Missing humidity sensor and temperature reports being ignored for newer ZXT-800 model

[jbarreiros]

The problem

Greetings. I'm having trouble with a zwave device.

I picked up a Remotec ZXT-800 about a year and a half ago, and it's been a great little device. It reliably controls my mini-split, and consistently reports both temperature and humidity every 15 minutes.

Recently, I purchased another ZXT-800 for my other mini-split. It controls the mini-split just fine, but...

1. the humidity sensor is non-existent,
2. and no matter how many times I try to change the "Temperature & Humidity Reporting Interval" to "15 minutes", the temperature graph only shows data points every 6 hours.

It should be noted that Remotec did release an updated model. My original ZXT-800 is model BW8492 and this new one is model BW8493.

Please let me know if there is additional information I should be providing. I was originally going to open a discussion over at node-zwave-js, but the page suggested starting with Home Assistant.

Thank you.

Diagnostics information

This is the diagnostics file for the original ZXT-800 (the one that completely works):

Anything in the logs that might be useful for us?

Issue 1: Temperature (and humidity) values not being recorded every 15 minutes

The device appears to be sending the temperature every 15 minutes (which is what I want):

2024-12-24T18:58:31.336Z CNTRLR   [Node 038] [~] [Multilevel Sensor] Air temperature: 14.7 => 14.7  [Endpoint 0]
2024-12-24T19:13:31.293Z CNTRLR   [Node 038] [~] [Multilevel Sensor] Air temperature: 14.7 => 14.6  [Endpoint 0]
2024-12-24T19:28:31.208Z CNTRLR   [Node 038] [~] [Multilevel Sensor] Air temperature: 14.6 => 14.5  [Endpoint 0]
2024-12-24T19:43:31.122Z CNTRLR   [Node 038] [~] [Multilevel Sensor] Air temperature: 14.5 => 14.5  [Endpoint 0]

But, when I look at the sensor's graph, it is showing data points only every six hours.

Later on in the logs, I see the following, which does show up in the sensor's graph.

2024-12-24 19:00:52.782 INFO (MainThread) [zwave_js_server.server] 2024-12-25T00:00:52.779Z:

2024-12-25T00:00:52.780Z CNTRLR » [Node 038] querying Air temperature sensor reading...             [Endpoint 1]

It appears those every-15-minute reports are not being recorded, and the temperature is only recorded when Zwave explicitly queries for it.

Issue 2: Missing humidity sensor and values

Unlike temperature, there are no incoming reports for humidity.

The following seems interesting:

You'll need to report this to node-zwave-js.

The temperature unsolicited reports are reported on endpoint 0 but HA only knows about endpoint 1.

Similarly, the humidity values never make it to HA.

[jbarreiros]

Thank you @kpine, will do.

[dirtywater12]

Is there a remedy to this yet? Is the error on the configuration side or the Firmware side?

[kpine]

You should ask at zwave-js/node-zwave-js#7532.
