More indications that affect reliability
Wiring up a LZW31-SN in a weak-signal environment, the LED shows GREEN indicating that there is sufficient signal, but that seem sot be overly optimistic; the network (Zwave2MQTT-2.0.6 + Aeotec USB) shows some high error-rate, effectively marking the switch as dead.
I would prefer two indications:
-
SIGNAL: Signal is not just raw power, but fidelity on that link (spot the network guy here)
- Is it possible to give the GREEN signal-OK indication to use a correlating portion of the LED bar, like how dim-level is probably shown, to show borderline signal cases? Currently it implies “you have zero signal” or “you have 100% awesome signal”, but really, I have so-so signal, and would benefit from a repeating network node somewhere between the closest hop and the LZW31-SN. Or maybe would. Who knows?
- BER being a part of signal, is it possible to shade the part of the LED slider that would be unlit for “so-so signal” with RED indicating the number of bogus/error/bad/corrupt packets received?
-
Load current: you need ~25W load to get the proper current; how about some indication of what the current might be, or some way to see that Yes, the LZW31 has power to run, but the current is out of bounds due to load being too low?
My situation is not unusual, I don’t think: edge of the network, good signal, but errors on it, and the Load is close to 25W, and LZW31 powers up, but acts strangely, doesn’t show a non-neutral config (item number 47 or so in the sequential list 
) and may have other problems, but I can’t see inside the opaque box.
In any case, signal about the possible causes of failure is helpful so that we’re not debugging by smell, optimism, and lucky dice
