Backup/restore object values with storage.set/get? - morkovka - 21.09.2021
Hi,
I have a script which runs some logic for a scene (e.g. dim the lights, set color X for RGB, etc.) - but before running it, I want to be able to provide a list of group addresses to 'backup', and then to 'restore' them after the scene finishes - can anybody help with this?
E.g. if we have:
Code:
backuplist = { '1/1/1', '2/2/2' }
save_values(backuplist)
grp.write('1/1/1', 52)
grp.write('2/2/2', false)
load_values(backup_list)The group addresses will have different value types (boolean, percentage, int, etc.).
I'm not sure how to best implement the save_values() and load_values() functions - any ideas?

If this is inside a single script you don't need to use storage at all.
Code:
backuplist = { '1/1/1', '1/1/2' }
-- save current values
values = {}
for _, addr in ipairs(backuplist) do
values[ addr ] = grp.getvalue(addr)
end
...
-- restore values
for addr, value in pairs(values) do
grp.write(addr, value)

Thanks, this is very helpful.
I am using an event script, sometimes it's called with value 'on' and sometimes 'off' - in this case, I assumed I'll need to store the backuplist in storage, is something like the below the correct approach?
Code:
backuplist = { '1/1/1', '1/1/2' }
-- save current values
values = {}
for _, addr in ipairs(backuplist) do
values[ addr ] = grp.getvalue(addr)
end
storage.set('backuplist', values)
...
-- restore values
values = storage.get('backuplist')
for addr, value in pairs(values) do
grp.write(addr, value)
end
