One of my ST arrival sensors dropped off line, and I noticed it had high RSSI numbers.
I replaced the battery 2 days previous.
I put another ST arr. sensor next to it, with a fresh battery, and it had much better RSSI numbers.
The fresh battery, before install, read 3.334v.
The battery that was in service for two days read 3.039v.
Can battery strength affect the device's RSSI?
Note: They are cheap CR2032 batteries.
yes, as more power will allow the antenna to send a further signal. power = voltage * current, so higher voltage will lead to higher power
Okay, for laughs I put in a new battery in device 1790.
Same numbers.
Either that device is crapping out or 1292 is a Super Device.
I don't think I'm gonna break out another ST Arrival Sensor to continue the experiment.
I'll just decommission 1790.
Some devices don't update battery right away. You can force it by resetting and repairing (Zigbee will just slot right back into place) Also be aware lithium batteries don't always report properly because of the way they deplete...
This is RSSI vs battery strength.
I'm starting with fresh batteries in both.
It started with a device falling off the mesh.
It's in the garage, so not ideal, but it had been solid for a while.
The difference in RSSI between the two sensors, in the same location on a car window, with fresh batteries, is quite dramatic.
Oh I get that, was just mentioning the way lithium is read so it's hard to determine with things are going sideways
It's just that I haven't had a sensor slowly crap out like that, if indeed it is.
Maybe I mishandled it and did something to the antenna when I changed batteries.
