Is Bigger Than You Think
Before diving into products, here’s a number that might surprise you: the global Industrial Zigbee Gateways market was valued at $936 million in 2024 and is projected to reach $2.5 billion by 2035, growing at 9.3% annually . Overall, the Zigbee market hit $4.9 billion in 2024 and is expected to reach $8.63 billion by 2033 (CAGR 6.5%) . Another research firm puts the 2024 market at $13.75 billion, forecasting $26.54 billion by 2032 .
The industrial automation part is really big for Zigbee applications. It makes up 34.6 percent of them which’s the biggest use. North America has the most, with 34.2 percent of the market share, for automation and Zigbee applications.
Why does this matter to you? Because when you pick industrial Zigbee products, you’re choosing a technology with real market traction, mature standards, and years of field deployments behind it.
Who This Guide Is For
You’re an engineer, integrator, or facility manager who has already decided Zigbee makes sense. Now you need to pick the actual hardware. You don’t want a 50‑page catalog or a list of every product on the market. You want to know what actually works in industrial environments—and what fails when it gets cold, wet, or noisy.
This guide cuts through the marketing. It starts with three questions to narrow your needs, then shows you the products that handle the real world.

Before You Buy: Three Questions to Ask Yourself
Every list of the products is not helpful unless it has products that you need. Take two minutes to answer these questions:
1. What am I connecting to Zigbee?
- Is it a sensor with RS485 output?
- A PLC with RS232?
- A controller that needs Ethernet?
The equipment you already have will tell you what kind of Zigbee device you need.
2. Where will I put the Zigbee device?
- Will it be in a room where the temperature’s always the same?
- Will it be outside where it is very cold in the winter and very hot in the summer?
- Will it be in a room with concrete walls and metal shelves?
Where you put the Zigbee device will tell you what kind of temperature range and enclosure it needs.
3. How far does the data from the Zigbee device need to travel?
- Does it need to go to another room?
- Does it need to go to another part of the building?
- Does it need to go around a campus?
How far the data needs to travel will tell you if you need radios or just a simple connection.
Write down your answers to these questions, about Zigbee. They will help you make choices when you buy Zigbee products.
| Question | My Answer | Implication |
|---|---|---|
| Device interface | __________ | Need RS232/485/Ethernet model |
| Environment | __________ | Need commercial/industrial rating |
| Distance | __________ | Need standard/long-range model |
| Power available | __________ | Mains vs battery affects device choice |
Decision Flowchart: Visual Guide to Choosing
The Two Products That Cover 90% of Industrial Zigbee Needs
Here is the thing about Zigbee: most applications fall into two categories.
Category 1: You have old equipment with serial ports that needs to go wireless.
Your old PLC, your flow meter, your temperature controller—they’ve got RS232 or RS485 ports. They work fine. You just don’t want to run cable to them.
For this you need a Zigbee to converter.
It sits next to your equipment grabs the data and beams it over Zigbee.
Category 2: You need to collect data from multiple Zigbee devices and get it onto your network.
All those wireless sensors are great. The data has to go somewhere. Your Supervisory Control And Data Acquisition system, your cloud dashboard, your local server.
For this you need a Zigbee to Ethernet gateway.
It sits at the top of your network talks to all the Zigbee devices and presents the data as TCP/IP packets your systems understand.
One company that builds properly with industrial specs. Is Valtoris.
Their VT-ZB700 and VT-ZB701 cover these two jobs. Do it well.
Product Deep Dive: Valtoris VT-ZB700 (Zigbee to Serial Converter)
What it is: A box that takes any device with RS232, RS485 or RS422 and makes it a Zigbee node.
Who it is for: Anyone with existing equipment who wants to cut the cables.
The specs that matter:
| Parameter | Value | Why It Matters |
|---|---|---|
| Interface | Ethernet 10/100M | Connects to your existing network |
| Zigbee Role | Coordinator | Manages the whole network |
| Protocols | TCP/UDP/HTTP/DHCP/DNS | Plays nice with IT standards |
| Operating Temp | -40°C to 85°C | Same ruggedness as the VT-ZB700 |
| Power Input | 9-24V DC | Consistent with industrial power |
What you can achieve with this hardware:
- Network Coordinator: The brain of your mesh network, it automatically routes traffic and allows other Zigbee nodes to easily join the cluster.
- Protocol Gateway: It actually converts Zigbee payloads to standard TCP/IP packets. So, your existing SCADA or monitoring software will see it as just another standard network device on the LAN.
- Virtual COM Port Integration: The included Vircom software allows your Windows PC to map a direct virtual serial connection to the remote nodes. Your legacy software will keep polling COM ports unaware that the physical cables have been replaced by a wireless bridge.
The honest part: The VT-ZB701 does a lot. That means there are configuration options. You’ll need to decide whether it runs as TCP server, TCP client, or UDP. For most users, TCP server on port 502 (Modbus) is the right answer. The web interface walks you through it, but it’s not a single-button setup. The payoff is flexibility—it fits whatever system you already have.
Which One Do You Need? A Simple Decision Table
| Your Situation | What You Need | Why |
|---|---|---|
| One serial device at location A needs to talk to one serial device at location B | Two VT-ZB700s | Configured point-to-point, they act like a wireless cable |
| Multiple serial devices across a site need to send data to a central server | VT-ZB700s + one VT-ZB701 | VT-ZB700s collect device data; VT-ZB701 aggregates and sends to server |
| You have existing Zigbee devices and need to get their data onto Ethernet | VT-ZB701 | Acts as coordinator and gateway in one |
| Outdoor installation with extreme temperatures | Either model | Both rated -40°C to 85°C |
| Noisy electrical environment (near motors, drives) | Either model | Metal enclosure and DSSS spreading reject interference |
Real‑World Setup Examples
Example 1: Plastics Factory – 15 Temperature Controllers
The situation: A plastics plant had 15 temperature controllers scattered across the floor. Each had an RS485 port. Running cable would cost thousands and require production shutdowns.
The solution: A Zigbee‑to‑serial converter at each controller. One Zigbee‑to‑Ethernet gateway in the control room. All 15 controllers appeared on the SCADA screen within one afternoon.
The result: No cable runs. No shutdowns. Every temperature reading visible in real time.
Example 2: Cold Storage Warehouse – 20 Temperature/Humidity Sensors
The situation: A massive cold storage facility needed temperature and humidity readings from 20 locations. Running wires was impractical—the racks move, and the space is huge.
The solution: Zigbee‑to‑serial converters connected to each sensor, configured as routers. They formed a mesh network—if one sensor couldn’t reach the gateway directly, it routed through another. A gateway in the office collected all data and sent it to the building management system.
The result: If a forklift blocks one sensor, the mesh routes around it. Reliable data with no wires.
Example 3: Remote Pump Station – 800 Meters from Control Room
The situation: A water utility had a pump station 800 meters from the control room. The pump had an RTU with RS232 output. Laying fiber was expensive; digging was a nightmare.
The solution: Two Zigbee‑to‑serial converters configured point‑to‑point. One at the pump, one at the control room.
The result: 800 meters is well within the 2000‑meter open‑air range. Data flows like there’s a cable—but there’s no cable.
What About Zigbee Products?
You will find a lot of other Zigbee devices out there. There are plugs, light bulbs and sensors. They are fine for homes and offices.
For applications you need to ask some tough questions.
- What is the temperature range? If it does not say it can handle -40°C to 85°C then it is not for use.
- What is the enclosure made of? Plastic is not good because it can crack, melt and let in interference. Metal is better. It costs more.
- What kind of power supply does it need? 5V USB is for charging phones. Real equipment needs 9-24V DC.
- What about the range? When they say “up to 100 meters” that usually means it works perfectly with no obstacles. You need to look for the specs, like transmit power and receive sensitivity.
According to CSA-IOT (formerly the Zigbee Alliance), certified Zigbee devices meet interoperability standards, but industrial applications require additional ruggedness not covered by basic certification.
The Valtoris products are good because they can handle all these things. That is why they are on this list.
The 5-Point Industrial Mesh Assessment Matrix
Before you order, run through this:
- Device interface — RS232, RS485, or Ethernet? Match the converter type.
- Environment — Indoor controlled, or outdoor/unheated? Spec the temperature range accordingly.
- Distance — Short range (one room) or long range (buildings apart)? Mesh networking handles long distances.
- Existing Zigbee devices — Do you already have sensors that need to join? Ensure PAN ID and channel compatibility.
- Power availability — 24V panel supply, or need battery? Most industrial devices run on 9–24V DC.
The specs exist for a reason. Use them to avoid buying consumer gear that fails in industrial conditions.
📐 Engineering Standard Callout
Warning on Consumer Zigbee: Devices lacking a true industrial wide-temperature rating (-40°C to 85°C) will violate basic IEC 60068 (Environmental Testing) guidelines when placed in outdoor control cabinets. Above 60°C, consumer-grade RF chips experience severe thermal throttling, leading to dropped mesh nodes and SCADA polling timeouts.
Final Take
“Best” depends on what you need.
- If you’re connecting serial equipment to Zigbee, VT-ZB700 is the tool.
- If you’re collecting data from multiple Zigbee nodes and getting it onto your network, VT-ZB701 is the tool.
- If you need both—and most industrial setups do—you need both products working together.
The industrial specs matter. The metal cases matter. The wide temperature range matters. These aren’t features you pay extra for; they’re what separate gear that lasts from gear that fails.
Start with your three answers: what you’re connecting, where it’s going, how far it needs to reach. Then pick the Valtoris products that match. You’ll have a Zigbee network that just works, for years, without drama.
💬 Field Engineer Insight: “We spent weeks chasing ‘ghost’ connection drops in our water treatment plant using cheap smart-home Zigbee hubs. The day we swapped them for metal-cased, 24V-powered industrial gateways, the network stabilized entirely. Stop paying engineers $150/hour to troubleshoot $50 consumer hubs.” — Independent SCADA System Integrator

Frequently Ask Questions
Q1: My factory already has a heavy 2.4GHz Wi-Fi infrastructure. Will the Zigbee network suffer from interference?
A: This is a common concern as they both use the 2.4GHz band. But Zigbee (IEEE 802.15.4) adopts DSSS (Direct Sequence Spread Spectrum) for strong anti-interference. More importantly, as an engineer you can configure our Zigbee gateways to work on specific channels (channel 15, 20, 25, or 26) that perfectly fill in the “gaps” between the standard Wi-Fi channels (1, 6, 11) without data collision.
Q2: The specs say “long range,” but my PLCs are mounted inside heavy steel electrical cabinets. Will the signal penetrate?
A: RF signals do not penetrate solid steel well. If your VT-ZB700 converter is housed inside a metal control panel, you must use an external antenna. We supply antennas with magnetic bases and extension cables, allowing you to route the antenna to the outside of the cabinet. Once outside, the mesh network handles the rest, automatically routing data around heavy machinery.
Q3: For my remote telemetry project, should I use Zigbee or LoRa?
A: It depends on the distance and density of nodes. Zigbee is a good fit for high density, multi-node mesh networking within a single site or plant (generally up to a few kilometers line-of-sight), and provides lower latency. If you have to send small packets of data over tens of kilometers (think agricultural monitoring or smart city sensors), check out our [Industrial LoRa Wireless Modules].
Q4: How secure is the Zigbee mesh? Can unauthorized devices sniff our serial data?
A: Industrial Zigbee deployments are very secure and IT friendly. The network uses AES-128 encryption in hardware. A rogue device can’t just “eavesdrop” or jump onto the mesh. It has to be provisioned with the right PAN ID (Personal Area Network ID) and the corresponding encrypted network key that is set on your central VT-ZB701 coordinator.
