Any straightforward IR Zigbee blasters?

FWIW, I’m using a TuYa ZS06 and haven’t noticed any delay.

It’s mains powered, also acts as a Zigbee router, and I use mqtt.publish (never tried text.set_value so I can’t say if it’s faster/slower/same).

I used it to automate a range hood (a k.a. kitchen exhaust fan).
