Hi everyone,

Advanced filtering is now live on [heatpumpmonitor.org](http://heatpumpmonitor.org) - here’s what’s new!

1. Additional filtering operators

2. New side panel for viewing and editing filters

3. Backwards compatible with the original “filter” string

**Additional operators**

There is one additional text operator:

- Does not contain (`ne`)

The additional numeric operators are:

- Greater than (`gt`)
- Less than (`lt`)
- Greater than or equal (`gte`)
- Less than or equal (`lte`)
- Not equal (`ne`)

Anything else defaults to equals (the original behaviour).

The format is backwards compatible and works in URLs:

- all previous query strings will work as before
- mixed default (equals) and new operator: `query:hp_output:5:gt,UFH:0` (output to be greater than 5, UFH quals to 0)

Other examples:

- `query:hp_output:5:gt,UFH:0,old_radiators:1,combined_cop:4:lt,combined_cop:3:gt`
- `query:hp_output:5:gt,UFH:0,old_radiators:1,combined_cop:4:lt,combined_cop:3:gt,combined_flowT_mean:35:lt`

You can also specify ranges, e.g.:

- `query:combined_flowT_mean:35:lt,combined_flowT_mean:33:gt`

**New “Filters” panel** (here is a view without any filters - notice the “Filters” box below “Add fields”):

**Adding a new filter** (after pressing the big “+” button; selecting a column using a dropdown or typing in the name)

**Entering a value** (typing it in or picking up an existing value)

**Viewing active filters**

**Editing an existing filter** (after pressing the yellow edit button)

**Disabling a filter** (using the checkbox)

That’s all I think.

Big shoutout to the team for building such a solid foundation and making [heatpumpmonitor.org](http://heatpumpmonitor.org) so easy to extend!

Please give it a try and let us know what you think! Keen to hear your feedback and ideas for improvements.

Kind regards,  
Kamil

Hi Kamil,  
Many thanks and I don’t want to appear pedantic, but in a couple of places in [heatpumpmonitor.org](http://heatpumpmonitor.org) there is the word “seperation”.

This may be a reserved word that I’m not aware of, but if not, the common spelling is “separation”.

All the best, David.
