Having problems adding Heatmiser thermostat to configuration.yaml

Configuration
44

Hi @nigelc and @Andyh747, My Netmonitor just died so I’m really keen to hook up my Heatmiser V3 system to Home Assistant. Your code looks like it will be essential, Nigel (I have PRT-NTS thermostats).

Could you tell me which terminals on the UH1 I should wire up to which terminals on an RS485 to tcp/ip adapter? I guess it is the touchpad group of terminals but do you know which of them specifically?

The adapter I’m thinking of is this one, which has terminals labelled VIN, GND, A+, B- alongside a 12v DC port.

Hi @ozpac

On my system, with the Touchpad, I connected the RS485 adaptor data terminals to the C & D connectors on the Touchpad. I did try connecting to the Y & B connectors on the UH1 but had problems with this (probably due to the touchpad clashing with the RS4856 adaptor). I assume that without the touchpad, I would have connected directly to the Y&B terminals, which is what I suggest you do. I believe RS485 is a differential signal, so it doesn’t matter which way round you connect the A+, B- terminals.

Good luck. Please let me know how you get on

Thanks kindly, as soon as the device arrives I’ll test it out and will let you know how I go. Thanks again!

Hi again @nigelc, I’ve set up my RS485<>Ethernet adapter and installed your code [GitHub - NigelCoxon/Hass-heatmiser: Home Assistant Component for Heatmiser PRT-N Stats] as per its readme… but what should I do next? I don’t see the integration show up as installed (nor any devices or entities listed with names like ‘heatmiser’). Your Heatmiser integration shows up as available to be installed but says ‘This device cannot be added from the UI’. Please would you let me know what I should do to create toggles/widgets/controls in the UI to interact with my thermostats?

Update: I fixed it. Added the logging code to configuration.yaml and saw from there that I had not configured the baud rate correctly for my rs485 adapter. After that the entities appeared.
This is such a wonderful bit of code, thank you and others involved, you’ve not only saved my system, but upgraded it too.

@ozpac Glad you got it working OK. . Get in touch if you have any other issues

Hi @nigelc, I’m hoping that you are still available to provide some assistance please. I was very excited to find that the code you have written exactly matches my system (11 PRT-N thermostats and the original Touchpad) and that I might be able to control the Heatmiser heating system through HA. I have HA (version 2024.6.0) running on a Raspberry Pi 4 and loaded your code exactly as described in your Readme file. I bought the exact same RS485 to Ethernet board suggested by @ozpac (the A+ and B- pins connected to the C and D terminals of the Touchpad respectively). As an initial test, I tried running with just 3 thermostats but sadly I’m getting errors. I can’t work out if the problem is in my configuration, or in my hardware setup. I can see that HA has found and made contact with my RS485 converter board; I do see a panel appear in my HA dashboard (but strangely only for the first of the three thermostats?); but then I get an error ‘no data read from thermostat’. And that’s as far as I can get - I need some help please. The RS485 board I have configured as 4800 baud, 8 data bits, 1 stop bit, no parity, no flow control, Work mode: TCP server - is that correct? I tried swapping the RS485 lines over but that made no difference. I’m stuck - I feel like I’m very close but as yet, no cigar

My configuration:

Hi @calisto99
I’m happy to help if I can, but I have to say I haven’t looked at this for a long time. My system just keeps on going
.
Your config looks OK
Sorry for the warnings about the deprecated constants - I have to fix that before the end of 2024

Could you set the logging to debug for the 2 elements of the component, either in configuration.yaml (or from the Developers Tools) and let me see the detailed logging.
custom_components.heatmiser_ndc.climate: debug
custom_components.heatmiser_ndc.heatmiser: debug

Also I don’t think I have seen this error before:
Platform heatmiser_ndc does not generate unique IDs. ID Heatmiser Prt 0 already exists - ignoring climate.hallway

I’ll have to investigate this

Nigel

Thanks ever so much for getting back to me @nigelc - I would have replied earlier but have not yet worked out how to get an email notification when there’s been a reply. I’m a bit new to HA so I hope I’ve enabled the logging properly. Here’s the detailed log:

Yes, I could see that the warnings were just for deprecated constants so didn’t think that was the issue. The Prt 0 error suggested to me that all three of my stats were somehow assigned the same ID but I’m just guessing - I’m hoping you will be able to give me some pointers from the logs. Thanks again, much appreciated

Okay, I‘ve got to the root cause of my problems. I found that I got the same HA errors even if I disconnected the RS485 lines altogether - and when I probed the RS485 lines with an oscilloscope, they weren’t ‘wiggling’ at all. So I concluded that the problem must be with the RS485-to-Ethernet converter board. The baud rate etc. was set correctly but I noticed another section in the converter board config labelled MODBUS parameters - I set one of those parameters to ‘closed’ and another to ‘disable’ and bingo! The whole thing sprung to life. The converter board I used is widely available but the guides for setting it up are virtually non-existent, so it was largely guess work for many of the parameters. Should this be useful to anyone else, I’ll post my full RS485-to-Ethernet converter board configuration settings here.

This is the converter board I’m using:

Many thanks to @nigelc for putting this all together. Now that I’ve got the hardware side worked out, it all works very nicely indeed. Being able to set the frost protection temperature via HA is a real bonus too :+1:

@calisto99 Glad to hear you got it working. Looking at your logs did reveal a weakness in the error handling in my code. Normally if a read fails (eg CRC error, no data read) the code just tries again on the next update cycle. However, if the first read fails, the initialisation doesnt work properly and Hass gives up. I’ll fix this soon together with the deprecated constants

Yes, thanks @nigelc I’m just happy it’s now working for me but obviously I will be very keen to have your updated code when it’s ready please. No data read during initialisation is a good one to catch as that points to IP comms with the converter board being good but RS485 comms with the stats is not. Anyway, I know a lot more about your code now, which is a good thing.

One of my thermostats (the PRTHW-N, which thankfully is one of the supported models) controls the heating as well as the hot water. The cherry on the cake would be the facility to enable and disable the hot water timer schedule. Aside from there being no where to accommodate this function in the UI, I’m not sure this specific feature is even supported by the V3 protocol (although there is an AWAY MODE, which could amount to the same thing functionally). At some point, I will look to see how feasible it is to add this functionality, even if it’s something that’s sent as a separate command string rather than controlled through the UI. I would first need to get a lot more familiar with the V3 protocol and that HA code of course! Is this something that you’ve ever looked at or think might be possible with the code structure as it is? I do like a challenge :stuck_out_tongue_closed_eyes:
