Sonoff WiFi Smart Stackable Power Meter Tasmota

Article description:

WiFi & Ethernet Smart stackable electricity meter SPM-Main / SPM-4Relay

Already flashed with the latest Tasmota firmware.

This stackable electricity meter enables intelligent management with overshoot protection, monitoring of metadata and electricity statistics.

Via the Ethernet Port, you also have the option of controlling and evaluating the TASMATAVARITE of the SPM without WiFi.

Power consumption measurement: Would you like to know the development of the electricity consumption of the individual stalls? Would you like to realize uniform management for the entire shopping center? With the Ewelink app on your mobile phone, you can monitor electricity consumption without leaving the house. With the Ewelink app you can call up the electricity consumption immediately.

Protection of overshn: If the transfer protection is activated, you no longer need to worry that electrical devices burn, which prevents potential security risks. You can also activate the delay in overload to avoid failure.

128 isolated channels & each up to 20a: 32SPM-4Relais can be connected to a SPM-Main. Each SPM-4Relais has 4 isolated channels. Each channel supports a maximum stream of 20a, no fear of high power load.

Call up energy consumption data for over 180 days: Local memory available on SD card. You can insert the SD card in SPM-Main to download and check over 180 days of your energy consumption from HTTP API at any time of the day. You don't have to worry about missing important information.

Easy installation: You can install the SPM-Main and SPM-4Relais step by step based on the operating instructions. With the guide rail you can easily be installed in the right place so that the room looks simple and tidy.

Note: The SPM-Main-main unit and the 4-relay of the stackable performance meter must be used together. The main unit must be connected to at least one 4 relay to work.

Special features of the Tasmota firmware

Implemented in Tasmota:

Up to 7 SPM-4Relay units that support up to 28 relays.

GUI optimized rotating energy display for 4 relays at the same time.

The button on the SPM-Main introduces a new scan of the SPM 4Relay units.

Blue LED shows the Tasmota WiFi status.

Yellow LED lights up if no ARM connection can be made.

Yellow LED flashes for 2 seconds when an ARM ESP CRC error is found.

Ethernet support

Webui display
