I hear you. Not trying to convince you one way or the other. Just saying what I think is best...just an opinion. I've been here long enough and have seen these threads come and go...MANY times (ad nauseum 
). The end result is the same.
Build mesh to support the lock (what I did initially and worked well on HE).
Buy different lock (zwave or zigbee or other).
Buy/use different hub that does not have this issue.
My locks are on Home Assistant now- guess what..they had problems with missed events and severe battery drain. I started with the process of trying to get them working...then realized I had already spent the time getting them going on HE...and decided it was just better to go with the zigbee version. BEST thing I could have done.
Not saying you should do the same but if this automation thing ever gets to a point of frustration that I can't buy my way out of....then I'm done with the whole endeavor. It's supposed to make life easier, not more stressful.
