Re: Forum Slow Today 15/02/25

I'm not posting a lot, but I log on to the forum about 5 to 6 times a day to see what's new (also to PM with other members who have language problems). Since this threat was posted about 3 weeks ago, I have not notice ANY "slow" periods. Maybe that's because I live in Western Canada, which...

Re: Unexpected Rain Reset

I have two GW1000B gateways, both with current firmware (v1.7.7). For some reason, both showed February as Rainfall Season in the WSView plus app. Pressing the reset button on the rain totals screen changed it back to January. I have attached my log file with the reset error at line 2666 20250129-06...

The Zambretti Forecast, always good for a surprise

For weeks now the Pacific Northwest sits under a slow moving weather system ("heat dome"). Well, according to Zambretti some relief from this sweltering heat is coming: :D

Unfortunatelly, the national met service begs to differ: :groan:

ApplyData: Error, missing wind data

I run two instances of CMXv4, one using the Ecowitt API, the other uses the Ecowitt HTTP protocol. While the API instance reports no errors, the HTTP version reports: 2024-04-21 12:09:59 - ApplyData: Insufficient data to calculate Apparent/Feels Like temps 2024-04-21 12:09:59 - ApplyData: Insufficie...

b4019: API tag: Error - Object reference not set to an instance of an object.

I've just upgraded from b4018 to b4019 on a Pi3 (32bit bookworm) using the Ecowitt HTTP protocol. On startup I get the error 2024-04-06 04:45:00.718 API tag: Error - Object reference not set to an instance of an object. The program seems to be running fine though. I don't get the same error on a Pi4...

"You are not running the latest version of Cumulus MX"

While I find the new "last error" feature quite useful, I don't think that "You are not running the latest version of Cumulus MX" is an error, but a decision on my part not to upgrade at this time. I would suggest to not flag this as an "error".

Wind data recorded by Ecowitt API vs. HTTP

My Ecowitt weather station uses 4 external sensors/modules that send data to two GW1000 gateways. One gateway is paired with a Raspberry PI4B running Raspbian Bullseye, the other one with a FriendlyARM NanoPi M1 running Ubuntu 20.04.6 LTS. Both have CumulusMX v3.27.0 installed, the Raspi uses the Ec...

Wow, that did the trick. :clap: Attached is the old cumulusmx.db. Hopefully it will give you a hint what happened here.

Re: Top of the hour data missing / not processed

Mark, I've changed the protocol to "Ecowitt API" per your suggestion. I've attached the debug log covering about 4 hours' worth of data and the relevant part of the Oct23log.txt file. I'll keep the debug log running in case you need more data. The error in line 123 of the debug log "G...

Top of the hour data missing / not processed

A week ago I updated my Raspi4 and afterwards rebooted. For the next two hours everything ran as normal, but ever since on the full hour the data in the monthly log file is missing, the extra web files are not processed and the 3rd party data are not uploaded. I'm pretty sure this is NOT a CumulusMX...

Re: Cumulus reports air quality data although sensor not connected

Did you stop and restart CumulusMX after you 'removed' the WH41 ? No, I did not. And I don't really see why it should make a difference. From November to March I also disconnect the rain gauge and the log shows this as "Error, missing rainfall". I would expect a similar message when there...

Cumulus reports air quality data although sensor not connected

Due to the severe weather with close to -40°C last week I brought my WH41 air quality sensor indoors to prevent damage to the batteries. I also disabled the sensor in the GW1000 configuration. I did not deselect Extra Sensor 1 in the Cumulus configuration. With no data coming from the gateway, Cumul...

Re: Low Battery Warning - Cumulus Console

I don't know if this is related, but I've seen low battery warnings for my Ecowitt WH32 Temp/humidity sensor even with brand new lithium AA batteries. As it turned out, the reason was a poorly chosen location for the transmitter, facing AWAY from the receiver. The Ecowitt app showed a connected symb...

Re: Email alerts with gmail account

Sadly, either of the authentication apps only work on mobiles (cell phone or tablet) ... which I don't have. And I'm not going to buy a hardware device (would it even work on a Raspi?), so I guess I will have to live without the Cumulus email alerts.
