Get node doesn't report all states

[lukyjay]

Hi

I have deployed a 'get' node on a light to and am using a function node to read and convert the state "OFF" into "on" and vice versa.

When I deploy the flow with the light off, I have found that the 'get' node doesn't return any state. It's not until I switch the light on manually that it then starts to report a state.

Thank you for any assistance you can provide

Hey mate, probably I have the same kind of issue but with slightly different behavior. My flow is pretty simple: And configuration for get nodes target for full payload However I receiving null and node shows ok

However In node returning full correct payload

What I expecting: get node should to return last known state for node

[station7]

Same with me. The payload of the get node is "null" after a deploy of node-red. After a restart of zigbee2mqtt the get node works (until the next deploy).

[Tyraenor]

Same here. I was happy about this project but with this error it is almost useless again. Please fix this...

[andreypopov]

I can't reproduce it

1. Enable Retain option for all devices
2. Deploy only modified nodes
3. show me info from bridge node
4. provide me full z2m config

[andreypopov]

When you do full deploy, mqtt connection is being destroyed, MQTT re-subscribes, but without retain you don't get the latest values.

[lukyjay]

I no longer use the nodered integration so feel free to close the issue if you don't think it's a bug 🙂 I left it open in case the others can confirm the retain flag fixes

Hi, this is definitely a bug. I thought I was going insane, till I stumbled across this. So what's even stranger: I have two installations, one at my home (which I use for the last 2 years) and recently a second installation at my brothers home. For some reason in his Node-RED installation I get this exact problem. Once I restart zigbee2mqtt add-on, then the state nodes reports all payload variables. As soon as I hit deploy in Node-RED, everything come backs at null.

This happens ONLY with group devices of z2m. Individual devices work fine. Also I have retain enabled with the devices on the installation that has this bug. But as I said, individual devices report all values, but groups always return null after NR deploy, till next Z2M add-don restart (and then NR deploy wrecks it again).

In my installation, everything works 100% ok, no matter how many times I deploy. Some something is definitely not right. What can I provide to help fixt this matter?

Both installations are running most recent versions: Node-RED 14.0.1, Zigbee2mqtt 1.29.2-1 and node-red-contrib-zigbee2mqtt 2.6.4.`

See in image below, everything comes as null when getting state of a group. Only thing it can report is that is has 2 members.

Is there any update to this? I have 24 Aqara window sensors with retain: true set and on 2 of those 24 when I change the friendly_name the payload is null in NodeRed. If I don't change the friendly_name then the payload is as it should be.

[andreypopov]

no update, I have no idea Did you try yo restart node-red and zigbee2mqtt?

[underqualifieditguy]

no update, I have no idea Did you try yo restart node-red and zigbee2mqtt?

Yep, no dice :(

My only thought is maybe there is some stale entries in Mosquitto? But it doesn't make sense because I get the payload when I leave the friendly_name unchanged.

before name change:

after name change:

Is there some other custom parameter that I can set which could contain a name for the sensor so that my automations report the right name?
