The GL-S20 Thread Border Router and the two original Timmerflotte temperature and humidity sensors have been working fine. Once they came back into stock at the local IKEA I bought two further Timmerflotte sensors. One of those didn’t want to Commission (needs further investigation) but the other one did Commission successfully, at the first attempt, and took the expected firmware update.

While that third sensor has mostly been OK, it’s periodically dropping off the Thread network. The first time that happened I intervened with a power-cycle, which brought it straight back online, but on a couple of other occasions it came back all by itself.

The main difference from the other two sensors is the distance from the Thread Border Router – roughly 15m, with one 100mm concrete-block wall in the way. Might that be the issue?

Thread networks are expected to operate in a ‘mesh’ topology, with mains-powered Thread devices acting as relays for the radio signals, between the central Thread Border Router and the (battery powered) End devices, so maybe one of those would help?

As a first step I’m going to try moving the problematic sensor a bit closer to the TBR. If that doesn’t work I’ll move the TBR much closer to the sensor.
