I have object like this and I want change its value to True. Can you help me?

Those all look like Home Assistant nodes?

In Node-red you can use a **change node** like this

No, those are Bitpool Edge Bacnet nodes.

I already have answer to my question.

```auto
To write a value using the Write node, you need to:

1. **Configure the Write node** — open it and add the target point(s) to the write list from the device tree. Set:
  * **Priority** — the BACnet write priority (e.g., `8` for Manual Operator). Use `null` for default.
  * **Application Tag** — for Binary points (BI/BO/BV), use **`9` (Enumerated)**.
2. **Configure the Inject node** — use a standard Node-RED inject node (not the Bitpool Inject) wired into the Write node. Set `msg.payload` to the value you want to write:
  * To set **Active (true)**: `msg.payload = 1`
  * To set **Inactive (false)**: `msg.payload = 0`
  * To **release/relinquish** (clear priority): `msg.payload = null`

So your flow should look like: **Inject → Write → Gateway**

In the Inject node, set payload type to **Number** with value `1` to write Active (true).

BACnet binary points use `1`/`0` (enumerated), not `true`/`false` booleans. The Application Tag on the Write node must match — `9` (Enumerated) for binary objects, `4` (Real) for analog objects, `7` (Character String) for string objects.

```
