Allows for multiple SwitchBot buttons and curtains to be controlled via MQTT sent to ESP32. ESP32 will send BLE commands to switchbots and return MQTT responses to the broker. Also supports Meter/Temp Sensor

Hi there,

first of all a huuuge Thank you for the great work!!!

i was wondering if ther would/ will be a way to connect the contact & motion sensor in the near future?

thanks again

greets

I have 2 switchbot curtains paired together, one switchbot bot and one contact sensor connected to my wemos di mini eps32. Like I said after a 2 to 3 days of working my contact sensor stops reporting to my home assistant. It (the switchbot devices) give an unavailable status or continues to report the same last state but do not record any new event. I have everything up to date with firmware 1.1, your code is in version v6.12. Maybe I have too many connected device?

This is the connected devices code:

/* Switchbot Bot Settings / static std::map<std::string, std::string> allBots = { { "SwitchbotThermopompe", "C2:C2:78:DF:41:B4" }/, { "switchbottwo", "yY:yY:yY:yY:yY:yY" }*/ };

/* Switchbot Curtain Settings / static const int curtainClosedPosition = 10; // When 2 curtains are controlled (left -> right and right -> left) it's possible one of the curtains pushes one of the switchbots more open. Change this value to set a position where a curtain is still considered closed static std::map<std::string, std::string> allCurtains = { { "RideauxCuisine", "C6:BD:87:AE:EB:17" }/, { "curtaintwo", "yY:yY:yY:yY:yY:yY" }*/ };

/* Switchbot Meter Settings / static std::map<std::string, std::string> allMeters = { /{ "meterone", "xX:xX:xX:xX:xX:xX" }, { "metertwo", "yY:yY:yY:yY:yY:yY" }*/ };

/* Switchbot Contact Sensor Settings / static std::map<std::string, std::string> allContactSensors = { { "PortePrincipale", "D4:FB:FD:48:2F:6F" }/, { "contacttwo", "yY:yY:yY:yY:yY:yY" }*/ };

Every ~24 hours my ESP32 device becomes unavailable. I don't know if it's freezing or dropping off the network or what. Replugging it back in, it immediately becomes available again and works great (until it drops off again). I've tried a few different power sources in case something where was going on there, but no luck.

This is the ESP32 device I'm installed on:

HiLetgo ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA for Arduino IDE

Do you have any idea what this may be or if there's a way I could debug the device to find out what could be going wrong?

I have one of these: https://www.aliexpress.com/item/3256801743620798.html?spm=a2g0o.order_list.0.0.120a1802llozYz (the DEVKIT V1), which I thought was a DIOT, but I'm not certain anymore. It's been flashing as the DIOT just fine, but who knows. Anyway, I've flashed it and it's discovering the bot, but it won't discover the commands like my wrover will.

Here's a screenshot from MQTT explorer with only relevant parts (note how the bottom is missing (set = ):

They are the both connecting to the same device (but even when I only had the bottom one on, it didn't work.

Here's my config (expires in a month, but I can always repaste if needed): https://pastebin.com/7TbCT4FJ

Logs from serial monitor (with debug on): https://pastebin.com/jviG7Mtc

Without debug, it basically is just:

2:58:30.327 -> lld_pdu_get_tx_flush_nb HCI packet count mismatch (1, 2)
22:58:30.664 -> lld_pdu_get_tx_flush_nb HCI packet count mismatch (1, 2)
22:58:31.991 -> lld_pdu_get_tx_flush_nb HCI packet count mismatch (1, 2)
22:58:33.069 -> lld_pdu_get_tx_flush_nb HCI packet count mismatch (1, 2)
22:58:34.727 -> lld_pdu_get_tx_flush_nb HCI packet count mismatch (1, 2)
22:58:35.021 -> lld_pdu_get_tx_flush_nb HCI packet count mismatch (1, 2)
22:58:36.353 -> lld_pdu_get_tx_flush_nb HCI packet count mismatch (1, 2)

So I'm thinking that this is an issue with something going wrong with the model maybe? But I'm too new to microcontrollers to know. Any thoughts? Ways I can help you debug?

Hi,

thanks for the great work.

When I activate getBotResponse it takes several seconds before my bot reacts. After that the LED (only active while while command) stays on and after some time ESP lastwill goes to offline. I always can send only one command.

When i deactivate getBotResponse its super fast and i can send multiple commands. But would be really good to have a feedback. I also would process the "success" status myself, but with deactivation I only get status "connecting" or "commandSent".

Is it possible to just get the status, without the ESP32 is waiting for something? I got bot firmware 4.9, maybe its also related to a new firmware version? (dont know the release date of 4.9)

Hi, I'm controlling my pool heatpump, wich only has a Power press button, with a SwitchBot in Pressmode and your Firmware on an esp32 and it works very well. Now I want to automate it depending on the energy amount of my Solar Power. To do this I need the ON/OFF State of the bot. Can you please enhance your Firmware, so that one could send ON and OFF commands in Pressmode to press the bot and the /state Channel would report the last successful commanded State?

Hello,

I would like to flash a new ESP32. Now I become this Error:

What can I do? Thank you!

Is there a way to increase at which the bot responds to the esp32? With the app and phone it's pretty fast but with home assistant, there is a couple of seconds delay. Is there somewhere in the code I could modify the time it takes? Thank you!

Hi,

first of all: Thank you so much for this project! It works like a charm. :+1:

HomeAssistant has a MQTT discover feature. I would love to see this in your project. https://www.home-assistant.io/docs/mqtt/discovery/

Hi! I have the same issue as in thread #90 (starting directly after the first scan) but don't get it fixed! I tried to switch to the older version (Arduino ESP core 1.0.6) of the board infos and also downgraded to NimBLE Version 1.3.7, but now I get this compile error: More than one library found for "WiFi.h". Used: /Users/flori/Library/Arduino15/packages/esp32/hardware/esp32/1.0.6/libraries/WiFi Not used: /Applications/Arduino.app/Contents/Java/libraries/WiFi exec: "python": executable file not found in $PATH I am not sure how to get this working...

If i reinstall a newer version > 2.0, then compilation works fine again - but the problem isn't solved so far. Do you have any hints for me? Thanks! Florian

After upgrading to v7.0, it seems that after the initial boot/enable of the ESP32 (or restart of the MQTT broker), MQTT data other than lastwill is no longer updated for curtains and meters (these are all that I have to test on at the moment, so could be others experiencing the same issue).

I also tried forcing the botScanTime to a set interval (120 seconds) for the devices and used onlyActiveScan = true; but doesn't seem to make a difference. No updates for any of the device attributes come in.

This has been the case with both ESP32 library v1.0.6 (currently using) and v2.0.0.

Downgrading back to v6.12 seems to make everything work again.

Hi,

I followed all the instructions and used PlatformIO to flash to ESP32. I got the Plug Mini to appear in HA. But I couldn't control (turn on/off) the plug. My ESP chip is is ESP-WROOM-32.

I set the printSerialOutputForDebugging to true to debug. When I send a command from HA (eg, turn off the plug). These logs get printed out constantly

Device: 
big_monitor
Device value:

So I'm guessing this is a problem with connecting to the plug via bluetooth? The plug firmware is v1.5

I am getting this output when i run the sketch in Arduino-IDE on an Esp-Wroom board "wifi:timeout when WiFi un-init, type=4". The wifiscan sketch example works.

First off....ty for all the work you have put in to this, normal BLE and the old integration was too slow for me. Hopefullly you can help me fix my last issues with the esp32 way of communicating with switchbot devices....

Just 'flashed' (is that the right term?) my first board ever....and i'm succesfull in getting a meter and a bot through the esp board. However i added the BLE mac addressess of my two curtains that are near the esp32. They are not registering, eventhough I am sure the mac addresses are correct.

Could it have something to do with passwords on these devices? And if so, do I need to reset the curtains to get rid of this or is there some other solution?

thanks in advance

I have an esp32 (AZ-delivery) working well with two switchbot curtains (paired). It's less than a metre away from the curtain bots.

I haven't actually noticed any functional issues yet, but I can see it's registering as unavailable a few times throughout the day. The link quality seems good, and I'm not having any other network issues that'd cause this as far as I'm aware.

I'm actually not 100% on how best to debug this, I can't see any logs relating to esp/Mqtt in home assistant.

Any help debugging would be much appreciated!

I believe this is related to the NimBLE library as discussed here: https://github.com/h2zero/NimBLE-Arduino/issues/351

My Switchbot ESP32 devices occasionally panic and reboot.

I'm currently testing a fix here https://github.com/TheHolyRoger/SwitchBot-MQTT-BLE-ESP32/tree/feat/resetBluetoothStack

Resetting the bluetooth stack on a 5min interval seems to help the problem for me so far
