This speedlite supports every off-camera mode one might want:

Update on 2018 March 5
Using the latest firmware, 1.29.
I have a Canon 430EX-iii RT on my left and the Yongnuo YN600EX-RT II on my right firing at a cylinder. This allows me to see the shadows cast by the two speedlites and compare their power output. The radio master has configured Gr mode with the Canon as A and the Yongnuo as B.
I ran tests with my Canon 80D in manual mode. I varied the ISO and F-stop to see how well the two speedlites did. The Yongnuo can generate a little more power than the Canon, but at lower output levels (ISO 6400), the Yongnuo's lower limit is higher than the Canon and can result in an over exposed image.
This is easy to deal with by setting a lower ISO (for example, 800), but you have to know this problem exists to workaround it.
This speedlite supports every off-camera mode one might want:
- Optical Master (note the Canon 430EX-iii RT does not)
- Optical Slave
- Radio Master
- Radio Slave
as well as on-camera E-TTL.
As Optical Master, the MODE button selects ETTL, M, and MULTI mode
As Optical Master, group sets ALL, A:B, or A:B, C via the RATIO soft button.
As Optical Slave it is configured for group A, B, or C via the Gr soft button.
As Radio Master, the MODE button selects ETTL, M, MULTI, and Gr mode
In E-TTL mode, it controls ALL, A:B, or A:B, C via the RATIO soft button.
In M or MULTI mode, 3 groups (A, B, C) can have power independently set..
In Gr mode, 5 groups (A,B,C,D,E) can have power independently set.
As Radio Slave it is configured for group A, B, C, D, or E via the Gr soft button.
On a Canon T3i, only 2 off-camera modes are supported: ETTL, Radio Master, Optical Master, as well as on-camera E-TTL.
On a Canon T3i, in Gr mode, the 5 groups are always in Manual mode.
The T3i can not set feet/meters but the Speedlite can.
On a Canon 80D, only 2 off-camera modes are supported: Radio Master, Optical Master, as well as on-camera E-TTL.
On a Canon 80D, in Gr mode, the 5 groups can be set for Manual or ETTL mode.
The 80D can not set feet/meters but the Speedlite can.
