Is anyone creating a GivEnergy binding?

Mink2781 · January 16, 2023, 3:51pm

Hi - I’m new to OH3 and automation in general. Got most of my devices up & working within OH.

I’m expecting to have a GivEnergy PV & battery system (UK) installed in a few months time and am looking at what data I’ll be able to get from the system to use within OH.

Before I go much further looking into how to use their API (and in fact any API as I’ve not done this before ), I was wondering if anyone is developing a GivEnergy binding?

Cheers
Mike

GivEnergy have an API that I think you can access with HTTP, either the binding or in a rule.

I’m not sure how often that is updated so I use a local connection. The GivEnergy WiFi dongle accepts Modbus over TCP connections. Annoyingly, they don’t use the standard Modbus protocol so you can’t use the Modbus binding. There is a program called GivTCP that you can execute with the exec binding and parse the results with a rule or a JSON transformation. I use this method to poll the inverter every 10 seconds.

I did modify GivTCP to grab fewer parameters because it was filling up the log with long JSON strings.

Thanks for the info.
I’ll bear this in mind once I have the system installed etc.

If it helps, I’ve just helped integrate a GivEnergy battery system into openHAB (no solar PV though) via the cloud API. We used the HTTP Binding and JINJA Transformation Service, with the following text configs:

At some point I intend to be able to change the charge and discharge times from within openHAB, but haven’t investigated yet.

Do you fancy sharing how you set this up and configurations? We’d like to eventually move off the cloud API!

I’m sure this will help - many thanks.
I’m a complete beginner but I’m sure I’ll find this info invaluable.
I’m still waiting to have the system installed so can’t even experiment yet.

barneyd · March 7, 2023, 8:47am

The key to this is a program called GivTCP, which is available on GitHub. I use the Exec binding to run the program every 5 seconds. It returns a JSON array of values representing the inverter status registers that is captured by the exec binding. I then use a rule to extract the values that I want because as far as I know, you can’t apply transformations to exec channels. I ended up modifying GivTCP to reduce the number of values returned because every instance of the array ends up in the OpenHAB log.

The external program would be unnecessary if the inverter used the standard Modbus protocol but annoyingly it has some sort of preamble that means the standard Modbus binding can’t get a response.

Since I did my installation, GivTCP can now publish to an MQTT broker, which might be a neater way of using it.

hafniumzinc · March 7, 2023, 8:55am

OK, great - I saw that yesterday, and it looks like they have a Docker image which redirects the data to an MQTT broker which would work perfectly for us (no rules required!)

EDIT: @barneyd FYI the previously linked repo is essentially dead. It provides a docker-compose.yaml pointing to britkat1980’s image, but the example isn’t compatible with that image. Best use britkat1980’s repo directly at GitHub - britkat1980/giv_tcp: TCP connection (from inverter) and MQTT implementation, which has commits from 3 days ago, rather than 7 months ago.

hafniumzinc · March 9, 2023, 8:37pm

I have now switched over from the cloud API with the HTTP Binding to the local Modbus via MQTT using GitHub - britkat1980/giv_tcp: TCP connection (from inverter) and MQTT implementation.

@barneyd this may be interesting for you, as it doesn’t require extra rules, nor an extra service (MQTT, if you don’t already use it…).

barneyd · March 18, 2023, 1:24pm

Thanks for sharing. I guess it comes down to running a service that interacts with the inverter and makes the parameters available to http or MQTT or running a program to interrogate the inverter directly.

Shame they couldn’t just use standard Modbus!

I’m having trouble with commands. GivTCP theoretically provides the means to control the inverter but I haven’t managed to get it working.

hafniumzinc · March 18, 2023, 5:57pm

The thing is, the ‘service’ and the ‘program’ are the same thing here: giv_tcp. You either do

inverter ↔ giv_tcp ↔ exec binding ↔ rules ↔ openHAB items

or it’s

inverter ↔ giv_tcp ↔ HTTP binding ↔ openHAB items

or it’s

inverter ↔ giv_tcp ↔ MQTT broker ↔ MQTT binding ↔ openHAB items

But yeah, it would be slightly more efficient if we could do

inverter ↔ modbus binding ↔ openHAB items

I’ll share any successes or failures!

Can anyone assist me with this installation?

I’m looking at using MQTT (rather than API) and so I’ve added the things and items files to OH (as @hafniumzinc details above) -
adjusting the data for my inverter serial number and the MQTT ID in place of ‘mosquitto’

like this:

Thing mqtt:topic:52ca13ce9e:givenergy-power “Generic MQTT Thing - GivEnergy Power” (mqtt:broker:52ca13ce9e)
and everything appears within the UI.

I have MQTT broker working in OH and assumed that I’d need to create generic MQTT brokers for Power, Energy, Timeslot & Settings.
I’ve done this and all show as online.
Britkat states: ‘For Invertor autodiscovery to function your container must run on the “Host” network within docker (not Bridge)’.
Does this mean that using a generic MQTT broker is incorrect?

Referring back to Britkats github instructions, it recommends installing using Docker. So I’ve installed Docker, changed the various parameters in docker-compose.yml and put the .yml file in the getting-started directory (I assume this is correct as there was already a ‘blank’ file there).

I use the command: ‘docker compose up -d’ and get various build messages etc ending with container started. Looks good so far.

How can I tell if it’s working? Running MQTT Explorer doesn’t show me any GivEnergy data, only the MQTT stuff I already have running.
Nothing in OH UI is showing any data, only NULL.

Any help would be appreciated.

hafniumzinc · May 5, 2023, 5:04pm

No, you only need one MQTT Broker/Bridge Thing total within openHAB, which will communicate with your external MQTT broker. Generic openHAB MQTT Things (as shown in my post) will then talk to your external MQTT broker via the openHAB Broker/Bridge Thing.

Do you have an external MQTT broker setup?

Well, this needs fixing first before doing anything with openHAB. For some reason, your external MQTT broker is not receiving any communications from your Docker container.

What operating system is this all installed on?

Mink2781 · May 6, 2023, 5:52am

I’m running on a RPi, with Raspian.

Re the broker - I have a broker installed in OH (it has the IP address set the same as my Pi - is this what you mean by external?). Then I’ve got generic brokers talking to the broker for stuff like my tuya lights and switches etc. This is running fine.
I presumed that I’d need to create generic MQTT things via the broker/bridge Thing for the GivEnergy stuff, just like I do for other MQTT Things (like tuya lights etc). I could be wrong.

So sounds like it’s ‘your external MQTT broker is not receiving any communications from your Docker container’ that could be the problem.

I’m now slightly (!) confused - having done this:

docker pull britkat/giv_tcp-ma

Britkat suggests creating a container for the various ENV stuff. I’m not sure I’ve done that. The only container I can see is ‘openhab’. How do I create a container or access the Britkat container? - I tried to create one called GivEnergy but get this message:

Unable to find image ‘givenergy:latest’ locally
Error response from daemon: pull access denied for givenergy, repository does not exist or may require ‘docker login’: denied: requested access to the resource is denied

As you can probably tell I’ve got no experience with docker.

hafniumzinc · May 6, 2023, 6:20am

What version of openHAB do you have?

I’m not sure what any of this means. I have one compose file, and just do docker compose up within the folder that contains the compose file - this enables me to see the logs to check if everything is working.

For me, my MQTT Broker is running on a device at 192.168.1.212, whilst my giv_tcp container is running at 192.168.1.215. Sounds like in your setup these two addresses will be the same - your Pi.

My givEnergy invertor is at 192.168.1.95.

Mink2781 · May 6, 2023, 9:21am

@hafniumzinc I do appreciate your help with this.

I’m running OH 3.4.3.

So as I understand it, the docker compose up starts the container (I happened to have put the compose file in docker-giv directory.
When I run that, I get this:

Container docker-giv-GivTCP-1 Recreated
Attaching to docker-giv-GivTCP-1
Error response from daemon: driver failed programming external connectivity on endpoint docker-giv-GivTCP-1 (f331d4421c740571fc9087369249fc7e499b12c84f2c719a6e8c6f07fd0c272a): Error starting userland proxy: listen tcp4 0.0.0.0:1883: bind: address already in use

hafniumzinc · May 6, 2023, 11:31am

OH3 doesn’t come with an embedded MQTT broker. Did you install Mosquitto on your Pi?

Mink2781 · May 6, 2023, 1:05pm

Yes I installed Mosquitto. MQTT Explorer screenshot shown here:

As you can see I have numbers of Things connected via the broker. These are via generic MQTT brokers/bridge etc. and all show real time data.

I susepct that the problem is around the docker install etc. In the error message I showed earlier, it says ‘bind: address already in use’. Any idea what that means?

Also do I have this correct within the Things file?

Thing mqtt:topic:52ca13ce9e:givenergy-power "GivEnergy Power" (mqtt:broker:52ca13ce9e)

hafniumzinc · May 6, 2023, 1:07pm

It looks like it’s trying to start up its own MQTT broker. I think there are some container images which had that option, but didn’t think the latest ones did…

Mink2781 · May 6, 2023, 1:25pm

Ah OK.
I used docker pull britkat/giv_tcp-ma. Is there something else I should have done?
I don’t know how to choose a different container image.
