I have two Node-RED setups with Tellstick Duo. They mostly read the same sensors, but only one of them reads the THGR221, and I can't understand why. The range isn't the problem, because the one that doesn't read it is a lot closer to the Oregon sensor than the one that does read it, also it reads other sensors (like Viking and Oregon THN132N) that are a lot further away tha the THGR221, which is actally in the next room. So is it possible that I have two different firmwares on those Duos? Is there firmware at all on those?
