Daniels had led 17-13 in the women’s bowls final before New Zealander Edwards stepped up her performance.
“It started off well and I managed to get ahead but at this level I know that is never the case for very long,” said Daniels.
“I never thought it was mine because I know the calibre of Jo. She came back at me and I had a few loose ends which probably cost me the gold medal.”
Daniels’ fellow bowlers Wyatt and Salmon had earlier guaranteed themselves at least silver after winning their men’s pairs semi-finals against the Cook Islands.
The Welsh pair play Scottish duo Paul Foster and Alexander Marshall in the early hours of Monday morning for gold.
Boxer Eccles is also guaranteed at least a bronze after defeating Tongan flag bearer Magan Maka in the women’s 69kg quarter-final and the Cardiff University student will fight for a final place on Wednesday against Australian Kaye Scott.
Lynsey Holdaway was defeated by Northern Ireland’s Kristina O’Hara in the 48kg quarter-final, while Billy Edwards lost to Zambian Nkumbu Silungwe.
