01 · Ingest
From any meter, any source, any country.
Every portfolio has a mix of meter types, building-management systems, manual processes, supplier portals, and invoiced data. The buildings span decades of vintages, the IT footprint is minimal, and there's rarely an engineer on site. Most platforms force one path. Wia takes all of them.
We flip the economics of data collection. Retrofit hardware sits on live meters, cellular and LoRaWAN backhaul means no IT presence is needed, and site staff, your local FM team or an electrician fit it in under an hour per meter. That changes the question from 'is the data worth collecting?' to 'what should we do with it?'
How rollout works
Three steps. No engineer on the ground.
01
Remote survey
We map your sites and meters from your existing documentation: single-line diagrams, BMS exports, photos. No site visits, no consultants. The output is a hardware bill of materials per site, ready to ship.
02
Local install
Hardware ships to site, pre-configured for that meter. Site staff, your local FM team or an electrician fit it on the live meter, usually in under an hour. Buildings stay on, tenants are unaffected.
03
Data flowing
The device comes online on cellular within seconds of power-up. First readings hit your dashboard within minutes. Within 24 hours we have a baseline for that meter.
Inside Ingest
Everything Ingest does, in one place.
Retrofit IoT
Sit our hardware on existing meters: no rip-and-replace, no truck rolls. Reads pulse, modbus and optical interfaces on equipment from the 80s onwards. Devices ship preconfigured to the site.
Cellular & LoRaWAN
No IT footprint required at site. Devices report to one gateway per site, which comes online out of the box on its own Wia-managed cellular link. LoRaWAN covers dense sub-metering inside warehouses and offices where cellular signal struggles.
BMS integration
BACnet and Modbus: connect to what the building already has. Where the BMS is there, we use it; where it isn’t, we add retrofit IoT alongside. Existing automation logic stays intact.
Manual upload
Drag-and-drop CSV / Excel ingestion with validation, preview and conflict resolution built in. For sites that aren’t metered yet, this gets data flowing on day one. Bulk uploads handled in chunks of any size.
Invoice ingestion
Vendor invoices parsed for tariff, consumption and period split. New supplier formats are added as they appear. Reconciles against metered data so discrepancies surface as alerts.
Cloud + Open API
Pull from sites already instrumented elsewhere via direct cloud integrations, or push data into Wia over REST and webhooks. Your existing stack stays in place. Authentication via API keys or OAuth.
Environmental sensors
Wireless temperature, humidity and CO2 sensors per floor or zone, plus outdoor conditions, on the same gateway as the meters. Comfort and air quality sit next to consumption, so a schedule change is judged on both.
Installed in under an hour. Zero downtime.
Retrofit hardware fits on live meters, so buildings stay on and tenants don't notice. Site staff, your local FM team or an electrician fit it, with no Wia engineer on the ground, anywhere in the world.
Coverage
30+ countries. One operating model.
Wia is deployed across logistics warehouses, real-estate portfolios and OEM platforms in 30+ countries. The retrofit-first model means each country uses the same hardware, the same data shape and the same operational playbook. Your team manages every site the same way, regardless of where it is.
No country-specific integration work. No regional dashboards. One operating model worldwide.

FAQ
Common questions
Does retrofitting interfere with existing meter contracts or warranties?
No. The retrofit hardware sits beside the meter: it reads but never modifies. Existing supplier contracts and meter warranties are unaffected.
What happens if cellular coverage drops at a site?
Devices cache locally for up to 30 days and back-fill when connectivity returns.
How long until first data?
First readings arrive within minutes of install. A statistically robust baseline takes 24-72 hours per meter, depending on operational cycle.
Can we run Wia alongside an existing EMS or ESG platform?
Yes. Wia is the data layer. Your existing ESG software, reporting consultancy or analytics stack consumes the data via API, webhook or scheduled export.
