Energy monitoring has become an essential part of modern smart homes. Whether you want to monitor energy consumption, build automations, or optimize solar usage, reliable real-time data is critical.
We are excited to introduce two newly released Zigbee 3.0 Mini energy meters from Zemismart designed specifically for smart home integrations:
SPM01-D2TZ-U01-ZM – Single-phase energy meter
SPM02-D2TZ-U01-ZM – Three-phase energy meter
Both models support Zigbee 3.0 and can be integrated with Home Assistant through Zigbee2MQTT or ZHA, allowing users to monitor power usage in real time and build powerful automations.
These devices are designed for installation inside electrical distribution boards and provide detailed measurements including voltage, current, power, power factor, and energy consumption.
Product Overview
Single-Phase Energy Meter – SPM01-D2TZ-U01-ZM
Typical use cases include:
*EV charger monitoring
*Smart home energy dashboards
*Per-circuit consumption tracking
*Automation triggers based on power usage
Three-Phase Energy Meter – SPM02-D2TZ-U01-ZM
Typical applications include:
*Whole-house monitoring
*Heat pumps or HVAC systems
*Industrial equipment
*Large energy loads
Both energy meters use Zigbee 3.0, allowing them to work with a wide range of Zigbee coordinators.
They are compatible with:
*Zigbee2MQTT
*ZHA
Once paired with Home Assistant, the devices expose multiple sensor entities such as:
*Voltage
*Current
*Power (W)
*Energy (kWh)
*Power factor
*Temperature (device)
These values can be used directly in the Home Assistant Energy Dashboard, automations, or custom scripts.
Have you fixed the issue with this device flooding the zigbee network with messages?
The previous models were awful for this apparently.
I say “apparently” as I only heard this second hand after I ordered two of the previous model that never arrived. Your customer support was not at all helpful however I did eventually manage to get a refund.
I have a couple of these, the SPM01V2, and they also spam the Zigbee every 5 seconds with a power update. There is also a message floating around that if you update them, you can actually adjust the control on it to change this time.
You are touting Home Assistant Integration here, how about provide a way to update the firmware on these without buying a hub so that the control actually works…
Sorry for the inconvenience caused.
The Tuya version used a Tuya module designed mainly for the Tuya ecosystem. In that version, the firmware provided by Tuya did not package the data during reporting. Since the energy meter generates a large amount of data, this could sometimes lead to network congestion.
For the Zigbee 3.0 version, the firmware is developed by our own team, and we have retained the Zigbee protocol stack’s data packetization mechanism for reporting. This allows large volumes of data to be transmitted more efficiently, so we believe the same issue should not occur again.
Thanks, your feedback is very valuable to us, and I will pass it on to our engineering team for further evaluation and possible optimization in future updates. Thank you again for helping us improve our products and user experience.
Can you use the three phase version to monitor three single phase circuits? Ideally I’d like a single device that can monitor all my circuits (around 8)
I see the CE (China Export) stamp on the side in the picture. Do they have any other electrical and safety standards certification, such as FCC, either current, or planned?
Most overseas buyers (non-Chinese) may have difficulties making a purchase decision, especially if home insurance is involved with coverage in case of electrical fires voided with uncertified devices. As an ex-insurance investigator, my experience is the presence of uncertified things like this were an easy excuse to deny an electrical fire claim, hence the caution, and possible loss of sales from your end, for gaining certification is a one-off process that should be done prior to marketing and release. The one off certification cost, amortized over the product life cycle and sales volume should be very minor per device, especially as this device seems to tick a lot of boxes for the HomeAssistant community across the globe, and will be a popular device in all other aspects. Product differentiation from your competitors, on basis of certification and approvals, even for people that are extremely price sensitive, where a small cost overhead for peace of mind is an easy choice to make in your favor.
Various countries are considering import restrictions for devices that do not comply with their safety standards. This may narrow your potential global market reach considerably, and restrict sales volumes.
You are recognized as an established company and your reputation is growing. Product maturity shows in your advertising literature, product range and documentation, quality control (software and hardware), and especially integration with other ecosystems such as HomeAssistant. Can I recommend you make international standards and safety certification of your device range a corporate goal, and you may find that sales figures will boom. At the end of the day you want happy customers, repeat customers, safe customers, happy regulators, positive cashflow and most importantly handsome profits!
I have the zigbee version and I dont really like it. It’s not very accurate. It gives ± 5-6 % energy readings compared to utility companys readings. I’m most likely ditching this and getting a Shelly 3EM-63T Gen3.
The update interval (30 seconds) might be too slow? Or do I have older version I bought it last summer.
An update on external certification plans for external markets other than self certification for China and Europe would be appreciated, otherwise your global reach is being somewhat limited until this is done.
Hello,the maximum operating voltage is 240V. The 253V value refers to the insulation voltage and is not intended for normal operation. Continuous use at this level may cause premature aging or damage to the components.
Hi, I’m new to this and still can’t figure out how to update this SPM01 device (I don’t have a Tuya gateway). I’d be very grateful if someone could help. It doesn’t work with Home Assistant.
hi,you need a Tuya Zigbee gateway to pair devices with the app for updates.
If you want to work on an Home Assistance network, you can pair devices via Z2M, but you’ll need a Zigbee dongle.
Thanks for your reply. I just recently purchased the MG21 Zigbee Dongle Lite. I’m still learning how to use it.
Could you tell me what the problem is if it’s showing negative values? The sensor is installed correctly.
