I have 4 HX711 cells in wheatstone configuration. Use it from Home automation to measure bed presence. Worked correctly for a few weeks, but suddenly stopped working (cannot get any useful readings anymore). I suspect one or multiple wires has a broken connection.
I did measure resistance across all the pins, but they seem incorrect. Measure values are in kOhm. Real readings where 1.48, 0.99 etc, but I rounded this in the listing below. I don’t think this should be an issue. Afaik the resistance value between all the pins should be 1 kOhm.
E- | A- | 1.5 E- | A+ | 1.5 A+ | A- | 2 A+ | E+ | 1 A- | E+ | 0 E- | E+ | 0
Could someone tell me by this figures which wire is the problem?

- why not just measure each of the load cells? always try the easiest solution first. – Kartman 27 mins ago
- I cannot measure the individual load cells as they are mounted under my bed legs and all soldered in the wheatbridge configuration. – Bram Gerritsen 8 mins ago
