NFE Tech Huddle - April 3rd 2026

Quick summary 

 During this meeting, Aaron, Hillary discussed, the current meter-logging system, data buffering and aggregation approach, deployment pipeline, backup and metadata storage, and commissioning/precommissioning of meters. 

 Action items for Aaron 

 

 Wrap up gateway deployment repo and onboard Hillary so he can use it going forward 

 NFE Web app integration with real (CSV) data via nextcloud once Hillary has populated sample meter data; coordinate timing for verification. 

 

 Action items for Hillary 

 

 Implement and enable the 15-minute buffering and averaging approach (already in place) and ensure exported log entries represent averages for each 15-minute window; document the buffering logic. 

 Adjust the backup/upload timer to start with hourly uploads and monitor cost/performance; report recommended cadence after initial test period. 

 Deploy the meter services to the other production Pi and validate that the metadata folder is populated with meter folders (start tonight where possible). 

 Add a commissioning/precommissioning script that converts meters from the Chinese protocol to Modbus, assigns temporary address 1 for precommissioning, then writes the production address and serial number; document the commissioning procedure and constraints (e.g., stopping services may lock serial port). Onboard Dansturn to execute on this 

 Share the correct metadata/metadata folder link and confirm access is granted to Aaron; reorganize folder structure as discussed (metadata -> customer -> meter folders). 

 Test image building and deployment flow (VM build -> push to main -> CI build image -> manual deploy) and document the exact deployment commands. 

 Test upgrading the client version in a staging environment and report any compatibility/security concerns before upgrading production. 

 

 Notes: Hillary already demonstrated the buffering (10s sampling, 15-min average) and the backup/upload service; team agreed to start with hourly uploads and scale as needed. Commissioning constraints and Modbus address conflicts were discussed; precommissioning workflow will be created to avoid on-site conflicts.
