Thank you for hass-node-red, it has some really cool functionality. I'm trying to use the number function in a flow which changes the volume of a multizone amplifier. I have it configured as a slider 0 - 100 in steps of 1. If the mode is configured as "Set Value", the value is successfully passed through from input to output. Is there away for it to do both, I have been using the Node Red Web Dashboard slider successfully for quite some time. Thank you, |

Use two number nodes, both with the same entity config selected, with different modes selected. |

That worked! - Thank you. Would you consider in time to put that function into one node? |

In my experience, having a single node do more than one action lends to confusion with the general user. |

Hello zachowj, I like to use this node for setting a time for activating a pump for a specific time. is there a possibility to set the time by slider and sent that value to the output by triggering the input with a "true" value? KR |

To have slider show up on Home Assistant side, you will want to set the mode in the entity config to slider. For the trigger/output combo, several nodes would be needed. Option 1: would be to use a current state node to get the current value of the number entity

That I could figure that out myself.... thanks a lot !!! |

I added a get mode to version 0.54.0. You can now use the number/select/text nodes to get the current value.

So, I'm doing something a bit different, and probably all kinds of wrong.... But here we go.... I'm trying to auto-create var NewEntity = {};
NewEntity.type = "create_entity";
NewEntity.payload = {
data: {
type: "nodered/discovery",
server_id: "zonetouch3_zone_" + i,
node_id: "zonetouch3_zone_" + i,
component: "number",
attributes: {
name: "zonetouch3_zone_" + i,
min: 0,
max: 100,
step: 5,
unit_of_measurement: "%",
mode: "slider",
icon: "mdi:hvac",
}
}
};
node.send(NewEntity);The entities appear ok in HA: I'm then trying to set a value for these using a call-service node with number / set value options and the following: // Create a new message to pass to the set-value service.
var NewMsg = { };
NewMsg.entity_id = zone_entity;
NewMsg.payload = percent;
NewMsg.type = "set_percentage";
node.send(NewMsg);The call service is configured as: There's no error when the call to call-service happens, nothing in the debug, etc to indicate a failure, but in the HA entity log, I see: It seems like for whatever reason, the sensor becomes unavailable, and the state always seems to be 'Unknown' or 'Unavailable'. For some context, this is the overview of the flow: Get Status runs every 30 seconds and actively queries the ZT3 device. The |

Oh man, after a couple of hours hacking in the ZoneTouch 3 protocol stuff into that, it seems to work very well! I'm also trying to add an INJECT node to delete the created entities (mostly for testing etc)... Strangely though, the entities autocreated are named like However, something is weird with either
I'll make it easy on both of us and post the whole flow instead....

the const entity_id = msg.payload.entity_id;
var entity = entity_id.split(".")[1];
entity.replace("nodered_", "");You replace const entity = msg.payload.entity_id.split(".")[1].replace("nodered_","");or const entity_id = msg.payload.entity_id;
let entity = entity_id.split(".")[1];
entity = entity.replace("nodered_", ""); |

facepalm Of course. I wanted to try a cleanup to remove everything so I can test it again with creation on-the-fly and tweak if needed. Javascript is not my strong point - so I'm not used to doing overload operators to do things! I'm the old guy that still swears by perl - and I find that my most common screwup is using the wrong language syntax that just happens to be valid in a different language, but doesn't work as expected 😆 Thanks for all your help on this.... I know I'm only discovering the edges of what you can probably do with HA and NodeRed - and as I've been discovering, the community is great at helping out! I greatly appreciate it. |

Hopefully, only a few more questions as I discover things :) I'm still struggling with the removal... The packet being sent is: msg.payload = {
type: "nodered/discovery",
server_id: entity,
node_id: entity,
component: "number",
remove: true
};In the HA logs, I get: Part of the reason I'm trying to get the delete working is that when we create the entities, I'm sending the following attributes with it: However, in HA, and if I look in the global context, I'm seeing: {
"entity_id": "number.zonetouch3_zone_0",
"state": "51",
"attributes": {

"max": 100,
"step": 1,
"mode": "auto",
"icon": "mdi:numeric",
"friendly_name": "Living Area"
},

"context": {
"id": "01HWEJF46HVXT35YZ9Z2M71SBD",
"parent_id": null,
"user_id": null
}
}I set the friendly_name, so that part is fine - however, either it wasn't created with the right attributes in the first place, and for whatever reason, we can't update them, or the attributes aren't applying. If I send the attributes as part of the Just to rule things in / out, I've been focussing on the delete / remove right now - so I can test with freshly created entities... |

You would only get an unknown command if you sent the message before the NR component was loaded in HA. The properties to set certain attributes can be found here |

I'm looking to have a bidirectional binding between a number entity in HA and a number in a Socket.io server. For the switch entity this is quite simple, as it has an input and output: For the number however, I use two separate entities as you mentioned. Reading the Socket.io value and setting the number entity works. Listening to the state of the entity and writing to Socket.io works too. But when I connect them both, the number gets into a loop, flipping between two values. I find it hard to wrap my head around the concurrency issue I'm running into, any hints on how to implement a two-way (push) binding correctly on a number entity?
