Building influxdb with a dedicated package set can be tricky since go is quite bitchy about its path variables and will produce really strange error messages when these are not set properly. This short memo assumes gvm and the relevant go version are already installed.
This assumes we use a folder go in $HOME to manage all go projects in a dedicated package environment
// Wait for both messages to arrive
// Calculate delta between consumption and PV
context.power = context.power || {};
switch (msg.topic) {
case 'power_cons_sum':
context.power.cons = parseInt(msg.payload);
//node.warn("context.power.cons " + context.power.cons);
msg = null;
break;
