REM Not Providing Data: Troubleshooting and Resolution

Introduction

The Remote Equipment Manager (REM) is a crucial component in managing and monitoring various devices connected to a pool controller. However, when REM fails to provide data, it can be frustrating and disrupt the normal functioning of the system. In this article, we will delve into the possible causes of REM not providing data and provide a step-by-step guide to troubleshoot and resolve the issue.

Symptoms and Error Messages

When REM fails to provide data, you may encounter the following symptoms and error messages:

i2c bus not found: When trying to interact with i2c devices, you may receive an error message stating that the bus does not exist.
TypeError: Cannot read properties of undefined (reading 'split'): This error message is often seen in the REM error log and indicates that the system is unable to read properties of an undefined variable.
npm notice: This message may appear when updating npm, but it is not directly related to the REM issue.

Possible Causes

The possible causes of REM not providing data are:

Power cycle: A power cycle on the equipment may have caused the REM to lose its connection to the i2c bus.
REM version: Outdated or incompatible versions of REM may cause issues with data retrieval.
i2c bus configuration: Incorrect or missing i2c bus configuration may prevent REM from interacting with devices.

Troubleshooting Steps

To troubleshoot and resolve the issue, follow these steps:

Step 1: Check REM Version

Update REM: Ensure that you are running the latest version of REM. In your case, you have tried updating from v8.0 to v8.1, but it's recommended to check for any newer versions.
Verify REM version: Confirm that you are running the correct version of REM by checking the REM logs or configuration files.

Step 2: Check i2c Bus Configuration

Verify i2c bus existence: Check if the i2c bus exists in the REM configuration files or logs.
Check i2c bus configuration: Verify that the i2c bus is correctly configured, including the bus address, device address, and any other relevant settings.

Step 3: Check Device Connections

Verify device connections: Ensure that all devices connected to the i2c bus are properly connected and configured.
Check device addresses: Verify that the device addresses are correctly set in the REM configuration files or logs.

Step 4: Check REM Logs

Review REM logs: Check the REM logs for any error messages or warnings that may indicate the cause of the issue.
Check for undefined variables: Look for any instances of undefined variables in the REM logs, which may indicate a configuration issue.

Step 5: Reset REM Configuration

Reset REM configuration: If none of the above steps resolve the issue, try resetting the REM configuration to its default settings.
Reconfigure REM: Reconfigure REM to its original settings, including the i2c bus configuration and device addresses.

Conclusion

REM not providing data can be a frustrating issue, but by following the troubleshooting steps outlined in this article, you should be able to identify and resolve the cause of the problem. Remember to check the REM version, i2c bus configuration, device connections, and REM logs to ensure that everything is properly configured.
