I have an EmonPi which receives data from two EmonTx units, one for the house and one for the garage. The EmonTx in the house is a few metres from the EmonPi, and the connection is very good. On a OpenCMS graph, data quality is typically 99%.
The EmonTx in the garage sometimes works normally, but frequently fails to report data for long periods - sometimes hours at a time. Switching it off and on again doesn’t solve the problem. As this EmonTx is further from the EmonPi, I’ve been putting up with the data loss because I had assumed that the data loss was caused by either the distance or by interference from something outside the house.
However, I’ve just bought an additional EmonTh which I’ve put in the garage, and the EmonTh doesn’t experience much data loss. It’s possible that the EmonTx in the garage is faulty. Is there anything I can test to help track down the intermittent problem?
EmonPi (purchased in November 2016).
House EmonTx (v3, purchased in March 2017). RSSI is -44
Garage EmonTx (v3, purchased in November 2017). RSSI is currently -69.
Both EmonTx units are powered by the original AC adaptors that they were supplied with, and are running the original firmware.
