I would say that Ambient isn't just behind in getting new Fine Offset stuff...but sometimes they opt to not carry something at all. Their claim is that they value their customers and they really test everything before they decide to carry it. Even still some products they just pass on because the feel they don't need to carry everything as they only carry what they think they can sell. Although many of us on this forum may be true enthusiasts that would love an SHT35 based temperature/humidity sensor, the truth is that for what makes up the majority of Ambient's customer base, this fancy premium sensor is likely not on the radar of the majority of their customers. It likely isn't on the radar of most of Ecowitt's customers either but it seems like Ecowitt is carving a name for itself to cater to our type of crowd.
