energieleser makes small Wi-Fi readers that clip onto the optical interface of digital electricity meters and also read gas, water and heat meters. Homey lists nineti GmbH as the developer behind the brand. Readings are viewed in the stromleser app and can be pulled into smart home systems through a local API or ready-made integrations.
The electricity reader, stromleser.one, attaches to the D0 infrared port of a digital meter, joins Wi-Fi after a Bluetooth-assisted setup in the app, and sends data to the energieleser cloud for the app. The device also serves a local HTTP API with no authentication, which Home Assistant, Homey and evcc use over the local network. A second variant, stromleser.tasmota, runs open-source Tasmota firmware and works through MQTT.
That suits people who want live household consumption in Home Assistant, Homey or evcc for solar surplus charging, and who can accept a plain local network interface. It is weaker for voice control, because we found no Alexa, Google Home, Apple Home or Matter support, and analogue Ferraris meters are not compatible.

The app for the readers. It shows live consumption, current power, meter reading and possible feed-in, and with stromleser.one also history and analysis. Sign-in works with a Google or Apple account or email and password. The vendor says it is available on the App Store and Google Play, but its pages we read carry no store links, so none is given here. Docs also refer to it as the energieleser app.

What it means
Sources
Connection
Wi-Fi
Yes
The readers join the home Wi-Fi. For stromleser.one the app first connects over Bluetooth, then asks for the Wi-Fi network and password. The documentation does not state the Wi-Fi band. The gas and water readers also use Wi-Fi, and the water reader needs a power outlet.
Used only for first setup of stromleser.one from the phone. The stromleser.one documentation page does not mention Bluetooth, so the function is described on one vendor page only.
stromleser.one attaches to the D0 infrared port of a digital electricity meter. Digital meters with an optical D0 port, including modern measuring devices and intelligent metering systems, are supported, and analogue Ferraris meters are not. Some meter models need a PIN to expose certain fields.
A built-in energieleser integration arrived in Home Assistant 2026.7. It covers stromleser.one, gasleser, gasleser.pulse, wasserleser and wärmeleser, discovers devices through zeroconf and polls the local API every 10 seconds. The listed maintainers are two individuals, and we could not confirm their link to the vendor. energieleser's own docs also describe the integration and say it does not support stromleser.tasmota, which still uses an MQTT-based setup. Home Assistant warns that several integrations polling one device can trigger rate limits.
nineti GmbH publishes the energieleser app, listed as an official Homey developer. It supports stromleser.one, gasleser, wasserleser and wärmeleser, and says data stays on the local network. The listing shows Homey Cloud, Homey Pro, Homey Pro mini and Self-Hosted Server, but also says Homey Bridge is required, and the description refers to Homey Pro, so we could not resolve which applies. It needs Homey 12.4.0 or later.
evcc lists a stromleser.one IR Reader meter template for grid or PV use, reached over the local network by host name or IP. energieleser's own docs describe the same setup as a grid meter for solar charging, without the cloud. This works for stromleser.one only.
energieleser's documentation has a step-by-step page for connecting its readers to Loxone. We saw only the title in the docs index and did not open it.
No dedicated binding or docs page found. The vendor's FAQ says the Tasmota firmware on the Tasmota variant can be integrated into openHAB, ioBroker and Home Assistant, which concerns that firmware rather than a vendor integration.
No Node-RED node or docs page found. The local HTTP API or Tasmota MQTT output could be read from it, but we did not confirm a working flow.

energieleser local API
Official
Plain HTTP on the device's local address, with /v1/data returning JSON whose layout depends on the device. No authentication is required, and the API is not reachable from the internet. The docs ask for at least 10 seconds between requests and no parallel access from other tools, and say availability depends on firmware version. stromleser.one and gasleser have their own pages.
stromleser.tasmota runs open-source Tasmota firmware, shows data in the Tasmota interface and uses an MQTT-based Home Assistant setup. The stromleser.one docs do not mention MQTT, and the docs index mentions MQTT setup in a category description without a dedicated page.
A B2B page describes an energieleser portal for managing objects and meters across locations, an API for utility billing and consumption information, data export, and data transfer through an integrated SIM card to a platform or chosen endpoint. It is aimed at business customers, and no pricing or terms were visible.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
