Set Value Vbus

[Juan Guillén]

Good morning, I have a DeltaSol MX 2.08 and I try to set the R13 value. I try with this script but not change the state. Can anyone help me please¿? Thank you

const vbus = require('resol-vbus');

const values = [{

valueId: 'Relais_Regler_R13_Handbetrieb',

valueIdHash: 1085278988,

valueIndex: null,

changedValue: 2,

currentValue: null,

}];

function hex(value, digits) {

return `0x${value.toString(16).padStart(digits, '0').toUpperCase()}`;

}

async function main() {

const conn = new vbus.TcpConnection({

host: '192.168.1.174',

password: 'vbus',

});

await conn.connect();

conn.on('datagram', dgram => {

const bytes = Array.from(dgram.toLiveBuffer()).map(b => hex(b, 2)).join(' ');

console.log(`- \`${bytes}\``);

console.log(` - destination address = \`${hex(dgram.destinationAddress, 4)}\``);

console.log(` - source address = \`${hex(dgram.sourceAddress, 4)}\``);

console.log(` - command = \`${hex(dgram.command, 4)}\``);

console.log(` - 16-bit parameter = \`${hex(dgram.valueId, 4)}\``);

console.log(` - 32-bit parameter = \`${hex(dgram.value, 8)}\``);

});

let dgram = await conn.waitForFreeBus();

if (!dgram) {

throw new Error(`No bus offer received`);

}

const peerAddress = dgram.sourceAddress;

// console.log(`PeerAddress = 0x${hex(peerAddress, 4)}`);

dgram = await conn.getValueById(peerAddress, 0x00000000);

if (!dgram) {

throw new Error(`Unable to get changeset ID`);

}

// console.log(`Changeset ID = ${hex(dgram.value, 8)}`);

const valuesToLookup = values.filter(value => (value.valueIdHash != null) && (value.valueIndex == null));

if (valuesToLookup.length > 0) {

for (const value of valuesToLookup) {

dgram = await conn.getValueIdByIdHash(peerAddress, value.valueIdHash);

if (!dgram) {

throw new Error(`Unable to lookup value ID hash`);

}

value.valueIndex = dgram.valueId;

}

// Resynchronize between lookup and get/set

dgram = await conn.getValueById(peerAddress, 0x00000000);

if (!dgram) {

throw new Error(`Unable to get changeset ID`);

}

}

const valuesToSet = values.filter(value => (value.valueIndex != null) && (value.changedValue != null));

if (valuesToSet.length > 0) {

for (const value of valuesToSet) {

dgram = await conn.setValueById(peerAddress, value.valueIndex, value.changedValue);

if (!dgram) {

throw new Error(`Unable to set value`);

}

value.changedValue = null;

value.currentValue = null;

}

// Resynchronize between get and set

dgram = await conn.getValueById(peerAddress, 0x00000000);

if (!dgram) {

throw new Error(`Unable to get changeset ID`);

}

}

const valuesToGet = values.filter(value => (value.valueIndex != null) && (value.currentValue == null));

if (valuesToGet.length > 0) {

for (const value of valuesToGet) {

dgram = await conn.getValueById(peerAddress, value.valueIndex);

if (!dgram) {

throw new Error(`Unable to get value`);

}

value.currentValue = dgram.value;

}

}

await conn.releaseBus(peerAddress);

await conn.disconnect();

}

main().then(null, err => {

console.error(err);

process.exit(1);

});

Hi Juan,

have tried a different "changedValue" as well? "2" means "automatic mode", so there might not have been a change. You can either try "0" for "manually off" or "4" for "manually on".

Best regards,
