TP-Hyperlink Kasa Good Thermostatic Radiator Valve KE100 KIT Evaluate – A superb reasonably priced good TRV that now works with Tapo [2024 Update]

[Update – 12th February 2024] I initially wrote this evaluation again in December 2023 and criticised this TRV as a result of mess that was the Tapo and Kasa interoperability.

I expressed annoyance that the Kasa good hub had the identical {hardware} because the Tapo good hub, however you couldn’t add the KE100 to the Tapo hub, but if you wish to use the KE100 with sensors, you’d should pair up Tapo sensors with the Kasa hub.

Since then, TP-Hyperlink has fastened this downside. Within the Tapo app, when you choose add system, now you can toggle to Kasa and add the KE100 to the Tapo hub.

Moreover, Tapo has up to date the Tapo H100 Hub to help Matter, whereas Tapo had beforehand instructed the Tapo H100M was a distinct piece of {hardware}.

This, due to this fact, modifications my general possibility of the KE100 considerably. I assumed it was a superb good TRV within the first place as a result of low worth it was obtainable for, however now it really works with Tapo correctly and has Matter help, it could be top-of-the-line choices available on the market when you don’t want the boiler management options that manufacturers like Tado and Genius Hub present.

I’ve all the time been a fan of TP-Hyperlink for each their networking {hardware} and the good dwelling units.

For sure, the TP-Hyperlink Tapo and Kasa good plugs are my favorite good plug socks I’ve used. I’m within the strategy of reviewing the brand new ‎Tapo P110M matter-enabled plug, and I feel this or the beforehand none-matter P110 are the best smart plugs available on the market as they’re extraordinarily reasonably priced and have vitality monitoring, which is an effective way to observe what electronics use probably the most electrical energy.

I’m additionally a large fan of smart thermostatic radiator valves. I work at home and stay in an previous, inefficient dwelling, so controlling the heating on a room-by-room foundation can save a whole bunch per yr in heating prices.

Due to this fact, I used to be fairly excited once I noticed that TP-Hyperlink Kasa had launched their very own KE100 Good Radiator Thermostat.

For the January replace, the value of the valve by itself is £35 on Amazon UK, with the bottom worth being £27 again in November. You possibly can then get the Tapo H100 good hub for simply £15.

Alternatively, the TP-Hyperlink retailer has the Kasa KE100 KIT for £45.

TP-Hyperlink Kasa and Tapo was a large number of a sensible dwelling ecosystem

TP-Hyperlink began off with Kasa and later launched Tapo. It appeared like an odd factor to do at first, however the thought was that Kasa could be the premium vary and Tapo the reasonably priced vary, which is one thing I used to be OK with, and it appeared to make sense.

Over time, the variations between the 2 manufacturers blurred, and it turned more and more irritating that there have been two separate apps for units that do the identical factor all from the identical primary model.

Again in March 2022, I used to be informed:

TP-Hyperlink is engaged on an integration between Kasa and Tapo into one app to verify there may be continued performance for each merchandise units collectively as Kasa goes finish of life.

That was speculated to occur in Q3 2022, however they lastly rolled out the mixing in November 2023.

TP-Hyperlink appears to have modified its thoughts about Kasa because it has continued to launch units below this model, together with this KE100 good TRV.

No downside. The 2 ecosystems work collectively now. However it isn’t fairly so simple as that.

Once I initially reviewed this in December 2023, the Tapo app didn’t but help the administration of the KE100 / KE100 Equipment, and there have been additional integration issues.

This has now modified, and the KE100 is supported inside Kasa and Tapo and can be utilized with the Tapo good hub.

The Kasa/Tapo scenario remains to be a little bit of a complicated mess however it’s considerably higher than it was.

Identical hub {hardware}, no cross-compatibility

TP Link Kasa vs Tapo Hub 1

Initially, I impulsively purchased the KE100 with no hub with out studying the outline that claims it requires a hub. I attempted to put in it, pondering I might combine it with the Tapo H100 hub, however this didn’t work in any respect as a result of above lack of help.

This has now modified, and the KE100 might be paired with both the Tapo or Kasa hub.

Tapo T110 sensors required for open window detection

Beneath the FAQs for the KE100 KIT, TP-Hyperlink states that the KE100 helps open window detection, however to do this, you want the Tapo T110 contact sensor.

The Kasa app permits you to add Tapo sensors to the hub, nevertheless it works with sensors you might have paired in Tapo with the Tapo H100 Hub. You’d should reset the sensor and pair it with the Kasa hub.

With the January replace, the KE100 might be paired with both hub and any sensors you might have will should be on the identical hub for them to combine correctly.

Matter Now Works

TP Link Matter

Within the preliminary evaluation, neither the Kasa nor Tapo hub labored with Matter. TP-Hyperlink had additionally indicated that the Tapo H100M hub could be completely different {hardware} to the Tapo H100. Nevertheless, they’ve rolled up an replace to allow Matter on the prevailing hubs.

I’ve struggled to get the hub to work correctly with Dwelling Assistant however I’ve built-in it wonderful with SmartThings and Google Dwelling with the Google Nest WiFi Pro.

Set Up & Set up

As soon as I lastly had the right hub, organising the system was easy. You need to undergo the same old steps so as to add the hub to your Kasa app. For me, this included connecting to the open SSID on the hub.

You then want to put in the TRV earlier than including it to Kasa. This has a barely completely different design to a number of the TRVs I’ve used. The highest of the TRV has a grove that permits you to twist the cap off, this then exposes the battery compartment and the small gap for reset.

The KE100 comes with varied adaptors for various radiators, however I used to be capable of mount it immediately.

With it mounted, I had to make use of the included plastic pin to carry down the reset button and start the pairing course of.

As soon as paired, the valve was calibrated, and all the things labored. I didn’t have any calibration points like I did with the Aqara TRV.

App & Settings

The settings inside the Kasa app are fairly primary, nevertheless it has the primary performance you want.

Going into the primary web page for the KE100, the inexperienced energy button allows/disables the TRV. With it disabled, it is going to enter frost safety mode and cease any schedules you might have.

The good management part is the place you arrange your schedules. It’s primarily the identical as Tado and Genius Hub. You possibly can have one schedule for the complete week, or a piece week and separate Saturday and Sunday schedules or particular person schedules for every day.

You possibly can then add as many time blocks as you need.

In case you press the cog icon, you’ll be able to allow early begin, which tells the TRV to pre-heat the room to the goal temperature in your schedule. Alternatively, it solely prompts firstly of the schedule.  

Third-Celebration Integration

With the current replace, third-party integration has been considerably improved. You continue to can’t add it to the Kasa integration on Homey, however due to Matter, you need to be capable of use it with the Homey Professional or another Matter-enabled good hub/ecosystem.

Not too long ago, some intelligent folks had been capable of get the Kasa KH100 hub and KE100 to point out up within the Tapo Home Assistant HACS. Satirically, the official TP-Hyperlink Kasa integration can’t see the hub or TRV.


Because of all the constraints, there may be not a lot to write down about the way it has labored since I put in it. It really works as marketed; it comes on primarily based on my schedule, and I haven’t observed it being excessively noisy like some valves.

Throughout the app, there’s a good report web page, which reveals a graph of the temperature of the room for every day. The graph reveals some small orange strains which signifies the schedule and goal temperature, which I feel is kind of helpful.

In case you simply need primary good management over your radiator, then it is a completely good possibility.

Worth and Different Choices

[amazon box=”B0BKQWGSMC,B0BC6KN2DK” template=”table” filterby=”price”]

The Tapo retailer has the KE100 KIT listed at an RRP of £80, with the person valves being £60.

That makes the Kasa TRV across the similar worth as valves from Hive, Tado (the fundamental valve), and Honeywell. The Aqara Smart Radiator Thermostat E1 has an RRP £50, cheaper at £55.

On the RRP, I’d strongly advise in opposition to investing within the TP-Hyperlink Kasa KE100 TRVs. The one promoting level is that the KE100 KIT is cheaper than the Tado Smart Radiator Thermostat – Starter Kit V3+, which has an RRP of £130. Tado could also be dearer upfront, however it’s a vastly superior system, and you’ll improve to full good dwelling heating management with their Wi-fi Good Thermostat Starter Equipment with Scorching Water Management.

I choose the KE100 to my Aqara Good Radiator Thermostat E1 valves. The scheduling and app are higher, however Aqara has a lot better third-party help, together with Dwelling Assistant.

Nevertheless, the Tapo KE100 / KE100 KIT are not often at full worth. On the time of the unique evaluation, the KE100 KIT, was £30.95 from the 17th to the 28th of November, and the KE100 by itself was £27. That will make the Tapo KE100 / KE100 KIT the most affordable good radiator valve available on the market by a substantial margin, which makes up for all its shortcomings.

On the time of writing, the SONOFF Zigbee Thermostatic Radiator is the one different reasonably priced good TRV (from a good model) priced at £35.


I purchased the Tapo KE100, pondering it will be a fast evaluation, and I might find yourself strongly recommending it as a result of extremely enticing pricing. I used to be mistaken.

I had vital points with the Tapo KE100 as a result of lack of Kasa/Tapo compatibility, however this has now modified, and also you additionally get Matter help.

A dumb thermostatic radiator valve will usually value between £10 and £20, so it appears effectively price it to spend a bit further on the Tapo KE100, you’d seemingly recoup the price in lowered heating payments inside just a few months.

In conclusion, I initially thought the Tapo KE100 was a superb possibility for anybody desirous to improve from conventional TRVs to good TRVs. It was a flawed product however nice worth for cash.

With the current updates, that is now considerably higher and possibly the perfect reasonably priced possibility available on the market.
