my old vantage pro2’s additional wireless temp station at ch2 (iss is at ch1) has carked it (crushed in tree fall). it exists no more; it is not transmitting. my vp2 data logger is faithfully reporting a phantom value of about 150 C (not bad for a river!) every few seconds, how do i disable this phantom?

i tried (with weewx not running) ‘wee_device --set-transmitter-type=2,10’ to set ch2 to none, but all i get is an error ‘No <ACK> received from Vantage console’, and it continues reporting the phantom when i start weewx again. how can i stop this phantom?
cheers

Given such a whacko figure, perhaps under the [[Corrections]] section under [StdCalibrate], or more suitably, something under [StdQC].

QC is filtering out the bad values, but weewx server is currently resetting after 4 failed retries on regular basis while the phantom station haunts the vp2. there is no radio signal being transmitted to provide the extraTemp1 values, it is just a figment of data logger’s imagination. the phantom battery-low apparently from the ex-station stopped yesterday, but the data logger is still reporting the extraTemp1 despite my (failed) wee_device instruction just now to desist

i do ‘wee_device —set-transmitter-type=2,10’ and it gives ’no <ack>’ error.
then i do ‘wee_device —info’ and it reports ch2 still enabled
so it is not just a case of resetting memory/power

weewx v4.5.1 using python3.7 on RPi 4B running buster with usb/serial
(vp2 firmware is from 2004. lately weewx has been resetting whenever the (now ex-) extra station reported low battery, so this bogus extraTemp1 value upsetting weewx is kinda understandable → i need to turn all vestiges of the (ex-) extra station off)

An alternative might be to use a different driver - does rtl_433 pick up its transmissions? If so, using the SDR driver could work, and you wouldn't have weewx resetting after failed USB comms.

Can't you set transmitter IDs manually via the console?

data logger is in an envoy

Doesn't leave many options. Can't power down/reset the envoy?

i can power down, pull it apart, put the batteries in backwards. how do i reset it?
(and why would wee_device be failing to reconfigure ch2 but work successfully otherwise?)

I don't have an Envoy but I understand it is a case of removing all power sources, including batteries, waiting for 10-20 seconds for any capacitance to discharge and then power up again. Don't know I would put the batteries in reverse though.

did that - envoy has now forgotten the old wireless station [RESOLVED] - thanks

it has been a lot of years since the envoy was last unpowered!
