Horstmann/Secure SRT-321 Thermostat - Zwave

Have installed this, and it appears as a node - see below - but it also seems to force 2 additional nodes to appear - node 12 and 14 in the below - these never initialise, and I can’t delete them - tried setting “is_dead” to false, deleting but they just re-appear. Any guidance on this most welcome.

Sorry that should say - tried setting “is_failed” to true and deleting.

Solved problem: forced a delete of the nodes using this method.
