I see zero or missing values for some reactive energy registers. What is wrong?

Some reactive energy and reactive power per-phase registers use uint16 format instead of float32. Ensure your gateway is reading these registers with the correct data type. The template handles this automatically, but manual register additions may need adjustment.

The gateway cannot communicate with the Exor meter. What should I check?

Verify that the RS-485 wiring polarity (A and B) is correct and that a termination resistor is installed if the cable run is long. Confirm the baud rate is set to 19200 and parity is set to odd on both the meter and the gateway.

Can I use this template for a single-phase Exor meter?

This template is designed for 3-phase Exor meters. Using it with a single-phase model may result in empty or invalid readings on L2 and L3 registers. Use a single-phase specific template if available.

What are the T1 and T2 tariff counters?

T1 and T2 represent two separate energy tariff registers, typically used for peak and off-peak billing periods. The Exor meter increments the appropriate counter based on a tariff switching input or schedule configured on the meter.

Free Modbus template: Exor Energy meter 3-phase

Name: Exor Energy meter 3-phase
Brand: Exor
SKU: 84f65cc6-553a-432e-b506-e83930fd8a75

This template reads 3-phase energy metering data from Exor energy meters via Modbus RTU. It covers per-phase and total values for voltage, current, active/reactive/apparent power, and dual-tariff energy counters. No control registers are included.
