Can anyone suggest trv devices suitable for intergration without the need for oem apps or servers?

Thanks in advance

The EQ-3 TRVs (bluetooth version) can be controlled via MQTT using https://github.com/softypit/esp32_mqtt_eq3 on an ESP32. Tasmota can’t do it (yet).

Thanks, the linky is broken but it contained all i needed to find the project ok..  one device ordered from amazon for a look see, Bet i find out my current 20yr old thermostatic valves work in a completely different way  or use a different thread/connection interface ;)  -  off for a detailed read now..  thanks again..

Mine came with a couple of adaptors. They fitted all but one of my 30 year old TRVs (I managed to buy a separate adaptor for that).

 

I got mine from Conrad

https://www.conrad.com/p/eqiva-cc-rt-ble-eq-wireless-thermostat-head-electronical-1543545

They also sell the adaptors.

Sounds very appealing as I want to get rid of my EQ-Max TRV's

What is the realistic max distance between the ESP32 and the TRV?
I see that many ESP32 boards, any recommendations or are they all more or less the same?

Thanks,
Ysbrand

There is an issue with the Bluetooth power on some ESP32s but I have 6 TRVs controlled by 2 ESP32s with about 5m to the furthest TRV.

Amazon sure do deliver promptly, So,  SoftyPits Esp32-eq3 interface is up, but not seeing the TRV,  Its a ble model but is not installed, just powered on and had date/time set.

I could RTFM ! But small print and a 18month delay in getting an eye op (cataracts) makes that an unattractive headache inducing prospect..

I suspect either BLE isnt enabled until the device has run through its set up calibration correctly or shaken hands with its expected app?
Or perhaps my ancient esp32 module has b/tooth issues  

Before i flash some BLE example sketches from the arduino ide to test my esp32 I thought i would check here to confirm if i shou,d be seeing the eq3 trv in a search list before its fully installed and or do i need to touch it with its expected app to wake it?  Or should i be validating my old esp32 is working as expected
(current distance between trv and esp is inches..  )

Thanks in advance ..

Press mode for 3 seconds then use rotary knob to get to BLE then select to turn it on.

Great, found that, then checking for any serial output with putty revealed the plugging in of a battery powered device to charge into the same usb hub (doh) caused the esp32 to brown out half way through the start up.  
Got over that hurdle way too slowly ..

Still no joy tho its a Model CC-RT-M-BLE-EQ not found explicitly in the incomplete list of compatible devices But it wears the Bluetooth name on its top! :(..Updated firmware perhaps

I monitored the serial output during scans with the device on with ble on and with it without batteries, they were identical outputs.

I used a windows box and a raspberry pi to scan for ble devices found loads 'unknown' but none advertising a public handle like suggested 

Monitoring the esp32 startup logs everything seems to start up and initialise ok without any error messages (once sufficient power was applied)

I dont want to 'touch' the device with the phone app just in case that triggers a further issue

And i have no AA cells to replace the ones in the box, they are very scarce here with lots of 1.2v nicad rechargable cells not upto Bluetooth broadcast as i have discovered with playstation remotes and similar.. 

hmmmmm

got a 2nd esp32 a more modern Mstick device installed/configured/scanned - same results :(

I have installed V 1.5.5 by copying each of the 4 x binary files from the releases page, although its labelled a stable release It shows up as a beta in the gui front page (usual oversight?)

and editing the install command to reflect win10 python 3.9 ie py -m pip install ......... COMX.........

is it worth charging a phone and installing the app to  see if that can connect? 

OR is there a known to be stable release i should try,, - straw clutching at my best

Did i get a faulty trv ????? Box was a bit battered, internal box too ?

Thanks again for any/all input,

Just Triple checking,  when i access / leave the BLE menu option on the EQ3 TRV it displays the OFF option indicating that the feature is enabled and ON 
I DO NOT SELECT By pressing the jog wheel button down, instead i press the menu/mode button to back out leaving the device with bluetooth ble ON.

Yeah im questioning EVERYTHING atm...

I’m using 1.51 beta

If you go  in via mode and  navigate to BLE it will say whether it’s on. It will say On when it’s on – press Mode twice to back out. If it doesn’t say on (it says Off) press the jog wheel. It will return to normal and Bluetooth should be on.

I suspect either BLE isnt enabled until the device has run through its set up calibration correctly or shaken hands with its expected app?

Sorry got it the wrong way round press the control wheel when it says On to turn it on. Pressing the wheel when it says Off turns it off.

Well well well Finally Installed and both versions the original 1.5.5 on my older esp32 and the newer module running 1.5.1can see and address the valve...

Lesson learnt..  It appears you can not bench test these, they need installing on a valve and need to perform the set up routine etc Before BLE coms are enabled!! the BLE feature required me to activate pairing in order to start it unlike the more passive ble devices i am used to (xiaomi miflora/mija sensors..) that advertise publicly?
desperate clicking led me to the pi scripts from the same team? or person  I have a Pi-0-w covering most of my home (radiators are at extremities however). so with 2 x esp32 ble extenders i should be able to cover the whole house no trouble..
Perhaps i didnt emphasise enough that i was bench testing prior to fitting..   

Anyway Thanks For the hand holding Very Much appreciated.. Full steam ahead.. 

btw the fit was a very easy screw off screw on job, no tools or sharp edge casualties..

Yes you get an F2 error f the stroke is too long (which you’d get if benchtesting)
