The whole site at a glance
Every sensor on one dashboard: live value, 24-hour trend, uptime, report interval and signal bars. Fleet totals across the top show what's online, what's in alarm and how healthy the radio links are.
- Up to 250 sensors per site license, any mix of types
- Filter by type and status; sort by what needs attention
- Works in any browser on the plant network, including phones
Gas monitoring with TWA and STEL
GasWatch sensors report H2S, Cl2, ClO2, NH3, CO, O2 and LEL. SiteWatch applies A1/A2 alarm setpoints and tracks 8-hour TWA and 15-minute STEL exposure for each one.
- A1 and A2 alarms per gas, set in settings.ini
- NIOSH exposure limits where published
- For monitoring and early warning, not confined-space entry
Corrosion to ISA-71.04
CorroWatch crystal sensors are graded G1 to GX against ISA-71.04, and ER probes report metal loss rate and probe life. Thirty days of history show whether a room is getting worse.
- Copper and silver reactivity classes
- Metal-loss rate and cumulative loss
- Uptime, signal and packet history per sensor

Frequently asked
Which sensors does it work with?
Dragino LoRaWAN temperature and humidity sensors (LHT65N, LHT52, LSN50, S31 and more) plus Syon Automation's CorroWatch corrosion and GasWatch gas sensors. Any mix, through The Things Network or ChirpStack over MQTT.
Does it need the internet?
Only to reach your network server if it's in the cloud. With ChirpStack on your own network, SiteWatch runs entirely on-site. Python is included, so setup downloads nothing, and the license key is checked on the PC.
What happens after the 14-day trial?
Live monitoring pauses until you enter a license key. Demo mode, your settings and the daily CSV logs keep working, and nothing is deleted.
What's the difference between the editions?
All three include every feature. Starter covers 10 sensors, Plant 50 and Site 250. Need more than 250? E-mail sales@syonautomation.com.
Is it a subscription?
No. It's a one-time purchase that keeps working forever. The first 12 months of updates are included; after that, the optional yearly renewal keeps you on the newest version.
Can GasWatch replace our gas detectors?
No. GasWatch readings are for monitoring and early warning. They do not replace personal gas detectors or certified gas detection for confined-space entry.
