Made in India · Indian OEM · DPIIT-recognised
Krionix designs and manufactures IoT hardware in Harihar, Karnataka, with the AutoStack™ cloud platform on top. We connect the water meters, energy meters and electrical assets you already have. No replacement is needed.
Made in India · Atmanirbhar Bharat
Krionix devices are not rebadged imports. Our own team in Harihar, Karnataka handles every stage, from the first schematic to the field visit.
Problem study, sensing method and system architecture
Schematics, PCB layout and enclosures
Embedded firmware, OTA updates and the AutoStack™ platform
Assembly and testing at our Harihar facility
Every unit is tested for communication and readings before dispatch
Our own engineers install, commission and maintain
We design and make our own products, so we control quality, can customise quickly for Indian utilities, and support devices for their whole life.
Our retrofit technology is protected by Indian patent applications 202541062777 and 202541075290.
Our own team handles hardware design, firmware, cloud software, installation and after-sales service.
We are a DPIIT-recognised Startup India company and an Udyam-registered MSME, aligned with Make in India and Atmanirbhar Bharat.
What we solve
We build the device, the firmware, the connectivity and the dashboard ourselves. Pick a solution to see how data flows from the field to your screen.
Retrofit AMR for existing mechanical meters, plus bulk ultrasonic metering on the distribution main. Comparing bulk inflow with consumer usage shows exactly where non-revenue water is lost.
Turn existing electricity meters into cloud-connected assets with remote load control, and monitor factory energy down to each feeder.
Continuous electrical and thermal monitoring of distribution and power transformers, with smart alerts so field teams act before a failure.
Connect legacy PLCs, sensors and panels to the cloud. We serve ETP/STP/WTP plants, BMS integration, and flood and disaster monitoring.
Product portfolio
Padmashakthi IoT Technologies supplies Krionix, UEIoT and Hexitronics products under one roof. You get one partner for sourcing, integration, commissioning and support.

Makes any existing electricity meter smart and cloud-connected in minutes. The install is tool-less and non-invasive, and it plugs into any standard Head-End System.

Mounts over the register of an existing mechanical meter and reads the certified digits with a camera. Every reading is backed by an image. No pulse mismatch, and no need to open or recalibrate the meter.
A full-bore ultrasonic bulk meter on the supply main feeds a Hexitronics 4G telemetry unit over RS485/Modbus. The result is a live water balance: bulk inflow against consumer usage.

Real-time electrical and thermal monitoring of transformers, with predictive alerts, health status and downloadable reports.

Tracks power factor in real time and monitors each capacitor step for health, with instant fault alerts. Fits LT and HT panels.

Real-time consumption and power-quality monitoring for plants, commercial buildings and energy audits. Connects over RS485 to your existing meters.

Plug-and-play gateways that scan continuously and push sensor data to the cloud. They work with Honeywell, Amphenol, Bosch and Bourns sensors.

Secure remote data logging and high-precision recording of electrical parameters for compliance, analysis and troubleshooting.

A standalone AMR unit that reads meters over RS485, shows status on a local display and reports to AutoStack™ over 4G.

A portable induction motor testing kit, plus continuous vibration, temperature and current monitoring with predictive maintenance alerts.
For new connections and smart-city rollouts: a high-accuracy meter with built-in IoT, leak detection and city-scale onboarding.
We take custom hardware, firmware and cloud work from concept to deployment. This includes BMS integration, ETP/STP/WTP plants and Edge-PLC projects.
The transformer and APFC images are illustrative renders. All other photos show our devices. Contact us for datasheets, pricing and pilot proposals.
The platform
AutoStack™ is our in-house IoT cloud platform. When a device is activated, AutoStack provisions its storage, dashboards and access automatically. A rollout that would take weeks of backend work takes hours.
Unique device ID, barcode capture, bulk CSV import, geotagging and consumer mapping.
Separate portals for consumers, operators, administrators and government authorities.
A canonical data contract with HES/MDMS adapters, APIs and an audit trail.
Deploy on our cloud or on your own servers, with secure M2M SIM connectivity.
WhatsApp, email and Telegram alerts, plus scheduled PDF/CSV reports.
AI-assisted analytics for anomaly detection and NRW insights.
On every screen
Operators see live voltage, current and load trends from any browser. Field teams get the same data on their phones.
From our lab & the field
Our team designs, assembles and tests every device before it goes to site.






Engineering
We design every board in-house, from the power stage to the 4G modem. Tap a block to see what it does.
How we deploy
A clear, staged path. Each stage has its own sign-off, so you see results before you scale.
We audit your meters, panels and connectivity, and check compatibility.
We fit a small batch and agree the KPIs: read rate, uptime and accuracy.
Zero-touch provisioning, consumer mapping and geotagging.
We roll out in phased batches, with bulk CSV onboarding and fleet health dashboards.
OTA updates, field service and SLA-backed support.
Why Krionix
Serviceable meters stay in the field. We upgrade the communication layer, not the whole asset, so you avoid the cost of replacing meters.
We design the hardware, firmware, connectivity and cloud in-house, so we can customise quickly and support you directly.
The architecture scales to smart-city and DISCOM deployments and is aligned with Make in India and Atmanirbhar Bharat.
Choose CAPEX purchase with a perpetual licence, OPEX/SaaS subscription, or AMC and support. Pick what fits your budget cycle.
In partnership
Three brands, one engineering ecosystem. Padmashakthi IoT Technologies works with Hexitronics and UEIoT, and all three product lines are available through one point of contact.
