Tempiro is a Swedish company based in Lund that makes a smart fuse for scheduling and controlling electric heaters and other fixed electrical loads such as saunas and EV chargers. The Smart Fuse replaces a fuse holder in the fuse box, and the system is managed from the Tempiro app through a Central Unit.
Tempiro uses Zigbee HA 1.2 between the Smart Fuse and a gateway. The fuse has no Wi-Fi, so it needs either Tempiro's own Central Unit or another Zigbee HA 1.2 gateway. The Central Unit connects to the internet and the Tempiro app, and Tempiro says it keeps regulating temperature if power or internet drops out.
That suits owners of cottages and houses with direct electric heating who want schedules, remote control and spot-price based saving from one app. It is weaker for open smart home setups: Tempiro's own pages mention no Alexa, Google Home or Matter support, and community reports on using the fuse in Home Assistant and Homey are mixed, especially for energy readings.

The main app. It adjusts and monitors heating and electrical appliances remotely, with real-time power readings, schedules including recurring events, hourly spot electricity price charts, settings that lower temperature or switch loads off in expensive hours, car charger control and alarm functions for sensors and door contacts. Published by Tempiro AB. Tempiro's FAQ says it is also available on Google Play, but we could not verify that listing.
The Smart Fuse uses the Zigbee HA 1.2 radio protocol, which Tempiro describes as compatible with other Zigbee HA products. The Central Unit controls devices over the same radio. Tempiro gives about 20 metres indoors as the normal range, less through concrete and metal.
The Smart Fuse has no Wi-Fi and needs a Central Unit or another Zigbee HA 1.2 gateway. The Central Unit page says it connects to the internet but does not say whether by Ethernet, Wi-Fi or 4G. An optional 4G modem and a low-cost 4G subscription are mentioned for homes without internet.
No SmartThings integration found. Tempiro says its Zigbee fuses should show up as a Smart Plug in another smart home system, but it names no specific platform.
No built-in integration found. A Home Assistant forum thread from late 2023 tries the Smart Fuse with ZHA and a ConBee 2 stick. One user got the switch working but not the energy meter, while another could not get on and off control working. No fix is confirmed there. Tempiro does not maintain a Home Assistant integration that we found.
In the same thread one user paired the fuse through MQTT, where it showed as unsupported, and their attempt to add a custom definition failed. We did not find a Zigbee2MQTT device page for it.
Tempiro AB publishes a Homey app (version 1.1.2, last updated about three years before our check). It supports only the Smart Fuse and lists Homey Bridge as required. The listing shows Homey Pro, Homey Cloud, Homey Pro mini and Self-Hosted Server, but also a not-compatible notice for the Homey selected, so check your own unit. A Homey community thread says the app has not been updated for a long time and reports that energy readings did not update.
No Tempiro service found, but IFTTT's own pages were not checked.

Developer or local API
Unconfirmed
The Central Unit page and FAQ do not mention an API. Tempiro's 2017 Ideon profile says the company is interested in software developers for its cloud solution, but we found no public API documentation.
