Sadly I didn’t think to get a “before” signal reading. I do know, that I could barely get the unit on the network before the antenna mod due to the metal case of the floodlight. The tasmota signal strength bars showed 1 bar. Afterwards its doing fine sitting around -68dbm and full bars. I’ve got one more I want to do and I’ll do a before and after for that and update this thread.
As far as the ground / signal question. I severed and removed a section of the antenna trace leading to the printed antenna, disconnecting it fully, then scraped off the mask on the board where the surface mount connector would need to be grounded. I also then used the overlap of the UFL ground lead to bridge the printed antenna into the ground plane on the board in hopes to prevent any possible interference.
