Sorry Dave, I’ve only just seen this!
Indeed, I’m still struggling. I bought a couple of different sensors, none of which have worked thus far. Youshiko have smartly hidden any model no. Or address codes on the sensor, so it’s a bit of a guessing game when it comes to finding a sensor that reads the same IP address that the board is coded to.
Someone else online suggested it might be IP: 12C / 40. So I’ve bought a SI7021 sensor which arrives in a few days.
looking at the MCP 9808, this is an 8Pin sensor? My one was 4 pin and it very much looked like an AHT25 sensor. However, this was tiny and I can’t even find a Molex small enough to hook it up. My soldering skills are not very good for micro work either. Ha.
It’d be interesting to see your replacement, but only if it’s no trouble.
failing the third attempt at a fix, I might think about investing in a better unit.. Youshiko customer care is just awful.
many thanks!
