I don't know if you guys have an ST hub running by chance but I have these remotes paired to my ST hub and use SmartThings palette in Node Red to control devices paired to HE with them. Until recently, I was using HubConnect and there was a 1/2 - 2 second delay. Now I am using the ST node that is local using webhooks and it is MUCH faster. It's not always perfect but definitely MUCH better.
It's an option for those who might have already have these remotes paired to ST and are nervous about going to zigbee2mqtt like I was.
