Energenie MiHome component

[andrew.vint]

Wonder if anyone can help me out, I have a number of Energenie Mi|Home switches and sockets and though I have managed to use the API to send the on/off commands I am struggling to get the current state … below is an example of my code;

Energenie Mi|Home Integration

switch:

• platform: command_line
  switches:

  Lights

  downstairs_bathroom_light:
  command_on: ‘curl -u “user:password” -X POST -H “Content-Type: application/json” -d “{“id”:54965}” https://mihome4u.co.uk/api/v1/subdevices/power_on’
  command_off: ‘curl -u “user:password” -X POST -H “Content-Type: application/json” -d “{“id”:54965}” https://mihome4u.co.uk/api/v1/subdevices/power_off’
  command_state: ‘curl -u “user:password” -X POST -H “Content-Type: application/json” -d “{“id”:54965}” https://mihome4u.co.uk/api/v1/subdevices/show’
  value_template: ‘{{ value_json.data.power_state == 1 }}’
  friendly_name: “Downstairs Bathroom Light”

Now the on/off works … but I get the following error in the logs for getting the current state;

2019-02-11 09:26:50 ERROR (MainThread) [homeassistant.helpers.template] Error parsing value: ‘value_json’ is undefined (value: None, template: {{ value_json.data.power_state == 1 }})

Anyone able to shed some light on this ?

It looks like the options for RF control from HASS on a Pi 3 (via venv) are a Pi-mote vs an RFLink arduino kit with pre-soldering from Nodo Shop. I have some questions please:

Using @gpbenton 's engMQTTClient, how do you find the IDs of the devices? Do the Energenie light switches have OpenThing IDs printed on them somewhere?

Will the Pi-mote work with other (non-Energenie) 433mhz devices? e.g. these: https://www.ebay.co.uk/itm/Wireless-Remote-Control-Kinetic-Self-powered-No-Battery-Wall-Light-Smart-Switch/382652254199?hash=item5917da07f7:m:m-Pl97IT0CL-nGCU2cckqMA&frcectupt=true
If so, is there a UI in HASS to find the switch’s ID? I hear there’s a lot of background 433 traffic in UK cities.

Same questions for the RFLink setup - can you use HASS to find the IDs of the Energenie switches and kinetic switches?

Thanks

@mamoulian

Do the Energenie light switches have OpenThing IDs printed on them somewhere?

The energenie devices work on two different protocols. The switches and sockets are receive only and use a standard 433MHz protocol. These can be used with most 433MHz decode/encode diy kits, including RFLink and OpenMQTTGateway. This is not the OpenThings protocol.

Other Energenie devices are two way, such as the eTRVs and Energy Montoring devices. These use the OpenThings protocol and FSK modulation, and are not controllable with normal 433MHz controllers.

My engMQTTClient spends most of its time listening for OpenThings messages using FSK encoding, but switches to OOK when it receives an MQTT message to send a signal to a switch, so effectively works with both.

@mamoulian

Will the Pi-mote work with other (non-Energenie) 433mhz devices?

I do use some Sensoo light switches I got from AliExpress with the PiMote, but I was surprised they worked, and can make no guarantees about any other 433MHz devices. There are sublte differences about the way each of them works.

@mamoulian

Using @gpbenton 's engMQTTClient, how do you find the IDs of the devices? Do the Energenie light switches have OpenThing IDs printed on them somewhere?

As explained above, the light switches are receive only and do not use OpenThings and so do not have an ID. The devices using Openthings broadcast periodically with their ID and this is received by engMQTTClient and sent over MQTT. The MQTT topic contains the OpenThings ID.
You program the light switches (I assume, I don’t have any Energenie Light Switches) like most 433MHz switches by holding down a button for a few seconds until an LED flashes, and then sending a signal to it from a remote (or PiMote).

[mamoulian]

Thanks very much for the explanation!

@gpbenton

You program the light switches (I assume, I don’t have any Energenie Light Switches) like most 433MHz switches by holding down a button for a few seconds until an LED flashes, and then sending a signal to it from a remote (or PiMote).

Ah thanks, I didn’t know that. So if using a PiMote from software you can effectively just send ‘any code’ and as long as it’s the first code the switch receives it stores it? Is there a HASS UI for that? If not what tools do you use? How does programming work if there’s a lot of background 433mhz traffic in a city environment?

@gpbenton

Do you send signals to those using engMQTTClient too?

[gpbenton (Graham)]

@mamoulian

So if using a PiMote from software you can effectively just send ‘any code’ and as long as it’s the first code the switch receives it stores it?

The switch can store two different codes, so you can use two different remotes to control it. You can make up codes for use from the PiMote, but there are rules that have to be met in the signal. I think I found out what they were when I was writing engMQTTclient, but I have long since forgotten. I may have them written down in the documentation. I listen for the remote code and just use that.

I use OpenMQTTGateway to listen for signals, but any 433Mhz snooper should do the job.

@mamoulian

Is there a HASS UI for that?

Not directly, but if you configure a switch to send the code, it will be sent . when you turn the switch on.

@mamoulian

How does programming work if there’s a lot of background 433mhz traffic in a city environment?

I can’t help there, I live in a rural market town. But the signal strength is attenuated by walls, and there are plenty of codes, so I don’t think it would be a problem.

@mamoulian

Do you send signals to those using engMQTTClient too?

Yes, and I was surprised it worked. I just copied the code the the remote sent and used it in the MQTT message, but there is no guarantee it will work for anything else. There are different protocols used by different manufacturers, and not all of them are compatible.

Hi Steve you seem to be the go to man on the home assistant, energenie, command line subject and wondered if you could cast any light on my problem?
I have an energenie thermostat which i can switch on and off in home assistant with the code below

- platform: command_line
    switches:
      greathall_thermostat_switch:
        command_on: 'curl -u "username@password" -X POST -H "Content-Type: application/json" -d "{\"id\":188722}" https://mihome4u.co.uk/api/v1/subdevices/power_on'
        command_off: 'curl -u "username@password?" -X POST -H "Content-Type: application/json" -d "{\"id\":188722}" https://mihome4u.co.uk/api/v1/subdevices/power_off'
        #command_state: 'curl -u "username@password?" -X GET -H "Content-Type: application/json" -d "{\"id\":188722}" https://mihome4u.co.uk/api/v1/subdevices/show'
        #value_template: '{{ value_json.data.power_state == "1" }}'
        friendly_name: Greathall Thermostat Switch

As you can see i have hashed out the command_state and value_template as these are not returning the state of the relay and make the switch return to off after it is switched on.
Any help appreciated

[stevenhorner]

Apologies for not replying I haven’t done much with Energenie for a long time. I’m guessing you are trying to do a switch that turns on and off your thermostat which is the part that is uncommented.
I think the part that is commented should actually be a sensor not a switch.

Try adding it as a sensor, something like this:

sensor:
  platform: command_line
  command: 'curl -u "username@password?" -X GET -H "Content-Type: application/json" -d "{\"id\":188722}" https://mihome4u.co.uk/api/v1/subdevices/show
  name: Greathall Thermostat State
  value_template: '{{ value_json.data.power_state == "1" }}'

[woollatt]

Thanks for the response steve i had got a sensor setup already but it didnt work with the command_line switch, but it does work with the template switch with the following

- platform: template
    switches:
      energenie_greathall_thermostat_switch:
        friendly_name: Energenie Greathall Thermostat Switch
        value_template: "{{ is_state('sensor.greathall_thermostat_switch_state', '1') }}"
        turn_on:
          service: switch.turn_on
          data:
            entity_id: switch.greathall_thermostat_switch
        turn_off:
          service: switch.turn_off
          data:
            entity_id: switch.greathall_thermostat_switch

Why have energenie not done a Home Assistant component yet?

It would make their products far more desirable!

Hello All

I am still struggling with programming an automation or slider to adjust the temperature of a mihome thermostat

I have the code below which will change the temperature to 25 , howerver how do i incopeate a slider into the code to adjust te temperature

Any Help greatly recieve

paul

`curl -u "YOURUSERNAME;:YOURPASSWORD" -X POST -H "Content-Type: 
application/json" -d "{\"id\":146015, \"temperature\":25.0}" 
https://mihome4u.co.uk/api/v1/subdevices/set_target_temperature`

[itm1960]

I’ve been using the HTTP POST commands as posted by StevenHorner further up this thread (thanks!). However I’ve noticed that the switch on/off commands are no longer working in ny HA setup. I can still turn them off from the Energenie web console, and have re-checked my device ID’s against the Energenie console, but my Home Assistant commands are no longer triggering the switches.
Here’s an example of one of my commands (with id’s substituted):

study_switch:
        command_on: 'curl -u "[email protected]:mypassword" -X POST -H "Content-Type: application/json" -d "{\"id\":12345}" https://mihome4u.co.uk/api/v1/subdevices/power_on --insecure'

Is anyone else having problems with this at the moment?
I’m running an HA 0.65.0

[bellringer2]

Hi Steve,

Can I add my thanks to others for your examples?

I am becoming more and more sold on HASS due to the wonderful helpful community including guys like you.

Best regards Peter

Is it possible to get the current state of energenie switches such that the HA UI shows the correct state?
I’m pretty new to this but using the mihome api and the curl command as described above I have my light and plug switches working in that I can turn them on/off. (So thanks for the info) But, if the switch is triggered by something else, say I actually press the physical button, the HA UI becomes out of sync - even when refreshed. I know there is a api to get current state, but is it possible to integrate this into HA Ui some how?
Thanks

[sdavis8991]

Thank you!
I accidentally bought one of these thinking it was tuya-based, and at least I can control it for the few weeks I need it and then can send it back when I can access my already tasmotised plugs.

I was using a APIRequest.io to get the details but it kept responding “not found” when controlling devices, but your command just worked as soon as I put in the details.

[Decker (Edmund Ford)]

Hi Paul,

I also have the eTRVs. Did you manage to work out how to parameterise set_target_temperature call with slider or other selection?

I have the below from @stevenhorner working.

curl -u “:” -X POST -H “Content-Type: application/json” -d “{“id”:54321, “temperature”:25.0}” https://mihome4u.co.uk/api/v1/subdevices/set_target_temperature

Many Thanks

Rest

I have got this working with the Rest sensors etc, I will post all the code shortly.

[Richard.Huish]

WORKING EXAMPLE BELOW

Sorry for the delay, I have not completed the full switch yet (will post once complete), but here is the code to get power measurement from the MiHome Smart Plug MIHO005 and MIHO004 and add them to the “Energy” page of home assistant. Using “rest” and “integration” platforms.

The platform: integration will show up in “/developer-tools/statistics” and can be added via “/config/energy”

Set username, password and payload ID (for your switch/sensor) as appropriate.

Update: I’ve now finished the complete configuration and it’s available here:

Example: Energenie MiHome control and energy monitoring via REST API https://mihome4u.co.uk/

Please find below my working code for controlling and pulling data from the Energenie MiHome range of smart plugs / switches. (For those unfamiliar with github you can use this link to download the latest folder: Download Link) The templated switches are dynamically updated from the Energenie API, so they reflect the status of the switches even if you turn them off manually at the wall or via other means such as remote control or their website. The measured wattage is retrieved and used as…

Hi All very new to home assistant i have about 8eTRV and verious light switchs and sockets and they all connect the Energnie hub and for many years have work great. to start with all i want is to be simple be able to record the temperature in home assistant but i cant find a simple solution to follow. I am also using an old pc to power Home assistant.

[paullayton (Paul)]

Someone please help before i go out of my mind here
this must be a simple mistake i am making
in my configuration.yaml file i have this

#background: var(--background-image)
history:
logbook:
# Configure a default setup of Home Assistant (frontend, api, etc)
default_config:


sensor:

  - platform: command_line
    command: 'curl -u "login :password" -X POST -H "Content-Type: application/json" -d "{\"id\":356528}" https://mihome4u.co.uk/api/v1/subdevices/show'
    name: mbs_radiator
    unit_of_measurement: °C
    value_template: '{{ value_json.data.last_temperature }}'

`
If I do the curl command I get the data back
When i test it in home assistant it says no errors, but when i run it, i get no entity?
