Data Spikes in PZEM-004T v3.0 Readings

[f1netune]

Hello, I prepared a sensor network which including pzem004t v3.0 (100A) sensors based on LoRa communication.

I am currently using the PZEM-004T module with your library to monitor voltage, current, power, and energy data. While the readings are generally accurate, I occasionally observe significant data spikes or anomalies in the sensor output. Here are some examples:

Received from Node 4 V[V]: 237.90 I[A]: 906166.25 P[W]: 538.60 E[Wh]: ovf RSSI: -114 SNR: -9.75
In contrast, the majority of readings from the same nodes are consistent and within expected ranges:

Received from Node 2 V[V]: 235.40 I[A]: 14.34 P[W]: 505.30 E[Wh]: 103.62 RSSI: -108 SNR: 5.25
Received from Node 3 V[V]: 233.90 I[A]: 14.97 P[W]: 613.10 E[Wh]: 103.04 RSSI: -114 SNR: -1.50
These spikes occur sporadically and seem unrelated to actual load or environmental conditions. Could you please provide insights into why such anomalies might occur?

Here are a few questions I hope you can help clarify:

Are these spikes likely due to communication errors between the ESP32 and the PZEM module?
Could this behavior be caused by electrical noise or improper grounding in the setup ?
Is it something that LoRa can cause?
Are there any known limitations or quirks in the PZEM-004T hardware or the library that could result in such anomalies?
Any guidance or recommendations for mitigating these spikes would be greatly appreciated.

Thank you for your time and support.
