Hi,it works great on a good majority of the data - it may be tricky when
the stim channel baseline is not zero.

Functional code example + outputs below:
================================================
evts = []
evts = mne.find_events(sss, stim_channel=stim_channel, output='onset',
                         min_duration=0.001, uint_cast=True,
initial_event=True)
print(evts)

2 events found
Event IDs: [1 2]
[[ 55511      0      1]
 [355513      0      2]]

#______replace event value
newevts = evts

for t in (0, len(evts)-1):
    if evts[t][2]==1:
        newevts[t][2]= 102
    if evts[t][2]==2:
        newevts[t][2]= 202

#______add and save
sss.add_events(newevts, stim_channel, replace=True)
sss.save(main_dir + 'blah_nosss.fif', overwrite=True, verbose=False)

#___TEST________________________
tmp  = mne.io.Raw(main_dir + 'blah_nosss.fif',
allow_maxshield=True,preload=True)
blah = mne.find_events(tmp, stim_channel=stim_channel, output='onset',
                         min_duration=0.001, uint_cast=True,
initial_event=True)
print(blah)
2 events found
Event IDs: [102 202]
[[ 55511      0    102]
 [355513      0    202]]
===================================================


Best,
