Hey all!
It would be pretty cool to control this heated mattress pad with Home Assistant. You could do so much with it to improve these chilly winters! I do not see public API documents but they may be available. I will try reaching out to the company.
Iāve figured out that is has port 6668 open and the iPhone app can talk to this directly.
The iPhone app first tries Bluetooth, then using the local LAN and then finally the cloud. In order to observe it I has to disable Bluetooth, enable airplane mode, disable WiFi and use an Ethernet connector for the iPhone to go into a cable where I have a packet capture device connected into PC running wireshark.
It seems each command causes 4-6 round trip messages. The messages are binary. If I use the iPhone to turn it on twice, the two packers sent have several differences.
For the cloud interface, they appear to be encrypting or encoding the JSON within the API calls.
I may try replaying the packets to the IRC port to see if they work a second time.
So far itās not looking very easy.
Based on their DNS hosts, I believe Sunbeam is using this: https://www.tuya.com/
Hence there is likely documentation for the APIs since they are using and hosted by Tuya. It should also be well implemented and highly secure.
This looks like a good start
and it appears there is an HA integration that is officially supported by Tuya.
So i think the approach is to see if the Sunbeam device that is using Tuya is accessible from the broader Tuya ecosystem
I have a king size Sunbeam heated mattress pad that I was able to set up in Home Assistant with full control after a few hours of experimentation. I would expect the queen size pad with dual heat zones to require the same setup. Here are the high level steps I went through to get it working:
- Sunbeam uses Tuya so you need to register the mattress pad in the Smart Life app instead of the Sunbeam app. If you already registered in the Sunbeam app just re-register in the Smart Life app and it will work fine (that is what I did). To register in Smart Life: (+) ā Small Home Appliance ā Electric Blanket (Wi-Fi). Long press the ācheckā button on the controller to enter pairing mode. Follow the app prompts. Verify you can control it from Smart Life. The device control screen in Smart Life should look identical to the screen in the Sunbeam app. You can uninstall the Sunbeam app at this point.
- Install LocalTuya in HA if you do not already have it.
- Add a new integration for LocalTuya and choose the ID of your heated mattress. Use the GUI to input the entity control mappings shown below. For a single zone heated mattress, you probably only need the master controls and can exclude the side A/B mappings. Or maybe use Side A only. I am not sure since I do not have a single zone heated mattress pad to test with.
- Test that it works then add the controls to Lovelace. It should provide full control with real-time updates to switch status, heat levels, etc.

Thank you for your instructions! What entity type did you choose when adding the blanket to Local Tuya?

You will have to set each one of the settings. I started from the top and copy and pasted for each value.
Hero! Thanks for sharing this. I just added my heated blanket to home assistant, but I found adding the entities in the localtuya integration configuration to be a PITA so I added them via configuration.yaml. Posting this here in case someone else finds it useful.

I spent some more time making this nice for my dashboard!
I didnāt like having the heat level as a drop down and prefer using numberbox-card since it has +/- signs and allows for a smaller footprint in the card. In order to do this, I added an input number helper called input_number.side_a_heat_level with a min of 1 and a max of 10. I then created the following two automations:
alias: BED_Set heat level for Side A
description: ''
trigger:
- platform: state
entity_id: input_number.side_a_heat_level
condition: []
action:
- service: select.select_option
data:
option: '{{ (states.input_number.side_A_heat_level.state | int) }}'
target:
entity_id: select.side_a_heat_level
mode: single
alias: BED_Set Side A input number to match manual heat level change
description: ''
trigger:
- platform: device
domain: select
entity_id: select.side_a_heat_level
type: current_option_changed
condition: []
action:
- service: input_number.set_value
data:
value: '{{ (states.select.side_a_heat_level.state | int) }}'
target:
entity_id: input_number.side_a_heat_level
mode: single
Repeat for Side B.
I also noticed that preheat wasnāt working as it should (it was just setting level to 10/H and not going back down after 30 minutes) so I added an automation that fixes this and also allows me to manually set the preheat time. This will require an input boolean (e.g. input_boolean.preheat_side_a). Automation below.
alias: BED_Preheat Side A
description: ''
trigger:
- platform: state
entity_id: input_boolean.preheat_side_a
to: 'on'
condition: []
action:
- service: scene.create
data:
scene_id: side_a_before
snapshot_entities: select.side_a_heat_level
- device_id: xxxxxxx
domain: select
entity_id: select.side_a_heat_level
type: select_option
option: '10'
- delay:
hours: 0
minutes: 30
seconds: 0
milliseconds: 0
- service: scene.turn_on
data: {}
target:
entity_id: scene.side_a_before
- service: input_boolean.turn_off
data: {}
target:
entity_id: input_boolean.preheat_side_a
mode: single
Lastly, I added a horizontal-stack card in Lovelace, as follows:
type: horizontal-stack
title: Heated Mattress Pad
cards:
- type: entities
title: Side A
entities:
- entity: switch.side_a_power
name: Power
- entity: input_number.side_a_heat_level
name: Heat Level
type: custom:numberbox-card
- entity: input_boolean.preheat_side_a
name: Preheat
- entity: select.side_a_set_timer
name: Timer
- type: entities
title: Side B
entities:
- entity: switch.side_b_power
name: Power
- entity: input_number.side_b_heat_level
name: Heat Level
type: custom:numberbox-card
- entity: input_boolean.preheat_side_B
name: Preheat
- entity: select.side_b_set_timer
name: Timer
Hopefully this comes in handy for someone in the future

Iām still experimenting on a guest bed, there are some Home Automations the significant other will not accept without 100% reliability, and Iām not there yet. Local Tuya control is still perplexing to get solid. The gold standard for this device will be for the automation below to work all the time, Iām only at about 70% currentlyā¦

- platform: state
entity_id: sensor.small_bedroom_sunbeam_bedding_preheat

Really great info. Used your configuration,yaml and it just works. Thanks for sharing!! There is a lot of outdated information on how to get the device key as Tuya keeps changing stuff. Best reference is here, which is also linked from the integration home page

Iām probably limiting myself here, but I am not using the LocalTuya integration currently, but rather coding my own MQTT devices using this fantastic python library by Jason Cox, TinyTuya, link below. If for not for any other use, try it to help you get your brain around the Tuya data points, types and ranges. Tuya devices are real wild west, IMHO. However, this space is where many/most of the interesting/useful home automation devices are running. Case in point, this electric heating pad, not going to find that in the zigbee world!
Iām not sure the Tuya world is going to get anymore āfriendly/standardized/consistentā to the Home Assistant world. However, if there is software like the HA LocalTuya integration and LocalTuya that gives us opportunities to control some of these devices completely locally, that is good progress.
Good hunting!
ellaizee, your yaml config has worked great and I can control my mattress pad via HA, but Iām running into one problem that I canāt get past. On the second automation you listed, āBED_Set Side A input number to match manual heat level changeā, I get the following error when trying to save that automation:
Message malformed: required key not provided @ data[ādevice_idā]
I also tried going to developer tools >> services and calling this service via YAML mode:
service: input_number.set_value
data:
value: ā{{ (states.select.side_a_heat_level.state | int) }}ā
target:
entity_id: input_number.side_a_heat_level
And when doing that I get this error:
Failed to call service input_number.set_value. required key not provided @ data[āvalueā]. Got None
I tried putting your template value into Developer tools >> template and I get back ā1ā.
Iām not sure what Iām doing wrong. Any ideas?
Thanks!
Got it figured out. Had to add device_id to the trigger section and dug that out of core.entity_registry.
Fantastic instructions ā thank you.
There appears to be a āsafety featureā that reduces the temperature down to 5 (if previously higher) when turned on remotely (Alexa, or LocalTuya API). This can be dismissed only be pressing the checkmark on the physical mattress controller within an hour of turning on the pad (the checkmark slow blinks to remind you). Is there any way around this aside from an automation that turns the bed off at 59min and back on to (for example) level 8 a minute later?
FYI: As of LocalTuya v4.0.0, configuration using YAML files is no longer supported. Unfortunately the tip from ellaizee no longer works and configuration from the UI is necessary.
I created a workaround for this issue using a Home Assistant scheduled automation. I found that by changing the mattress pad timer value every hour, it is possible to avoid the auto-off feature indefinitely. Changing the timer value will not turn the heater on if it is off. I have mine scheduled to run all the time. This is the automation configuration I use:
platform: time_pattern
hours: '*'
device_id: {device_id_here}
domain: select
entity_id: select.side_a_set_timer
type: select_option

Iāve not found this to work.
Baseline: I tested setting the mattress heat to level 8 (via HA) and left it. After 1hr it reduced to level 4.
Proposed solution: I then tested setting the mattress heat to level 8 (via HA) and after 30 minutes I changed the timer (Tuya ID 27), via HA, from 10hrs to 24hrs. After 30 more minutes (1hr total) the mattress heat still reduced to level 4.
After continued testing Iāve still been unable to get the workaround suggested by MrWhite49 to work.
My solution has been to save the state at 55 minutes, power off the master power (both sides) and I can immediately restore those states, thus resetting the 1 hour safety timer. I plan on wiring this up through NodeRed so I can apply logic such as pre-heat at level 10, then maintain level 7 for 3hr, then reduce to level 5 for the remainder of the night, turning itself off in the morning.

Any progress with this in your Node Red build?
I also am getting the same error. If I figure it out I will post the answer here.
