What does this Tasmota Rule generator do? This small tool automatically generates the Tasmota Rule1 code, which allows you to send the meter data (power, voltage, current, total energy and the switch state) to the ADA P1 Meter. With this, your socket appears…

This guide is for those who already have a working SlimmeLezer (an ESPHome-based P1/DSMR reader) and want to use the ADA P1 Bridge so that it works not from its own P1 port, but from the raw telegram published over the network by the SlimmeLezer. The goal is…

Many people today already use some type of P1 meter (an existing DSMR/P1 reader) that can output the electricity meter data to the local network. Here comes the classic scenario: the hardware is there, the data is coming in, but you want to use it smarter – i…

Practical example of ADA P1 Meter and ADA485 In the world after net metering, it is increasingly important that the solar power system uses as much power directly in the home as possible and draws as little as possible from the grid – especially in the evenin…

In the post-net metering era, the goal is no longer to feed back as much electricity as possible to the grid, but rather to use as much as possible on-site when the solar panels generate. In gross accounting, imported and exported energy are calculated separa…

The ADA485 is an easy-to-install RS485→IP (Wi-Fi/LAN) bridge and edge gateway. It reads and writes Modbus RTU, publishes to MQTT/HTTP/REST, logs to CSV/JSON, and integrates immediately with Home Assistant/smartmeter.hu/hmke.app systems. Ideal for inverters (D…

The ADA-PN100 is an ESP32-based device that generates S0 (countable) pulses from OBIS data read from the P1 port of smart meters. Its purpose is to provide compatible pulse signals from modern smart meter energy values to PLCs, measurement systems, data colle…

Want the good old S0/pulse output back from your smart meter? The ADA PN100 does exactly that: it reads energy data from the meter’s P1 (DSMR) port and generates programmable pulses to feed your PLC/SCADA counter input – just like connecting a classic kWh met…

In October, a new feature will appear in HMKE.APP! The ADA P1 Meter not only reads now but also controls. You configure the rules on the hmke.app interface, and the device executes them locally from its own memory – even if there's no internet at home. In thi…
