How evaluation starts
Map the architecture
TESP reviews gateway fit, data path, security, and support needs.
Define next step
Move to technical demo, pilot planning, or a qualified commercial proposal.
Who should evaluate Sandesh?
The right conversation depends on whether you operate assets, implement projects, or bring Sandesh into customer opportunities.
Seller opportunity
Add Sandesh to automation, electrical, VFD, and industrial networking conversations
Use Sandesh as a practical Made-in-India industrial connectivity product for customers already asking about panels, drives, gateways, Modbus, remote monitoring, diagnostics, or field-device access.
Evaluate Commercial FitProof that can be inspected, not just claimed.
Sandesh credibility is supported by documented field evidence, named project context, and a Schneider Electric appreciation reference. Together, they give buyers a practical basis to review deployment history and application relevance.
Project evidence
Documentary field evidence, 2022
Petronet context
Remote valve operation across a difficult communication path.
A documented 2019 project architecture shows how Sandesh supported a 4G-based remote valve-operation requirement across a difficult river-crossing communication path.
- Remote command, valve-status monitoring, and feedback were central to the requirement.
- The architecture shows a Sandesh-enabled cellular control and feedback path with industrial protocol elements.
- Field photographs from 2021 and 2022 show the installed panels and real deployment environment.

Sandesh ecosystem
The Sandesh ecosystem connects the work around the gateway.
The Sandesh ecosystem supports commissioning, firmware management, secure access, testing, certificate generation, device-health monitoring, and Modbus data workflows.
Evaluate Ecosystem FitSend your Sandesh enquiry
Provide the essentials. TESP can review application fit and guide the next technical or commercial step.
Not necessarily. Sandesh can be evaluated as a Made-in-India industrial edge option that sits alongside existing modem, gateway, drive, and automation portfolios where the application fit is clear.
No. Sandesh should be discussed as an industrial modem / edge gateway ecosystem for remote monitoring, diagnostics, Modbus workflows, commissioning support, and last-mile field access.
Share the customer segment, site type, field devices, protocol, connectivity constraint, and what remote visibility or control is required. One concrete use case is enough to begin.
Pricing and commercial terms are discussed after TESP understands the application, project requirements, and expected partner role.
TESP confirms setup support, warranty coverage, field responsibilities, and the recommended support model based on the deployment requirements.
Available proof includes documented Petronet project context, field-deployment photographs, actual Sandesh hardware, the Sandesh Studio interface, and a Schneider Electric appreciation reference.
Sandesh is protected by two patents, reflecting the original engineering and intellectual property developed around the product ecosystem.
Bring one difficult field-connectivity problem.
TESP can map Sandesh to technical fit, deployment approach, and the right next step. The team confirms the recommended configuration, support model, warranty coverage, and commercial path for each application.
