Edit Block Meter Bug

[s-egge]

Some of the buildings appear to have duplicate/extra meters on the dropdown menu of the Edit Block

Buxton Hall

Buxton Electric is the default and only has Net Energy Usage (kWh) as a measurement

There are two "Buxton Electricity", both have all measurements in the drop down but only the third one works. The second one shows "No Data Available" for the measurements that I checked

McNary Hall

McNary has two Meters, both have all of the Measurements and all of them seem to work and are identical data

Dixon Rec Center

"Dixon Rec Center" is the default and has all of the measurements. "Dixon Recreation Center" only has one and throws an error when attempting to use it.

When switching the meter to Dixon Steam, the Measurement auto-fills as accumulated_real which will cause issues if it's not changed manually to one of the drop-down options.

This is not exhaustive, though most of the other residence halls that I checked appear to behave normally.

Summary of Findings

Buxton

• Top 2 meter groups on Edit Menu include meter ID 38 which reports no data (refer to Browser Debug section below), which is probably why the Measurements (points) menu is bugged for those 2

McNary

• From what I can tell these are 2 different meter groups that both have the same meter (meter ID 6) in it. Valid data, just redundant

Dixon

• "Dixon Recreation Center" Meter Group calls meter ID's 5 and 7. Since one of these is Electricity and the other Steam, that's why it is bugged
• For "Dixon Steam", you're correct that there seems to be a frontend bug with meters of incompatible energy types showing up in the Edit Menu when they shouldn't, could be something to fix in the future
  • Also seems to be the case for other buildings with multiple energy types, e.g. Student Experience Center, Nash

Fixes

Buxton / McNary

(and any other similar issue buildings)

• After double checking that the meter group is either invalid or redundant, you can just delete the meter groups in question from the database, or if you're not sure, just change the building_id_2 column of the meter group to NULL or something
  • delete * from meter_groups where id = <meter id value>

Dixon

• Probably a more long-term frontend PR needed, starting with edit_card.vue

Browser Debug Network Tab

• Other than changing the meter group in the meter menu dropdown, you can also change the "from" or "to" dates to force the API requests to send again (helpful for the default meter group)
• Remember, these are technically meter groups, so some options on the Edit form may result in multiple API requests being sent
• In the case of Dixon, "Dixon Recreation Center" meter group sends requests to meter ID's 5 and 7. As shown in Network debug tab, meter 7 is defunct (more on this below). See screenshot
  

AllBuildings API Call

• Go to https://api.sustainability.oregonstate.edu/v2/energy/allbuildings in browser
• Copy paste output (after the API call finishes) into https://jsonformatter.org/ or something similar, Ctrl F for meter group / building names
• Data is sorted by Building, then meter groups per building, then meters per meter group

MySQL Workbench

• See https://osu-sustainability-office.github.io/docs/database#relationships-between-tables
• Generally clunkier than the AllBuildings API call, but:
  • select * from meter_groups (reference building_id_2 column for buildings table foreign key)
  • select * from meter_group_relation (meter to meter_group relationships)
  • select * from data where meter_id = 38 order by time DESC; (example meter ID, useful to see when last valid data is from)

SQL DB Changes

I used MySQL to select * from meter_groups, then sorted by building_id_2 in order to look for duplicate building IDs with duplicate names (like Buxton Hall and Buxton Hall Electric). After confirming via the Energy Dashboard which were actually duplicates or which had no data, I set the building_id_2 to null for now to make sure there aren't any adverse effects before deleting them.

There were changes in 4 buildings:

• Buxton

  • meter_group IDs 63 and 152 building_id_2 set to null
  • meter_group ID 63 set default to 0 (page was no longer loading after setting the building_id_2 to null
  • meter_group ID 153 set default to 1 (63 was originally the default and had valid data, but only one meter, whereas 153 has all of the meters)

• McNary Hall

  • meter_group ID 13 building_id_2 set to null

• McNary Dining Hall

  • meter_group ID 12 building_id_2 set to null

• Dixon Recreation Center

  • meter_group ID 14 building_id_2 set to null
